This section allows users to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and accesses to system memory resources, such as DRAM and the external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for the system.

DRAM Timing Selectable

The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if the system had mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the data held in the slower memory chips.

CAS Latency Time

When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. The Choice: 1.5, 2, 2.5, 3.

DRAM Cycle Time Tras/Trc

Select the number of SCLKs for an access cycle. The choice: 5/7, 6/8.

Item Help _______________________ Menu Level ¾

DRAM RAS# to CAS# Delay

• This field lets users insert a timing delay between the CAS and RAS strobe

signals.

• It is used when DRAM is written to, read from, or refreshed.

• Choice 2 means shorter delay which shortens the process of charging; and

choice 3 means longer delay which lengthens the process of charging.

• This field applies only if the synchronous DRAM is installed in the system.

The choice: 2, 3.

DRAM RAS# Precharge

If an insufficient number of cycles are allowed for the RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system.

The choice: 2, 3.

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. The choice: Enabled, Disabled.

4.14 Supervisor/User Password Setting

The user can set the password for either supervisor or user, or for both of them.

Supervisor password: for entering and changing the settings of the system

User password: for just entering the system but does not have the privilege to

change any settings of the system

If this function is enabled, the following message will appear to guide the user to create a password.

ENTER PASSWORD:

Type the password, up to eight characters in length, and press <Enter>. The password typed now will clear any previously entered password from CMOS memory. The user will be asked to re-type the password, and press <Enter>.

Note: The user may press <Esc> to skip the selection and not to enter a password.

To disable a password, just press <Enter> when prompted to enter the password. Once the password is disabled, the system will boot and the user can enter Setup freely.

PASSWORD DISABLED:

When a password has been set, the user will be prompted to enter it every time when entering Setup. This prevents an unauthorized user from changing any part of the system configuration.

Additionally, when a password is set, the user can also require the BIOS to request a password every time the system starts. This would prevent any unauthorized use of the computer.

The user determines when the password is required within the BIOS Features Setup Menu and its security option (see Section 3). If the security option is set to “password”, then it will be required both at boot and at entry to Setup. If it is set to “Setup”, the password is needed only when trying to enter Setup.

4.15 Exit Selecting

Save & Exit Setup

Pressing <Enter> on this item asks for confirmation:

Save to CMOS and EXIT (Y/N)? Y

Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after the system has been turned off. When the computer reboots again, the BIOS configures the system according to the Setup selections stored in CMOS.

Exit Without Saving

Pressing <Enter> on this item asks for confirmation:

Quit without saving (Y/N)? Y

This allows the user to exit Setup without saving any changes in CMOS. The previous selections remain in effect. This exits the Setup utility and restarts the computer.

Appendix A Watchdog Timer

The Watchdog Timer is provided to ensure that standalone systems can always recover from catastrophic conditions that cause the CPU to crash. This condition may have occurred by external EMI or a software bug. When the CPU stops working correctly, hardware on the board will either perform a hardware reset (cold boot) or a Non-Maskable Interrupt (NMI) to bring the system back to a known state.

A BIOS function call (INT 15H) is used to control the Watchdog Timer:

INT 15H:

AH – 6FH

Sub-function:

AL – 2 : Set the Watchdog Timer’s period BL : Time-out value(Its unit--second or minute, is dependent on the item “Watchdog Timer unit

select” in CMOS setup).

The sub-function 2 needs to be called to set the time-out period of Watchdog Timer first. If the time-out value is not zero, the Watchdog Timer will start to count down. While the timer value reaches zero, the system will reset. To ensure that this reset condition does not occur, the Watchdog Timer must be periodically refreshed by calling sub-function 2. However the Watchdog timer will be disabled if the user set the time-out value to zero.

A tolerance of at least 10% must be maintained to avoid unknown routines within the operating system (DOS), such as disk I/O that can be very time-consuming.

Note: when exiting a program, it is necessary to disable the Watchdog Timer; otherwise the system will reset.

Example program:

; INITIAL TIMER PERIOD COUNTER

; W_LOOP:

MOV AX, 6F02H ;setting the time-out value MOV BL, 30 ;time-out value is 48 seconds INT 15H ;

Appendix C How to Upgrade a New BIOS

Note: Before flashing BIOS, please enable the item “FLASH BIOS” in BIOS setting.

The user can install an upgrade BIOS for the SAGP-845EV download from the manufacturer’s web site (http://www.ieiworld.com support for new peripherals, improvements in performance or fixes to addressed known bugs.

BIOS Update Procedure:

1. Make a boot disk. Go to the DOS command prompt in MS-DOS or Windows 9x and, with an available floppy disk in "A", type "format A: /s" That will format the floppy and transfer the needed system files to it.

Note:

A. This procedure will erase any prior data on that floppy, so please proceed

accordingly.

B. Typically four files will be transferred, only COMMAND.COM being visible when

running a simple directory listing.

C. Please leave the diskette UN-write protected for the balance of this procedure.

2. Download the BIOS upgrade file and awdflash.exe utility from ICP web site to a temp directory on your hard drive, or directly to the floppy you made in step

3. Copy two files (BIOS file and awdflash.exe) to the boot floppy.

4. Reboot the system to the DOS command prompt using the boot diskette you just made.

5. At the DOS command prompt type, "awdflash filename.xxx", where filename.xxx is the file name of the BIOS file. Press enter.

6. Your first option, in sequence, will be to save the old BIOS. We recommend that you do that in case, for whatever reason, you decide you don't wish to use the new version once it is installed.

Note:

A. If you decide to save the old BIOS, PLEASE make sure you do NOT save it to

the same file name as the new BIOS - if you use the same BIOS name the old file will be written over the new file with NO warning prompt. A simple file name to save the old BIOS to is OLDBIOS.BIN.

B. If you do NOT decide to save the old BIOS, PLEASE at least write down the

version number of the old BIOS and store that information with your important computer documents. Enter N (for "no") and skip to step 9.

7. To save the old BIOS, press Y (for "yes").

8. Enter a name for the OLD BIOS file and hit enter.

Note: PLEASE be sure you do NOT save the old BIOS file to the same file name as the new BIOS - if you use the same BIOS name, the old file will write over the

). New BIOS may provide

new BIOS file WITHOUT a warning prompt. A simple file name for saving the old BIOS to is OLDBIOS.BIN.

9. Your second option, in sequence, will be whether you want to flash your BIOS. Enter Y (for "yes").

Note: This is the critical step. Once you kit the enter key, do NOT touch the keyboard, the reset button, or power switch while the flashing is in progress. There will be bar progressing across the screen while the flashing is progressing.

10. When the flashing process is complete, you will be asked to reset or power off the system. Remove the floppy diskette from the floppy drive and either hit the reset button or the power button.

11. Reboot the system and note that the BIOS version on the initial boot-up screen has changed to the new BIOS version. Your BIOS upgrade is now complete.

Recovering the previous BIOS:

1. Assuming you have the floppy made during the upgrade procedure noted above, boot the system with that diskette in the floppy drive. If you do not have floppy made during the upgrade procedure noted above, you will need to repeat steps 1 though 3 (above) for the version of the BIOS you wish to recover to.

2. Complete steps 4, 5, 6B, 9, 10, and 11 (above) substituting the name of the BIOS you wish to recover for the upgrade BIOS at step 5.
