Hardware design
2-1 Overview The P55TV2 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 provides 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, CD-ROM device, etc). The PnP Ultra I/O controller provides the standard PC I/O functions including: floppy interface, two 16 Byte FIFO serial ports and one EPP/ECP capable parallel port. The
P55TV2 layout is shown in the previous page for user's reference. Care must be taken when inserting memory modules, inserting CPU or even plugging PCI card into
the associated slots to avoid damaging any circuits or sockets on board. A cooling fan is strongly recommended when installing P54C/P54CTB/P55C/K5/K6/6x86/6x86L processor due to possible overheat.
The P55TV2 supports a minimum of 8MB of System Memory and a maximum of
128MB while L2 Cache can be 256KB/512KB synchronous SRAM Onboard to increase system performance (Refer to Page 2-10 Cache Memory Configuration for the details).
R
The P55TV2 supports standard Fast Page, EDO (Extended Data Out or Hyper Page
Mode) or synchronous DRAM. The P55TV2 provides four 72-pin SIMM and two 168-pins DIMM sites for memory expansion. Each socket supports 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 are not supported. (DRAM Modules may be parity[x 36] or non-parity[x 32].
The P55TV2 supports Onboard two PCI IDE connectors, and BIOS detects IDE harddisk type automatically.
The P55TV2 supports Award Plug & Play BIOS for ISA and PCI cards. The BIOS is located in Flash EPROM which is a technology to easily revise/upgrade BIOS through software.
The P55TV2 has been designed with Baby AT form-factor. The mainboard layout is shown in Figure 1-1.

2-6 Integrated PCI Bridge
Hardware Design 2-11
The P55TV2 utilizes Intel's 430VX PCIset chipset to support Intel Pentium Proces-
R
sor PCI/ISA system. The Intel 82430VX PCIset chipset consists of one 82437VX system controller (TVC), 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 arbiter or supports four PCI Masters, Rotating Priority Mechanism, and Hidden Arbitration Scheme Minimizes Arbitration Over­head. The 82371SB(PIIX3) supports PCI Specification Revision 2.1 Compliant and contains a Universal Serial Bus interface with both host and hub control functions. The P55TV2 reserves USB connector to provide two USB ports for serial transfer at 12 or 1.5 Mbit/sec. This will supports legacy keyboard and mouse software with USB-Base Keyboard and mouse.
There are four interrupts in each PCI slot : INTA#, INTB#, INTC#, and INTD#, since the P55TV2 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 about potential resource conflicts. Because PCI cards use the same interrupt resource as ISA cards, you must specify the interrupts used by ISA add-in cards in the BIOS Setup utility.
If a "Legacy card" (such as paddle card and cable) is plugged into the ISA slot the following modifications 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".
Second, 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.
you can set the system interrupt request (IRQ) on some "Legacy cardswhich have no paddle card and cable" (refer to user's manual of the card) to a proper system IRQ level (In general, the card's Primary is assigned to INTA and Secondary is assigned to INTB). If the card is plugged into slot 1(marked PCI#1), you cannot 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 enters PCI CONFIGURATION SETUP utility from ROM SETUP UTILITY main menu and sets 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.

Note: The Security Option contians "setup" and "system". The "setup" indicates
that the password setting is for CMOS only while the "system" indicates the password setting is for both CMOS and system boot up.
Virus Warning: This category flashes on the screen. During and after the system boots up, any attempts to write to the boot sector or partition table of the hard disk drive will halt the system and an error message will appear. You should then run an anti-virus program to locate the virus. Keep in mind that this feature protects only the boot sector, not the entire hard drive. Default value is Disabled Enabled : Activate automatically when the system boots up causing a warning
message to appear when any attempts to access the boot sector or the hard disk partition table.
Disabled: No warning message to appear when any attempts to access the boot
sector or the hard disk partition table.
CPU Internal Cache / External Cache: These two categories speed up memory access. However, it depends on CPU/chipset design. The default value is Enabled. If your CPU is without Internal Cache then the item "CPU Internal Cache" will not show.
Enabled: Enable cache. Disable : Disable cache.

3-4-1 The Description of the Power Management
A. Power Management mode selection :
Disabled : 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.
Page 22
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
This function works only when the Pentium Procssor is installed. The timer starts
R
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 Pentium 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.
R
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.
Page 23
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.
3-5 PnP/PCI CONFIGURATION
The PnP/PCI configuration program is for the user to modify the PCI/ISA IRQ signals when various PCI/ISA cards are inserted in the PCI or ISA slots.

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.

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.

The "IDE HDD AUTO DETECTION" utility is a very useful tool especially when you do not know which kind of hard disk type you are using. You can use this utility to detect the correct disk type installed in the system automatically. But now you can set HARD DISK TYPE to Auto in the STANDARD CMOS SETUP . You do not need the "IDE HDD AUTO DETECTION" utility. The BIOS will Auto-detect the hard disk size and model on display during POST.

NOTE: HDD Modes
The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL mode. 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.
no. Cyclinder (1024) x no. Head ( 16) x no. Sector ( 63) x no. per sector ( 512) 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!
Page 30
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:
CYLS. HEADS SECTOR MODE 1120 16 59 NORMAL 560 32 59 LARGE
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!
Maximum HDD size:
no. Cyclinder (1024) x no. Head ( 32) x no. Sector ( 63) x bytes per sector ( 512) 1 Gigabytes
Page 31
3-18 CHAPTER 3
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.
