Introduction
1-1 Main Board Overview
The main board is a new-generation AGP Pentium® main board with high
performance in rendering and texture for 3D Graphics. Based on Apollo MVP3
chipset, the main board has intergrated the latest advances in processor, memory,
I/O technologies into an AT form factor. It is also designed for the upcoming 100
MHz F.S.B CPUs, like AMD K6-2/K6-3 series or Cyrix MII CPUs.
The main board utilizes VIA Apollo MVP3 and supports new architects such as
high-speed AGP graphic port, SDRAM, Ultra DMA/33, bus master IDE and USB
port. It has three Dual In-line Memory Modules (DIMM) which can be installed
with SDRAM memory. The memory subsystem supports up to 512Mbyte SDRAM
of non-buffered 3.3V using standard 168-pin DIMM sockets.
The main board implements high performance I/O Controller utilizes with fully

(with 16 bytes FIFO, up to 460K baud rate) Serial Port, ECP (Enhanced
Capabilities Port), EPP (Enhanced Parallel Port) parallel port, Infrared IrDA
(HPSIR), and Amplitude Shift Keyed IR. (ASKIR) port.
The main board supports 3*PCI & 3*ISA for highest performance I/O add-on
adapter cards. The system board supports three Matrix Independent for complete
multiple PCI adapters operation up to 133MB/s data transfer rate on PCI bus
compared to 33MB/s on EISA bus, synchronized operation CPU to PCI Interface
for best graphical performance, 120MB/s PCI to system DRAM together with
utilizing Snoop Ahead Features, and support back to back sequential CPU to PCI
Memory writes to PCI Burst Write for full PCI through put.

AGP (Accelerated Graphic Port) is the new bus standard that allows the bus
speed to run at 66 MHz with up to 133 MHz data transfer capabilities, which is
four times as fast as that of the PCI bus. At this speed, the AGP graphic cards
can transfer data up to 528MB/second. This high transfer capabilities enables
3D graphic applications, multiple media applications, uncompressed to run
smoothly and display in broadcasting quality.
There are three PCI slots on board. 133MB/s data transfer rate on PCI bus can
be compared to 33MB/s on EISA bus or 8MB/s on ISA bus. Synchronize
Operation CPU to PCI interface for good graphic performance.
There are 3 standard 32-bit ISA slots on board. All of them are bus mastering.

3-2 Standard CMOS Setup
The ”Standard CMOS Setup” allows user to configure system setting such as
current date and time, type of hard disk drive installed in the system, floppy
drive type, and the type of display monitor. Memory size is auto detected by the
BIOS and displayed for your reference. When a field is highlighted (direction keys
to move cursor and <Enter> key to select). The entries in the field will be changed
by pressing <PageDown> or <PageUp> key or user can enter new data directly
from the keyboard.

1. TYPE : select from "1" to "45" to fill remaining fields with redefined values
of disk drives. Select "USER" to fill the remaining fields. Select
"AUTO" to detect the HDD type automatically.
2. SIZE : the hard disk size. The unit is mega byte(MB).
3. CYLS : the cylinder number of the hard disk.
4. HEAD : the read/write head number of hard disk. The range is from "1" to
"16".
5. PRECOMP: the cylinder number at which the disk drive changes the write
timing.
6. LANDZ : the cylinder number that the disk drive heads (read/write) are seated
when the disk drive is parked.
7. SECTOR : the sector number of each track defined on the hard disk. The range
is from "1" to "64".
8. MODE :select "AUTO" to detect the mode type automatically. If your hard
disk supports the LBA mode, select "LBA" or "LARGE".
However, if your hard disk cyclinder is more than 1024 and does not
support the lba function, you have to set at "LARGE.” Select
"NORMAL" if your hard disk supporting cylinder is below 1024.
Note 1: if hard disk primary master/slave and secondary master/slave were set to
“auto,” the hard disk size and model will be auto detected on display during POST.
Note2: "halt on" is to determine when to halt the system by the BIOS if error occurs
during POST.

