III. INSTALLATION

APIC Dual CPU Selection (JP14)

This jumper turns on or off the multiprocessor operating system’s support for multiprocessors regardless of the number of processors installed in the system.

For single processor operating systems (e.g. DOS, OS/2 Warp, Win3.1x,

Win95, Nextstep): You can use one (or two) processor(s) and this “APIC Dual

CPU Selection” jumper has no function (you may leave on default setting).

For multiprocessor operating systems (e.g. WinNT, Unixware, SCO Unix

MP, Solaris 2.51): You can use one or two processors and Enable this “APIC

Dual CPU Selection” jumper. This solution allows some multiprocessor operating systems to upgrade from one processor to two processors in the future without having to reinstall a multiprocessor OS. Otherwise Disable the dual processor support in a multiprocessor operating system if for some reason necessary.

IV. BIOS SOFTWARE

6. BIOS Setup

The motherboard supports two programmable Flash ROM chips: 5 Volt and 12

Volt. Either of these memory chips can be updated when BIOS upgrades are released. Use the Flash Memory Writer utility to download the new BIOS file into the

ROM chip as described in detail at the beginning of BIOS Software section IV.

All computer motherboards provide a Setup utility program for specifying the system configuration and settings. If your motherboard came in a computer system, the proper configuration entries may have already been made. If so, invoke the Setup utility, as described later, and take note of the configuration settings for future reference; in particular, the hard disk specifications.

If you are installing the motherboard, reconfiguring your system or you receive a

Run Setup message, you will need to enter new setup information. This section describes how to configure your system using this utility.

The BIOS ROM of the system stores the Setup utility. When you turn on the computer, the system provides you with the opportunity to run this program. This appears during the Power-On Self Test (POST). Press the <Delete> key to call up the

Setup utility. If you are a little bit late pressing the mentioned key(s), POST will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, reset the system by simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys, or by pushing the Reset button on the system case. You can also restart by turning the system off and then back on again. But do so only if the first two methods fail.

When you invoke Setup, the CMOS SETUP UTILITY main program screen will appear with the following options:

IV. BIOS SOFTWARE

Load Defaults

The “Load BIOS Defaults” option loads the minimized settings for troubleshooting. “Load Setup Defaults”, on the other hand, is for loading optimized defaults for regular use. Choosing defaults at this level, will modify all applicable settings.

A section at the bottom of the above screen displays the control keys for this screen.

Take note of these keys and their respective uses. Another section just below the control keys section displays information on the currently highlighted item in the list.

Standard CMOS Setup

This “Standard CMOS Setup” option allows you to record some basic system hardware configuration and set the system clock and error handling. If the motherboard is already installed in a working system, you will not need to select this option anymore. However, if the configuration stored in the CMOS memory on the board gets lost or damaged, or if you change your system hardware configuration, you will need to respecify the configuration values. The configuration values usually get lost or corrupted when the power of the onboard CMOS battery weakens.

The entries for specifying the hard disk type include CYLS (number of cylinders),

HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ

(landing zone), SECTOR (number of sectors) and MODE. The SIZE field automatically adjusts according to the configuration you specify. The documentation that comes with your hard disk should provide you with the information regarding the drive specifications.

The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI drives. This entry provides three options: Normal, Large, LBA, or Auto (see below). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow larger IDE hard disks; set it to Large for drives over 528MB that do not support LBA. Large type of drive can only be used with MS-DOS and is very uncommon. Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup (New Feature)

For each field: Primary Master, Primary Slave, Secondary Master, and Secondary

Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE drives during bootup. This will allow you to change your hard drives (with the power off) and then power on without having to reconfigure your hard drive type. If you use older hard drives which do not support this feature, then you must configure the hard drive in the standard method as described above by the "User" option.

NOTE: After the IDE hard disk drive information has been entered into BIOS, new

IDE hard disk drives must be partitioned (such as with FDISK) and then formatted before data can be read from and write on. Primary IDE hard disk drives must have its partition set to active (also possible with FDISK).

BIOS Features Setup

This “BIOS Features Setup” option consists of configuration entries that allow you to improve your system performance, or let you set up some system features according to your preference. Some entries here are required by the motherboard’s design to remain in their default settings.

