Chapter 1

Overview

The AX5T is a high-performance Pentium-based system board that utilizes the PCI/ISA architecture and ATX form factor. It integrates the Intel 82430TX PCIset, a Ultra I/O controller, and a PCI mode 4 enhanced IDE controller with bus master and Ultra DMA/33 to enhance system performance. It has 256KB or 512KB pipelined-burst second-level cache onboard and support four single in-line memory module (SIMM) plus two Dual in-line memory module (DIMM) that allow to mix EDO and SDRAM memory and expansion up to a maximum of 256MB. For the memory and IDE performance, the Intel 430TX chipset is currently the fastest Pentium chipset in the market.

Another feature that AX5T intends to implement is the Advanced Configuration Power Interface (ACPI). It introduces many new power management functions. The most attractive feature of ACPI for desktop user is probably OnNow, an idea from Notebook. You don't have to go through the entire boot process, into Win95, and back to your original work. Since ACPI specification is not fully defined yet. AX5T implements Suspend to Hard Drive by BIOS, from user point of view, it is the same as OnNow. Note that you have to use VESA compatible VGA (AOpen S3 PCI PV60/PT60), Sound Blaster compatible sound card (AOpen AW32/MP32), Rockwell compatible Modem (AOpen F34I/MP32) for Suspend to Hard Drive to work properly.

There are many user friendly features such as Modem Wake Up, RTC Wake Up Timer, Power Bottom Override. Refer to section 3.5 "Power management Setup" and Appendix B "Frequent Ask Question" for detail. Furthermore, AX5T uses 2M bit Flash ROM BIOS to reserve for future new functions.

AX5T has also passed FCC DoC test, this means you can use any kind of housing with very low EMI radiation.

Note: ACPI is a specification of PC97, it is not fully defined yet. Although Aopen will try the best to support ACPI (normally, through BIOS modifications), it is still possible AX5T can not fully comply ACPI specification.

2.2 Jumpers

Jumpers are made by pin headers and plastic connecting caps for the purpose of customizing your hardware. Doing so requires basic knowledge of computer hardware, be sure you understand the meaning of the jumpers before you change any setting. The onboard jumpers are normally set to their default with optimized settings.

On the mainboard, normally there is a bold line marked beside pin 1 of the jumper, sometimes, there are numbers also. If we connect (short) plastic cap to pin 1 and 2, we will say set it at 1-2, and when we say jumper is open, that means no plastic cap connected to jumper pins.

2.4 Configuring the System Memory

Pin 1 of

This mainboard has four 72 pin SIMM sockets (Single-in-line Memory Module) and two 168 pin DIMM socket (Dual-in-line Memory Module) that allow you to install system memory from minimum 8MB up to maximum 256MB.

Pin 1 of

The SIMM supported by this mainboard can be identified by 4 kinds of factors: ♦ Size: single side, 1Mx32 (4MB), 4Mx32 (16MB), 16Mx32 (64MB), and double

side, 1Mx32x2 (8MB), 4Mx32x2 (32MB), 16Mx32x2 (128MB).

♦ Speed: 60ns or 70ns access time ♦ Type: FPM (Fast page mode) or EDO (Extended data output) ♦ Parity: without parity (32 bit wide) or with parity (36 bit wide).

The DIMM supported by this mainboard are always 64-bit wide SDRAM. ♦ Size: single side, 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64

(64MB), 16Mx64 (128MB), and double side, 1Mx64x2 (16MB), 2Mx64x2 (32MB), 4Mx64x2 (64MB), 8Mx64x2 (128MB), 16Mx64x2 (256MB).

♦ Speed: normally marked -67, which means synchronous to maximum

67MHz.

♦ Parity: without parity (32 bit wide)

Because Pentium and Pentium Pro processor has 64 bit bus width, the four SIMM sockets are arranged in two banks of two sockets each, they are Bank0 and Bank1. Both SIMMs in each bank must be in the same size and type. It is allowed to have different speed and type in different bank, for example, 70ns FPM in one bank and 60ns EDO in another bank, in such case, each bank is independently optimized for maximum performance. The memory timing requires at least 70ns fast page mode DRAM chip, but for optimum performance, 60ns EDO DRAM is recommended.

2-20

Page 28

Hardware Installation

Warning: The default memory timing setting is 60ns to obtain the optimal performance. Because of the specification limitation, 70ns SIMM is recommended to be used only for CPU external clock 60MHz.

Tip: EDO DRAM is designed to improve the DRAM read performance. Unlike traditional fast page mode, that tristates the memory output data to start the precharge activity, EDO DRAM holds the memory data valid until the next memory access cycle, which is similar to pipeline effect and reduces one clock state.

There is no jumper setting required for the memory size or type. It is automatically detected by the system BIOS. You can use any single side SIMM and DIMM combination list below for BANK0/BANK1 or DIMM socket, and the total memory size is to add them together, the maximum is 256MB.

