2-1 Motherboard Layout
The P55-TV is designed with Intel 82430VX PCIset chipset which is developed
by INTEL Corporation to fully support Pentium Processor PCI/ISA system. The
Intel 82430VX PCIset chipset prpovides increased integration and improved
performance designs. The chipset provides an integrated IDE controller with two
high performance IDE interfaces for up to four IDE devices (hard devices, CDROM device, etc). The Winbond W83877F Super I/O controller provides the
standard PC I/O function: floppy interface, two 16 Byte FIFO serial ports and EPP/
ECP capable parallel port. The P55-TV layout is shown in previous page (left
page) for user's reference. Care must be taken when inserting memory modules,
inserting CPU or even plugging PCI card into associated slots to avoid damaging
any circuits or sockets on board. A cooling fan is strongly recommended when
installing P54C/P54CTB/P55C/K5/6x86 processor due to possible overheat.
The P55-TV supports minimum of 8MB of System Memory and maximum of
128MB while L2 Cache can be 256KB/512KB synchronous SRAM Onboard with
the COAST 2.1 "Cache-On-A-STick" solution to increase system performance.(
refer to Page 2-5 Cache Memory Configuration for the details.)
The P55-TV supports standard Fast Page, EDO (Extended Data Out or Hyper
Page Mode) or synchronous DRAM. The P55-TV provides four 72-pins SIMM
and one 168-pins DIMM sites for memory expansion. The socket support 1M x
32(4MB), 2M x 32(8MB), 4M x 32(16MB), and 8M x 32(32MB) single-sided or
double-sided memory modules. The memory timing requires 70 nS Fast page
devices or 60 nS EDO DRAM. Memory parity generation and checking is not
supported. (DRAM Modules may be parity[x 36] or non-parity[x 32].
The P55-TV supports Onboard two PCI IDE connectors, and detects IDE
harddisk type by BIOS utility automatic.
The P55-TV supports Award Plug & Play BIOS for the ISA and PCI cards. The
BIOS can be located in Flash EPROM. The advantage of having Flash EPROM is
much easier to replace BIOS code if necessary.

P55-TV
2-5 Integrated PCI Bridge
The P55-TV utilizes Intel's 430VX PCIset chipset to support Intel Pentium
Processor PCI/ISA system. The Intel 82430VX PCIset chipset consists of the
82437VX system controller (TSC), two 82438VX Data Path (TDP) devices, and
one 82371SB PCI ISA/IDE Accelerator (PIIX3) bridge chip. It provides an
interface which translates CPU cycle into PCI bus cycle, and PCI burst read/write
capability. In addition, it provides high performance PCI arbitor to support four
PCI Masters, Rotating Priority Mechanism, and Hidden Arbitration Scheme
Minimizes Arbitration Overhead.
There are four interrupts in each PCI slot : INTA#, INTB#, INTC#, and INTD#.
Since the P55-TV adapts the PCI auto-configuration with the system BIOS Setup
utility. When the system is turned on after adding a PCI add-in card, the BIOS
automatically configure interrupts, DMA channels, I/O space, and other
paramaters. You do not have to configure jumpers or worry potential resource
conflicts. Because PCI cards use the same interrupt resource as ISA cards, you must
specify the interrupt used by ISA add-in cards in the BIOS Setup utility.
If however, a "Legacy card" (such as plug paddle card and cable into the ISA slot.)
is plugged in the system, modification in the ROM SETUP UTILITY become
necessary. First, enter PCI CONFIGURATION SETUP utility from ROM
SETUP UTILITY main menu to set the "PCI IDE IRQ MAP TO : ISA".
Secondly, you must enter CHIPSET FEATURES SETUP UTILITY from ROM
SETUP UTILITY main menu and set the " Onboard Primary PCI IDE: Disabled
and Onboard Secondary PCI IDE: Disabled." When you plugg the PCI/ISA IDE
card into the system, You should Disabled Onboard Primary and Secondary PCI
IDE from CHIPSET FEATURES SETUP UTILITY too.
Some "Legacy card" ( no paddle card and cable.) you can set the system interrupt
request (IRQ) on the "Legacy card" (refer to user's manual of the card) to a proper
system IRQ level (in general, card's Primary assigned to INTA and Secondary
assigned to INTB). If the card is plugged into slot 1(marked PCI#1), you can not
use second slot (marked PCI#2) because the Secondary INT signal takes INTB
from the slot (refer to Page 3-12 for circuit diagram). The user then enter PCI
CONFIGURATION SETUP utility from ROM SETUP UTILITY main menu
and set the "PCI IDE IRQ MAP TO : PCI-Slot 1" (depend on the slot # where the
Legacy card is plugged).

AWARD BIOS Setup
Award's ROM BIOS provides a built-in Setup program which allows user to modify the
basic system configuration and hardware parameters. The modified data will be stored
in a battery-backed CMOS RAM so data will be retained even when the power is turned
off. In general, the information saved in the CMOS RAM stay unchanged unless there
is a configuration change in the system, such as a hard drive replacement or a new device
installment.
It is possible for the CMOS battery to fail. This will cause data lose in CMOS only.If
this does happen you will need to reconfigure your configuration parameters.
To enter Setup Propgram
Power on the computer and press <Del> key immediately . This will bring you into BIOS

Note: When the computer enters the suspend mode (setting the suspend mode
valid range from 1 minute up to 1 hour) activated by the BIOS Power Management, you need to RUN a program POWER.EXE under DOS root, or need to
add DEVICE=C:\DOS\POWER.EXE in your CONFIG.SYS. This will keep the
system time updating normally when the system wake up from the suspend

mode. The supend mode for Windows 95 or windows 3.1x must have windows
APM feature installed. Choose "Advanced Power Management" item from
"system device". The "system device" field was from "system" icon in the
"control panel."
3-4-1 The Description of the Power Management
A. Power Management mode selection :