16

A section at the lower right of the screen displays the control keys you can use. Take note of these keys and their respective uses. If you need information on a particular entry, highlight it and then press the <F1> key. A pop-up help menu will appear to provide you with the information you need. To load the last set values, press the

<F5> key. <F6> and <F7> load the BIOS default values and Setup default values, respectively.

Details of BIOS Features Setup:

Virus Warning

This field protects the boot sector and partition table of your hard disk against accidental modifications. Any attempt to write to them will cause the system to halt and display a warning message. If this occurs, you can either allow the operation to continue or use a bootable virus-free floppy disk to reboot and investigate your system. The default setting is “Disabled”. This setting is recommended because conflicts with new operating systems. Installation of new operating systems require that you disable this to prevent write errors.

CPU Internal Cache

These fields allow you to Enable (default) or Disable the CPU’s “Level 1” primary cache. Caching allows better performance.

ASUS C-P55T2D User’s Manual

IV. BIOS SOFTWARE

External Cache

These fields allow you to Enable (default) or Disable the CPU’s “Level 2” secondary cache. Caching allows better performance.

Quick Power On Self Test

This field speeds up the Power-On Self Test (POST) routine by skipping retesting a second, third, and forth time. Setup default setting for this field is Enabled. A complete test of the system is done on each test.

HDD Sequence SCSI/IDE First (New Feature!)

When using both SCSI and IDE hard disk drives, IDE is always the boot disk using drive letter C (default setting of IDE). This new feature allows a SCSI hard disk drive to be the boot disk when set to SCSI. This allows multiple operating systems to be used on both IDE and SCSI drives or the primary operating system to boot using a SCSI hard disk drive.

Boot Sequence

This field determines where the system looks first for an operating system. Options are C,CDROM,A; CDROM,C,A; A,C; C,A The setup default setting is to check first the hard disk and then the floppy drive; that is, C, A.

Swap Floppy Drive

When enabled, the BIOS swaps floppy drive assignments so that Drive A becomes

Drive B, and Drive B becomes Drive A under DOS. By setup default, this field is set to Disabled.

Boot Up Floppy Seek

When enabled, the BIOS will seek the floppy "A" drive one time. By setup default, this field is set to Disabled.

Floppy Disk Access Control

This allows protection of files from the computer system to be copied to floppy drives by allowing the setting of Read Only to only allow reads from the floppy but not writes. The setup default R/W allows both reads and writes.

Boot Up NumLock Status

This field enables users to activate the Number Lock function upon system boot.

The setup default setting for this field is On.

Boot Up System Speed

This has not function and should be left at the setup default of High.

IDE HDD Block Mode Sectors

This field enhances hard disk performance by making multi-sector transfers instead of one sector per transfer. Most IDE drives, except older versions, can utilize this feature. By setup default, this field is set to HDD MAX, other selections are Dis-

abled 2, 4, 8, 16, and 32.

Typematic Rate Setting

When enabled, you can set the two typematic controls listed next. Setup default setting is Disabled.

Typematic Rate (Chars/Sec)

This field controls the speed at which the system registers repeated keystrokes.

Options range from 6 to 30 characters per second. Setup default setting is 6; other settings are 8, 10, 12, 15, 20, 24, and 30.

Typematic Delay (Msec)

This field sets the time interval for displaying the first and second characters. Four delay rate options are available: 250ms, 500ms, 750ms and 1000ms. Setup default value is 250ms.

Security Option

This field determines when the system prompts for the password. The default setting is System, where the system prompts for the User Password every time you boot up. The other option is Setup, where the system always boots up, and prompts for the Supervisor Password only when the Setup utility is called up. You can specify a password by using the Supervisor Password or User Password option from the main screen as explained later in this section.

PS/2 Mouse Function Control

The default of Auto allows the system to detect a PS/2 Mouse on bootup. If detected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expansion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expansion cards and therefore the PS/2 Mouse will not function.

PCI/VGA Palette Snoop

Some display cards that are nonstandard VGA such as graphics accelerators or MPEG

Video Cards may not show colors properly. The setting Enabled should correct this problem. Otherwise leave this on the setup default setting of Disabled.