2. LBA (Logical Block Addressing) Mode
A new HDD accessing method to overcome the 528 MB bottleneck. The number
of cylinders, heads & sectors shown in setup may not be the number physically
contained in the HDD. During HDD accessing, the ide controller will transform
the logical address described by sector, head & cylinder into its own physical
address inside the HDD.
The maximum HDD size supported by LBA mode is 8.4 GB which is obtained by
the following formula:

3. Large Mode
Extended HDD access mode supported by Award® software. Some IDE HDDs
contain more than 1024 cylinder without LBA support (in some cases, user do not
want LBA). The Award® BIOS provides another alternative to support these
kinds of large mode:

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiplied by 2. A
reverse transformation process will be made inside int 12h in order to access the
right HDD address the right HDD address!

To support LBA or large mode of HDDs, there must be some
softwares involved. All these softwares are located in the Award®
HDD service routine (int 13h). It may be failed to access a HDD with LBA
(large) mode selected if you are running under an perating system which
replaces the whole int 13h. Unix operating systems do not support either LBA or
large and must utility the standard mode. Unix can support drives larger than
528MB.

3-10 Load Setup Defaults
"Load Setup Defaults" loads optimized settings which are stored in the BIOS
ROM. The auto-configured settings only affect “BIOS Features Setup” and
“Chipset Features Setup” screens. There is no effect on the standard CMOS
setup. To use this feature, highlight it on the main screen and press the <Enter>
key. A line will appear on screen asking if you want to load the setup default
values. Press the <Y> key and then press the <Enter> key . The setup defaults
will then load. Press <N> if you don't want to

Q&A
Errors Messages During Power On Self Test
During power on self test (post), BIOS will automatically detect the system
devices. Below is the questions that users may always meet. The user may press
“Esc” key to skip the full memory test.
1. Beep sound
On power on, the system make beep sound to offer different messages. If the
system is configured correctly, it prompts a short beep to show correct the
devices configuration is done correctly. When VGA card and DIMM modules
are not plugged well, the system makes longer and constant beep sounds.
2. BIOS ROM checksum error
It indicates the checksum of the BIOS code is not right and system will always
halt on power on screen. Contact the dealer to exchange a new BIOS.
3. CMOS battery fails
It indicates the CMOS battery does not work. Contact the dealer to exchange
a new BIOS.
4. CMOS checksum error
It indicates the CMOS checksum is incorrect. Load the default values in
BIOS to solve this problem. This error may result from a weak BIOS, so
exchange a new BIOS if necessary.
5. Hard disk initialize
Please wait a moment…
Some hard drives require more time to initialize.
MVP3 Main Board

5MVP3
6. Hard disk install failure
The system can not find or initialize the hard drive controller or the drive.
Check if the controller is set correctly. If no hard disk is installed, “Hard
drive selection” must be set to “none.”
7. Keyboard error or no keyboard present
This means the system can not initialize the keyboard. Check if the keyboard
is plugged well and be sure no keys are pressed during POST.
8. Keyboard is lock out- Unlock the key
Normally when this message comes out, check if there is anything mis-placed
on the keyboard. Be sure nothing touches the keys.
9. Memory test fails
There will be more information to specify the type and location of the memory
error.
10. Primary master hard disk fail
The BIOS find an error in the primary master hard disk drive.
11. Primary slave hard disk fail
The BIOS finds an error in the primary slave hard disk drive.
12. Secondary master hard disk fail
The BIOS finds an error in the secondary slave master hard disk drive.
13. Secondary slave hard disk fail
The BIOS finds an error in the secondary slave IDE hard disk drive.

5-2 Frequently Asked Questions
Below is questions users always come out with. Q is for question. A is for
answer.
Q: Why can’t my AGP card work under Win 95?
A: Windows 95 OSR2.0 does not support AGP function. You must install “USB
support” file to enable this function. After installing, choose “enable for “ASSIGN
IRQ FOR USB” in BIOS PNP/PCI configuration setup.
Q: Why can’t the CPU frequency be adjusted to 100 MHz ?
A: The BIOS will automatically detect the CPU frequency (66MHz or 100 MHz).
Therefore, if your CPU frequency cannot be adjusted to 100 MHz, then your CPU
may be 66 MHz. In BIOS “speed setup,” there are other frequencies, like 75 MHz,
83 MHz, 103 MHz, 102 MHz, 112 MHz, 133MHz. These are for internal test
only. No guarantee is provided since this is not included in chipset specification.
Q: Why is my system not stable with 100 MHz CPU?
A: There are many reasons for this condition. One of the most common is that
SDRAM does not match PC-100 specification. When system is operated under
100 MHz, in addition to 100 MHz CPU, SDRAM must be PC-100 DIMM too.
