»BIOS Update Utility
ASRUBIOS.EXE, ASRFLASH.BIN and UCODE.DAT: These are the Flash Memory Writer utility that updates the BIOS
by uploading a new BIOS file to the programmable flash ROM chip on the motherboard. To determine the BIOS version
of your motherboard, press <F2> to enter the BIOS setup utility during boot up, and check the BIOS version from the
Main menu. Larger numbers represent a newer BIOS file. This utility works only in pure DOS. And this utility is
included in the BIOS package. (How do I check the BIOS version?)
The Flash Memory Writer utility can not be suitable for all ASRock motherboards. Please use the Flash utility which is
included in each BIOS file to update its BIOS. Also ASRock motherboard MUST use ASRock's Flash utility to update
BIOS, those uncertified BIOS flashing tools will cause motherboard damage.
»Updating BIOS Procedures
1. Create a bootable system floppy disk and prepare a blank floppy disk.
2. Download the BIOS package (WinZip format with .zip file extension), unzip and save it to the blank floppy disk and you should see ASRUBIOS.EXE,
ASRFLASH.BIN, UCODE.DAT, BIOS file and README.TXT.
3. Boot from the disk you created in step 1 then switch to the floppy disk you created in step 2.
4. At the "A:" prompt, type ASRUBIOS, hit space bar once, and type BIOS file name then press <Enter>. For example: A:ASRUBIOS 75i65GV1.70
<Enter> then you will see a message "Please wait for loading BIOS ROM".
5. After about 1 minute, you will see the message "Flash ROM Update Completed - Pass", then you have finished upgrading the BIOS.
6. After finishing upgrading the BIOS, please remove the floppy disk. Restart your system and press <F2> to enter the BIOS setup utility during boot up.
7. In Exit menu, please select "Load Default Settings" and press <Enter> to continue.
8. Select "Exit Saving Changes" and press <Enter> to exit the BIOS setup utility.
9. Now, system is booting up with new BIOS.
»How do I check the BIOS version?
2.The BIOS version can be found in BIOS setup utility.
1.The BIOS version can be found during system boot up.
»Notice
If you encounter problems while updating the new BIOS, DO NOT turn off your system since
this corrupt BIOS might cause your system failed to boot up. Just repeat the process, and if the
problem still persists, update the original BIOS file. If the Flash Memory Writer utility was not
able to successfully update a complete BIOS file, your system may not be able to boot up. If this
happens, your system will need service.