OS/2 Onboard Memory > 64M

When using OS/2 operating systems with installed DRAM of greater than 64MB, you need to Enable this option otherwise leave this on the setup default of Disabled.

MPS 1.4 Support

MPS 1.4 is Intel's new Multi-Processor Specification. Some MP operating system still cannot support it. If your MP operating system cannot support MPS 1.4, you must leave this feature on the default of Disabled

.....................................................................................................................................

Video BIOS Shadow

This field allows you to change the video BIOS location from ROM to RAM. Relocating to RAM enhances system performance, as information access is faster than the ROM. Setup default setting is Enabled.

C8000-CBFFF to DC000-DFFFF

These fields are used for shadowing other expansion card ROMs. If you install other expansion cards with ROMs on them, you will need to know which addresses the ROMs use to shadow them specifically. Shadowing a ROM reduces the memory available between 640KB and 1024KB by the amount used for this purpose. Leave on default setting of Disabled.

Video BIOS Cacheable

Allows the Video BIOS to be cached to allow faster execution. (Leave on default setting of Enabled)

Memory Hole at 15M - 16M

Enabling this features reserves 15MB to 16MB memory address space to ISA expansion cards that specifically require this setting. This makes the memory from

15MB and up unavailable to the system. Expansion cards can only access memory up to 16MB. The default is Disabled.

[DRAM and ECC]

If all your DRAM modules have parity chips (e.g. 8 chips + 4 parity chips), they are considered 36bits. This motherboard sums the memory per bank and therefore two modules will give 72bits and the following will be displayed:

If your DRAM modules do not have parity chips (e.g. 8 chips), they are considered

32bits and the following will be displayed instead:

The default of Disabled for Memory parity SERR# (NMI) will not show memory errors on your monitor. When using parity DRAM modules, you can select from the default of Parity or ECC (Error Checking and Correcting) to correct 1 bit memory errors that may occur in the memory. (See section III of the Baseboard User’s Manual for more information on DRAM memory modules.)

.......................................................................................................................................

Onboard FDC Controller

When enabled, this field allows you to connect your floppy disk drives to the onboard floppy drive connector instead of a separate controller card. If you want to use a different controller card to connect the floppy drives, set this field to “Disabled”. Default setting is Enabled.

Onboard FDC Swap A: B:

This field reverses the drive letter assignments of your floppy disk drives in the

Swap AB setting, otherwise leave on the default setting of No Swap. This works separately from the BIOS Features floppy disk swap feature. It is functionally the same as physically interchanging the connectors of the floppy disk drives.

Onboard Serial Port 1

Settings are 3F8H/IRQ4 (default), 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Dis-

abled for the onboard serial connector.

Onboard Serial Port 2

Settings are 3F8H/IRQ4, 2F8H/IRQ3 (default), 3E8H/IRQ4, 2E8H/IRQ10, and Dis-

abled for the onboard serial connector.

ASUS C-P55T2D User’s Manual

IV. BIOS SOFTWARE

Onboard Parallel Port

This field sets the address of the onboard parallel port connector. You can select either: 3BCH / IRQ 7, 378H / IRQ 7 (default), 278H / IRQ 5, Disabled. If you install an I/O card with a parallel port, ensure that there is no conflict in the address assignments. The PC can support up to three parallel ports as long as there are no conflicts for each port.

Parallel Port Mode

This field allows you to set the operation mode of the parallel port. The setting

Normal, allows normal-speed operation but in one direction only; EPP allows bidirectional parallel port operation at maximum speed; ECP allows the parallel port to operate in bidirectional mode and at a speed faster than the maximum data transfer rate; ECP+EPP (default) allows normal speed operation in a two-way mode.

ECP DMA Select

This selection is available only if you select ECP or ECP+EPP in the

Parallel Port Mode. Select either DMA Channel 1, 3 (default), or Disable.

UART2 Use Infrared

When enabled, this field activates the onboard infrared feature and sets the second serial UART to support the infrared module connector on the motherboard. If your system already has a second serial port connected to the onboard COM2 connector, it will no longer work if you enable the infrared feature. By default, this field is set to Disabled, which leaves the second serial port UART to support the COM2 serial port connector. See section III of the Baseboard User’s Manual for the IrDA-com- pliant infrared module connector.