SIMM1 SIMM2 Subtotal of Bank0

None None 0MB 4MB 4MB 8MB 8MB 8MB 16MB 16MB 16MB 32MB 32MB 32MB 64MB 64MB 64MB 128MB 128MB 128MB 256MB

For double side memory module, there is one limitation. This mainboard supports only 4 RAS# (Row address latch) signals for DRAM control. They can only be occupied by one DRAM module, they can not be shared. The simple

rule is: If double side module at either Bank0 or DIMM1, the other must be empty, if you use double side at Bank0, DIMM1 must be empty. If you use at DIMM1, Bank0 must be empty. Bank1 and DIMM2 have the same limitation.

Double side module at either Bank0 or DIMM1, the other must be empty.

Double side module at either Bank1 or DIMM2, the other must be empty.

Single side SIMM at Bank0 Occupied Double side SIMM at Bank0 Occupied Occupied Single side DIMM at DIMM1 Occupied Double side DIMM at DIMM1 Occupied Occupied

Type and Location RAS2# RAS3#

Single side SIMM at Bank1 Occupied Double side SIMM at Bank1 Occupied Occupied Single side DIMM at DIMM2 Occupied Double side DIMM at DIMM2 Occupied Occupied

Caution: Make sure that you install the same SIMM type and size for each bank.

Caution: There are some old DIMMs made by EDO or FPM memory chip, they can only accept 5V power and probably can not fit into the DIMM socket, make sure you have 3.3V true SDRAM DIMM before your insert it.

Tip: If you have DIMM made by 3V EDO, it is possible that TX chipset can support it. But because it is so rare, the only 3V EDO DIMM had been tested by this mainboard is Micron MT4LC2M8E7DJ-6.

2-22

Page 30

Hardware Installation

Warning: Do not use SIMM and SDRAM DIMM together unless you have 5V tolerance SDRAM (such as Samsung or TI). The FPM/EDO operate at 5V while SDRAM operates at 3.3V. If you combine them together the system will temporary work fine; however after a few months, the SDRAM 3.3V data input will be damaged by 5V FPM/EDO data output line.

There is an important parameter affects SDRAM performance, CAS Latency Time. It is similar as CAS Access Time of EDO DRAM and is calculated as number of clock state. The SDRAM that AOpen had tested are listed below. If your SDRAM has unstable problem, go into BIOS "Chipset Features Setup", change CAS Latency Time to 3 clocks.

5V Tolerance

The driving capability of new generation chipset is limited because the lack of memory buffer (to improve performance). This makes DRAM chip count an important factor to be taking into consideration when you install SIMM/DIMM. Unfortunately, there is no way that BIOS can identified the correct chip count, you need to calculate the chip count by yourself. The simple rule is: By visual inspection, use only SIMM with chip count less than 24 chips, and use only DIMM which is less than 16 chips.

Warning: Do not install any SIMM that contains more than 24 chips. SIMMs contain more than 24 chips exceed the INTEL chipset driving specification. Doing so may result in unstable system behavior.

Warning: Although Intel TX chipset supports x4 SDRAM chip. Due to loading issue, it is not recommended to use this kind of SDRAM.

2-23

Tip: The SIMM/DIMM chip count can be calculated by following example:

1. For 32 bit non-parity SIMM using 1M by 4 bit DRAM chip, 32/4=8 chips.

2. For 36 bit parity SIMM using 1M by 4 bit DRAM chip, 36/4=9 chips.

3. For 36 bit parity SIMM using 1M by 4 bit and 1M by 1 bit DRAM, the chip count will be 8 data chips(8= 32/4) plus 4 parity chips(4=4/1), total is 12 chips.

4. For 64 bit DIMM using 1M by 16 bit SDRAM, the chip count is 64/16=4 chips.

Following table list the recommended DRAM combinations of SIMM and DIMM:

Warning: 64MB SIMMs using 16M by 4 bit chip (64M bit technology) are not available in the market and are not formally tested by AOpen quality test department yet. However they are supported by design specification from Intel and they will be tested as soon as they are available. Note that 64MB SIMMs using 16M by 1 bit chip (16M bit technology) have chip count exceed 24 and are strongly not recommended.

Tip: 8 bit = 1 byte, 32 bit = 4 byte. The SIMM size is represented by number of data byte (whether with or without parity), for example, the size of single side SIMM using 1M by 4 bit chip is 1Mx32 bit, that is, 1M x 4 byte= 4MB. For double side SIMM, simply multiply it by 2, that is, 8MB.

Memory error checking is supported by parity check. To use parity check you need 36 bit SIMM (32 bit data + 4 bit parity), which are automatically detected by BIOS.

Tip: The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred and this is called single bit error detection.

Chipset Features 8 Bit I/O Recovery Time

8 Bit I/O Recovery Time

1 2 3 4 5 6 7 8 NA

For some old I/O chips, after the execution of an I/O command, the device requires a certain amount of time (recovery time) before the execution of the next I/O command. Because of new generation CPU and mainboard chipset, the assertion of I/O command is faster, and sometimes shorter than specified I/O recovery time of old I/O devices. This item lets you specify the delay of 8-bit I/O command by count of ISA bus clock. If you find any unstable 8-bit I/O card, you may try to extend the I/O recovery time via this item. The BIOS default value is 4 ISA clock. If set to NA, the chipset will insert 3.5 system clocks.

