Update, i think i figured it out, after finally found the correct bin file, which is IS7G_24.BIN. The motherboard has bios write protection on it. both Uniflash (ver 1.4) and AWDflash (ver 8.59) gave me the similar bios protection error unable to write the current bios, there's no way of disabling it in the bios settings (nowhere to be found at all) and no pins on board to disable it, the only way i can flash the bios is with ch341a programmer to flash the bios chip itself. i already ordered it. it's very cheap and backup my original bios, so hopefully this will work.

The .exe you can download from The Retroweb includes a version of Awardflash along with the BIOS .bin. I've come to prefer BIOS updates that include the flash utility since it avoids the potential extra layer of difficulty of having to find the exact version of the flash utility you need.

i did after figure out how to extract the bin and awdflash exe (thanks to Retroweb), the probelm was the bios write protection was enabled on the board (and both Uniflash and Awdflash failed to flash the bios), and it's almost impossible to disable the bios write protection with IS7 board (my model is the plain IS7, not IS7-E or IS7-G), no pins on the board to disable it, no missing pins to solder, no option in the bios menu, the only way i can flash the bios is by using a tool for the bios chip itself.

My mistake, I assumed the difficulty was not having the correct flash utility. I recently encountered that when updating the BIOS on my A8N SLI Premium and I solved it by looking at one of the images in the manual that showed the version of Awardflash, then finding that particular version.

That write protect sounds frustrating, why do you suppose that is? Was this board for some sort of OEM application do you think?

i have no idea. it doesn’t look like a OEM board, i got it off eBay few months ago for 38£, a good deal consider abit socket 478 boards are becoming expensive, the reason i got good price was because it was pretty dusty and had a lot of bulging caps, but it came with the I/O shield. after got it cleaned and recapped it works great. but i bugs me that was unable to flash the latest bios. i bought ch341a programmer tool, hopefully i will be able to flash it directly to the bios chip itself.