Onboard PCI IDE Enable

You can select to enable the primary IDE channel, secondary IDE channel, both

(default), or disable both channels (for systems with only SCSI drives).

IDE 0 Master/Slave Mode, IDE 1 Master/Slave Mode

Each channel (0 and 1) has both a master and a slave making four IDE devices possible. Because each IDE device may have a different Mode timing (0, 1, 2, 3, 4), it is necessary for these to be independent. The default setting of Auto will allow auto-detection to ensure the optimal performance.

Power Management Setup

This “Power Management Setup” option allows you to reduce power consumption.

This feature turns off the video display and shuts down the hard disk after a period of inactivity.

22

Details of Power Management Setup:

Power Management

This field acts as the master control for the power management modes. There are four options: Max Saving, Min Saving, Disabled, and User Defined. Max Saving puts the system into power saving mode after a brief period of system inactivity;

Min Saving is almost the same as Max Saving except that this time the system inactivity period is longer; Disabled disables the power saving features; User Defined allows you to set power saving options according to your preference.

IMPORTANT: Advanced Power Management (APM) should be installed to keep the system time updated when the computer enters suspend mode activated by the BIOS Power Management. For DOS environments, you need to add DEVICE=C:\DOS\POWER.EXE in you CONFIG.SYS. For Windows 3.1x

and Windows 95, you need to install Windows including the APM feature. A battery and power cord icon labeled "Power" will appear in the "Control Panel."

Choose "Advanced" in the Power Management Field.

Video Off Option

This field determines when to activate the video off feature for monitor power management. The settings are Susp, Stby->Off (default), Suspend->Off, Always On, and All Modes->off.

ASUS C-P55T2D User’s Manual

IV. BIOS SOFTWARE

Video Off Method

This field defines the video off features. Three options are available: V/H SYNC +

Blank, DPMS, and Blank Screen. The first option, which is the default setting, blanks the screen and turns off vertical and horizontal scanning; DPMS (acronym for Display Power Management System) allows the BIOS to control the video display card if it supports the DPMS feature; Blank Screen only blanks the screen. Use the latter for monitors that do not support the “Green” (no power management) feature.

Take note that a screen saver software does not work with this feature. While the monitor is shut off, this software cannot display.

Suspend Switch

This field enables or disables the SMI connector on the motherboard. This connector connects to the lead from the Suspend switch mounted on the system case. Default setting for this field is Enabled.

Doze Speed, Stdby Speed

These two fields set the CPU speed during each mode. The number indicates what the normal CPU speed is divided by.

PM Timers

This section controls the time-out settings for the Power Management scheme. The fields included in this section are “HDD Power Down”, which places the hard disk into its lowest power consumption mode, and the Doze, Standby and Suspend system inactivation modes.

The system automatically “wakes up” from any power saving mode when there is system activity such as when a key is pressed from the keyboard, or when there is activity detected from the enabled IRQ channels.

HDD Power Down shuts down any IDE hard disk drives in the system after a period of inactivity. This time period is user-configurable to 1-15 Mins or Disable.

This feature does not affect SCSI hard drives.

The Doze Mode, Standby Mode, and Suspend Mode fields set the period of time after which each of these modes activate. At Max Saving, these modes activate sequentially (in the given order) after one minute; at Min Saving after one hour.

ASUS C-P55T2D User’s Manual 23

IV. BIOS SOFTWARE

PM Events

This section sets the wake-up call of the system. If activity is detected from any enabled IRQ channels in the left-hand group, the system wakes up from suspended mode. You can enable power management for IRQs 3 ~ 15 individually in the list at the right of the screen. The power management feature will work on the enabled

IRQ channels.

Take note that a Microsoft serial mouse or compatible will use either COM1 (IRQ4) or COM2 (IRQ3), and a PS/2 mouse will use IRQ12. If you know which IRQ your mouse is using, you can enable the Wake-up Event for that IRQ here and the system will wake up when you move the mouse or click its button.