: The system operates in NORMAL conditions (Non-GREEN)
and the Power Management function is disabled.
Max. saving: This mode will maximize the power saving capability.
Min. saving: This mode will minimize the power saving capability.
User Define: Allows user to define time-out parameters to control the power saving
mode. Refer to item B shown below.
AWARD BIOS 3-9
B. Time-out parameters :
HDD Standby
HDD Standby timer can be set from 1 to 15 minute(s).
System Doze
The "System Doze" mode timer starts to count when there is no "PM events"
occurred. The valid time-out setting is from 1 minute up to 1 hour.
System Standby
The "Standby" mode timer starts to count when "System Doze" mode timer timed
out and no "PM events" occurred. Valid range is from 1 minute up to 1 hour.
System Suspend
R
This function works only when the Pentium Procssor is installed.The timer starts
to count when "System Standby" mode timer is timed out and no "PM Events"
occurred. Valid range is from 1 minute up to 1 hour.
3-4-2 Description of the Green Functions
The P55TV2 supports HDD Power Down, Doze and standby power saving functions
when Intel PentiumR Processor is installed. In addition, the suspend function
is supported when the J2's sleep (refer to Figure1-1) is closed to enter the green function.
The detailed descriptions of these functions are provided in the next page.
HDD Power Down
When system stop reading or writing HDD, the timer starts to count. The system will
cut off the HDD power when timer runs out of time. The system will not resume
operation until either a read from or a wirte to HDD command is executed again.
Doze Mode
The system hardware will drop down CPU clock from nomal working speed
when Doze mode time-out occurs
Standby Mode
When the system standby mode timer times-out, it will enter the standby mode and
retain CPU at slow working speed. The screen will be blanked out.
Suspend Mode
When the system suspend timer times-out, the system will enter the suspend mode
and the chipset will stop CPU clock immediately. The power consumption in
Suspend Mode is lower than in standby mode. The screen is also blanked out.
3-10 CHAPTER 3
PM Events:
AWARD BIOS defines 15 PM Events in the power management mode (Doze,
standby & suspend). The user can initialize any PM Events to be "Enable" or "Disable".
When the system detects all of the enabled events, do not have any activity. It will
start the system Doze timer first if the "Power Management" is not "Disabled". Once
the system Doze timer is timed out, it will process doze power saving procedure
by starting the system standby timer. When the standby timer run out and all of the
"Enabled" events remains silent, the system will enter the standby mode. By now, the
system will not only process the standby power saving procedures but also start the
system suspend timer. When the suspend timer times out, all of the CPU clock will
stop by dropping system clock down to zero and remains this way until any one
of the "Enabled" event occurrs.

Resource Controlled By:The default value is Manual.
Manual: The PNP Card's resource will be controlled manually. You can set which
IRQ-X and DMA-X are assigned to PCI/ISA PNP or Legacy ISA Cards.
Auto: If your ISA card and PCI card are all PNP cards, BIOS will assign the inter
rupt resource automatically.
AWARD BIOS 3-11
Reset Configuration Data:The default value is Disabled.
Disabled: Normal Setting.
Enabled : If you had plugged some Legacuy cards in the system and they were
recorded into ESCD(Extended System Configuration Data), you can set this
field to Enabled to clear ESCD.
PCI IDE IRQ Map To: The default value is PCI-AUTO
When you have true PCI card(s) plugged into the system, you will not need
to change any thing here in the SETUP program. However, if you do not
know whether you have true PCI card or not, please refer to your PCI card
user's manual for the details.
When you have a Legacy card (describbed in section 2-6) to be plugged
into the system,a proper setting is extremely important or it may cause the
system hang. The diagram shown below tells you how the Rotating
Priority Mechanism is designed.
Used MEM base addr and Used MEM Length : The default value is N/A.
The Used MEM base addr (CB00, CC00, D000, D400, D800,
DC00)and Used MEM Length (8K, 16K, 32K, 64K)were to support some
specific ISA Legacy cards with requested memory space below 1M
address. Now with these two functions, users can define where the used
memory address is located and its length of the legacy area that is wsed
by the legacy device to avoid the memory space confilict. For example, if
users select "D000" for "Used MEM base addr" and "16K" for "Used
MEM Length," that means the address region D0000H-D3FFFH is
occupied by ISA legacy cards, and thus BIOS will not assign this region
for PnP/ISA and PCI cards.

NOTE: HDD Modes
The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE

Generic access mode in which neither the BIOS nor the IDE controller will
make any transformations during accessing.
The maximum numbers of cylinders, heads & sectors for NORMAL mode are
1024, 16 & 63.

528 Megabytes
If user sets his HDD to NORMAL mode, the maximum accessible HDD size
will be 528 Megabytes even though its physical size may be greater than that!
AWARD BIOS 3-17
LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the
528 Megabyte 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 Gigabytes which is obtained by
the following formula:
no. Cyclinder
(1024)
x no. Head
( 255)
x no. Sector
( 63)
x bytes per secttor
( 512)
8.4 Gigabytes
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 does 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 nultiplied by 2. A reverse
transformation process will be made inside INT 12h in order to access the right
HDD address!

Note:
To support LBA or LARGE mode of HDDs, there must be some softwares involved.
All the software is located in the Award HDD Service Routine (1NT 13h). It may
fail to access a HDD with LBA (LARGE) mode selected if you are running under
an Operating System which replaces the whole 1NT 13h. UNIX operating systems
do not support either LBA or LARGE and must utilize the Standard mode. UNIX
can support drives larger than 528MB.
