Hardware Design 2-1 Chapter 2 Hardware design 2-1 Overview The EP-5ATXA-M is designed with Intel 82430TX PCIset chipset which is developed by Intel Corporation to fully support Pentium ProcessorRPCI/ISA system. The Intel 82430TX PCIset chipset can increase integration and improve 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).
2-2 EP-5ATXA-M The EP-5ATXA-M 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. The EP-5ATXA-M has been designed with ATX form-factor with ATX power connector. The mainboard layout and system block diagram are shown in Figure 1-1 and Figure 2-1.

2-10 EP-5ATXA-M When you have a DIMM module to plug into a 168-pin dual readout connnector, you must make sure that the DIMM module is 3.3V/Unbuffered to supports Intel PentiumRProcessor System. * EP-5ATXA-M Supports and extends many memory configurations on its 2 SIMM and 2 DIMM sites. The memory size of any configuration can be combined flexibly. BIOS will detect your memory configurations and sizes automaticallly. * The 70ns Fast Page Mode or 60ns EDO is necessary.
Hardware Design 2-11 2-6 Integrated PCI Bridge R The EP-5ATXA-M utilizes Intel 430TX PCIset chipset to support Intel Pentium Processor PCI/ISA system. The Intel 82430TX PCIset chipset consists of one 82439TX system controller (MTXC) and one 82371AB PCI ISA/IDE Accelerator (PIIX4) bridge chip. It provides an interface which translates CPU cycle into PCI bus cycle and PCI burst read/write capability.
Introduction 3-1 Chapter 3 ATX Form-Factor Overview The EP-5ATXA-M is base on ATX form-factor with a board size 8.2" x 12" (208mm x 305mm). The ATX from-factor is essentially an enlarged baby-AT basedboard rotated 90 degrees within an ATX chassis and uses ATX power supply. The changes make pentium R processor able to locate away from the expansion slots and all onboard I/Os able to hold full length add-on cards.
3-2 EP-5ATXA-M The EP-5ATXA-M is equipped with a standard I/O back pannel featuring a serial port, PS/2 mouse port, PS/2 keyboard port, parallel port, and secondary serial port (refer to Figure 3-2 ). Figure 3-2: EP-5ATXA-M I/O back panel Layout The EP-5ATXA-M supports ATX power connector which is a single 20-PIN input device for ATX power supply (see Figure 3-3).
Introduction 3-3 3-1 External Modem Ring-in Power ON and Keyboard Mouse Power ON Functions External Modem Ring-in Power-ON Function On the basis of bounded functions in I/O chipset, the two serial ports are able to support the External Modem Ring-in Power ON function. Once users connect the external modem to COM1 or COM2, the EP-5ATXA-M mainboard allows them to turn on their system through the remote and host's dial-up control.
AWARD BIOS 4-1 Chapter 4 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 hard drive replacement or new equipment change.
4-2 CHAPTER 4 4-1 Standard CMOS Setup Choose "STANDARD CMOS SETUP" in the CMOS SETUP UTILITY Menu (Fig.4-1). 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.

AWARD BIOS 4-9 4-4 Power Management Setup Choose the "POWER MANAGEMENT SETUP" in the CMOS SETUP UTILITY to display the following screen. This menu allows users to modify the power management parameters and IRQ signals. In general, these parameters should not be changed unless it is absolutely necessary. ROM PCI/ISA BIOS (2A59IPAB) POWER MANAGEMENT SETUP AWARD SOFTWARE, INC.
4-10 CHAPTER 4 B. Time-out parameters : HDD Standby The HDD Standby timer can be set from 1 to 15 minute(s). System Doze The "System Doze" mode timer starts to count when no "PM event" occurres. The valid time-out setting is from 1 minute up to 1 hour. System Standby The "Standby" mode timer starts to count when the "System Doze" mode timer times out and no "PM events" occurre. The valid range is from 1 minute up to 1 hour. System Suspend R This function works only when the Pentium Procssor is installed.
AWARD BIOS 4-11 MODEM Use IRQ: Name the interrupt request (IRQ) line assigned to the modem (if any) on your system. Activity of the selected IRQ always awakens the system. Default is IRQ 3. N/A: No IRQ is used. 4: IRQ 4 7: IRQ 7 10: IRQ 10 3: IRQ 3 5: IRQ 5 9: IRQ 9 11: IRQ 11 The KP6-LA supports HDD Power Down, Doze and Standby power saving functions when using the Intel Pentium II Processor.

Disabled: The system cannot use remote ring in to wake system up. Power Loss Recovery: If the power to the system is cut off the system will turn itself back on with no user intervention. The default is Enabled. Enabled: The system will power back on after a power interuption.
AWARD BIOS 4-13 The EP-5ATXA-M supports HDD Power Down, Doze and standby power savingfunctions when Intel Pentium RProcessor is installed. In addition, the suspend function is supported when the JP14's sleep (sleep ref. 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 the system stops reading or wiriting HDD, the timer starts to count. The system will cut off the HDD power when timer runs out of time.
4-14 CHAPTER 4 ROM PCI/ISA BIOS(2A59CPA9) PNP/PCI CONFIGURATION AWARD SOFTWARE, INC.
AWARD BIOS 4-15 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) 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 corresponding.

4-20 CHAPTER 4 4-9 IDE HDD Auto Detection 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 don't need the "IDE HDD AUTO DETECTION" utility. The BIOS will Auto-detect the hard disk size and model on display during POST.
AWARD BIOS 4-21 LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the 528 Megabyte bottleneck. The numbers of cylinders, heads and sectors shown in the setup may not be the numbers physically contained in the HDD. During HDD accessing, the IDE controller will transform the logical address described by sector, head and cylinder into its own physical address inside the HDD. The maximum HDD size supported by LBA mode is 8.4 Gigabytes which is obtained from the following formula: no.
4-22 CHAPTER 4 Note: 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 (1NT 13h). It may be failed 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. However UNIX can support drives larger than 528MB.