Chipset Features 16 Bit I/O Recovery Time

16 Bit I/O Recovery Time

1 2 3 4 NA

The same as 16-bit I/O recovery time. This item lets you specify the recovery time for the execution of 16bit I/O commands by count of ISA bus clock. If you find any of the installed 16-bit I/O cards unstable, try extending the I/O recovery time via this item. The BIOS default value is 1 ISA clocks . If set to NA, the chipset will automatically insert 3.5 system clocks.

Chipset Features Memory Hole At 15M-16M

Memory Hole At 15M-16M

This mainboard implements AOpen special circuit (patent applied) to detect modem ring signal and wakeup from soft power off. The most possible applications are automatic answering machine and fax send/receive. It does not like traditional green PC suspend mode, the system can be true power off, (identified by the fan of your power supply is off). You can use external box modem or AOpen MP32/F34I internal modem card for modem ring-on, but MP32/F34I is recommended, since MP32/F34I has special circuit to cooperate with this mainboard and the modem power and system power can be off together. For detail of how to use modem ring-on, refer to section 3-17 "Modem Wake Up".

Power Management Suspend Mode Option

Suspend Mode Option

Power On Suspend Suspennd to Hard Drive

You can select suspend mode by this item. Power On Suspend is the traditional Green PC suspend

mode, the CPU clock is stop, all other devices are shut off. But power must be kept On to detect activities from modem, keyboard/mouse and returns the system to full power. The system activities is detected by monitoring the IRQ signals. Suspend to Hard Drive saves system status, memory and screen image into hard disk, then the power can be totally Off. Next time, when power is turned On, the system goes back to your original work within just few seconds. You need utility ZVHDD to reserve disk space. Refer to section 3.16 "Suspend to Hard Drive" for more information".

Clock Throttling means at the Doze/Standby state, the CPU clock count in a given time (not the frequency) is reduced to the ratio specified in this parameter. Actually, the period per CPU clock is not changed. For example, a 66MHz CPU clock remains the same 30ns clock period when system goes into Doze/Suspend. The chipset generates the STPCLK (stop clock) signal periodically to prevent CPU for accepting clock from clock generator. For full power on, the CPU can receive 66M count in one second. If the Slow Clock Ratio is set to 50%, the CPU will only receive 33M clock count in one second. This will effectively reduce CPU speed as well as CPU power.

If your ISA card is not PnP compatible and requires special memory space to support its function, specify the memory size in this parameter to inform the PnP BIOS to reserve the specified memory space for installed legacy ISA card.

3.7 Load Setup Defaults

The "Load Setup Defaults" option loads optimized settings for optimum system performance. Optimal settings are relatively safer than the Turbo settings. We recommend you to use the Optimal settings if your system has large memory size and fully loaded with add-on card (for example, a file server using double-sided 8MB SIMM x4 and SCSI plus Network card occupying the PCI and ISA slots).

3-27

Page 61

AWARD BIOS

Optimal is not the slowest setting for this mainboard. If you need to verify a unstable problem, you may manually set the parameter in the "BIOS Features Setup" and "Chipset Features Setup" to get slowest and safer setting.

3.8 Load Turbo Defaults

The "Load Turbo Defaults" option gives better performance than Optimal values. However, Turbo values may not be the best setting of this mainboard but these values are qualified by the AOpen RD and QA department as the reliable settings especially if you have limited loading of add-on card and memory size (for example, a system that contains only a VGA/Sound card and two SIMMs).

To attain the best system performance, you may manually set the parameters in the "Chipset Features Setup" to get proprietary setting. Make sure that you know and understand the functions of every item in Chipset Setup menu. The performance difference of Turbo from Optimal is normally around 3% to 10%, depending on the chipset and the application.

3.16 Suspend to Hard Drive

Suspend to Hard Drive saves your current work (system status, memory and screen image) into hard disk, and then the system can be totally power off. Next time, when power is on, you can resume your original work directly from hard disk within few second without go through the Win95 booting process and run your application again. If your memory is 16MB, normally, you need to reserve at least 16MB HDD space to save your memory image. Note that you have to use VESA compatible PCI VGA (AOpen PV60/PT60), Sound Blaster compatible sound card (AOpen AW32 or MP32) for Suspend to Hard Drive to work properly. Of course, we recommend to use AOpen products for best compatibility.

To use Suspen to Hard Drive:

1. Go into BIOS setup, Power Management Suspend Mode Option, select

Suspend to Drive.

2. Use utility ZVHDD to create a hidden file in your hard disk drive. This file is

used to save your system status and memory image. Just type:

C:>ZVHDD /c /file

3. Push suspend switch or use Win95 Suspend icon to force system goes

into Suspend to Hard Drive mode and then turn system power off by power switch of your power supply.

4. Next time you turn on your system, it will resume to your original work

automatically.