.....................................................................................................................................

Sleep Items (IRQ3-IRQ15)

You can individually Enable or Disable each IRQ to include in the sleep function.

IRQ8 (Real Time Alarm) is usually set to Disable so that any software alarm clock or event calendar can wake up the system.

PNP and PCI Setup

This “PNP and PCI Setup” option configures the PCI bus slots. All PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to this value.

24

The first four fields on the screen set how IRQ use is determined for each PCI slot.

The default setting for each field is Auto, which uses auto-routing to determine IRQ use. The other options are manual settings of 14 or 15 for each slot.

IV. BIOS SOFTWARE

PCI Latency Timer

The default setting of “32 PCI Clock” enables maximum PCI performance for this motherboard.

IRQ xx Used By ISA

These fields indicate whether or not the displayed IRQ for each field is being used by a Legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The first option, the default value, indicates either that the displayed IRQ is not used or an ISA Configuration Utility (ICU) is being used to determine if an ISA card is using that IRQ. If you install a Legacy ISA card that requires a unique IRQ, and you are not using an ICU, you must set the field for that IRQ to Yes. For example: If you install a Legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Yes.

......................................................................................................................................

DMA x Used By ISA

These fields indicate whether or not the displayed DMA channel for each field is being used by a Legacy (non-PnP) ISA card. Available options include: No/ICU and Yes. The first option, the default setting, indicates either that the displayed

DMA channel is not used or an ICU is being used to determine if an ISA card is using that channel. If you install a Legacy ISA card that requires a unique DMA channel, and you are not using an ICU, you must set the field for that channel to Yes.

ISA MEM Block BASE

This field allows you to set the base address and block size of a Legacy ISA card that uses any memory segment within the C800H and DFFFH address range. If you have such a card, and you are not using an ICU to specify its address range, select a base address from the six available options; the ISA MEM Block SIZE field will then appear for selecting the block size. If you have more than one Legacy ISA card in your system that requires to use this address range, you can increase the block size to either 8K, 16K, 36K, or 64K. If you are using an ICU to accomplish this task, leave ISA MEM Block BASE to its default setting of No/ICU.

NCR SCSI BIOS

The default uses Auto settings for the onboard NCR SCSI BIOS (see section IV of

Baseboard User’s Manual). If you wish not to use the onboard NCR SCSI BIOS, choose Disabled

USB Function

This motherboard supports Universal Serial Bus (USB) devices but current operating systems do not. The default is set to Disabled until support disks and USB devices are available in which time you can set this function to Enabled.

Desktop Management Interface (DMI)

Introducing the DMI Configuration Utility

This motherboard supports DMI within the BIOS level and provides a DMI Configuration Utility to maintain the Management Information Format Database (MIFD).

DMI is able to auto-detect and record information pertinent to a computer’s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size. The onboard BIOS will detect as many system information as possible and store those collected information in a 4KB block in the motherboard’s Flash EPROM and allow the DMI to retrieve data from this database. Unlike other BIOS software, the BIOS on this motherboard uses the same technology implemented for Plug and

Play to allow dynamic real-time updating of DMI information versus creating a new

BIOS image file and requiring the user to update the whole BIOS. This DMI Configuration Utility also allows the system integrator or end user to add additional information into the MIFD such as serial numbers, housing configurations, and vendor information. Those information not detected by the motherboard BIOS and has to be manually entered through the DMI Configuration Utility and updated into the

MIFD. This DMI Configuration Utility provides the same reliability as PnP updating and will prevent the refreshing failures associated with updating the entire BIOS.

System Requirements

The motherboard BIOS must support DMI. The following motherboards do not support DMI:

• P/I-P6RP4 (not supported)

• PCI/E-P54NP4 (not supported)

• PCI/I-P54NP4D (not supported)

The DMI Configuration Utility (DMICFG.EXE) must be ran in real mode in order for the program to run, the base memory must be at least 180K. Memory managers like HIMEM.SYS (required by windows) must not be installed. You can boot up from a system diskette without AUTOEXEC.BAT and CONFIG.SYS files, “REM”

HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass your

AUTOEXEC.BAT and CONFIG.SYS files.
