Hello overclockers! I was wondering if I could get your advice on a little problem I'm having. I recently flashed the latest (Version 3603 (Only for Win7 & Win8)) BIOS onto my Asus P8Z68-V PRO Z68 motherboard which caused system instability and a long POST time (90 seconds +), so I tried to flash an older version,version 0501, which has caused me to brick the BIOS (tried clearing the CMOS, wont even POST). I bought the motherboard in 09/2011, so assumed incorrectly version 0501 would be compatible, but am now thinking it probably wasn't, or maybe the flash process didn't work properly. Has anybody got any idea which BIOS would be best to use for that board released at that time?

• This is what you do. Download the Engineers version of AFUDOS attached here. Format a DOS-USB. Then place the AFUDOS.EXE file into your formated USB along with your ROM file. Restart and enter the DOS environment then enter these commands. AFUDOS /iXXXX.ROM /pbnc /n where xxxx= Rom.

After more research and a few downloads, I managed to get a special Engineering Edition of the AFUDOS tool which with a couple of extra command line parameters will allow an earlier build to be installed: AFUDOS /ixxxx.rom /pbnc /n where xxxx=name.rom. Running this version of the ROM update tool.

Also am I correct in thinking I can purchase a BIOS chip with a flashed BIOS on it, which may repair the motherboard? If that is not an option what would you recommend my best course of action would be?

Feb 15, 2016. Problem is, this far down the line, I can't seem to find the 'engineering edition' anywhere. I've made DOS bootable USBs using the HP tools with WIn 98 as well as with RUFUS and FreeDOS, and using AFUDOS 2.29ES and 3.36. I always get. ERROR: Unable to open ROM file I've downloaded the 0601.

I'm using a i7 2600k Processor if that makes any difference (I read there may have been issues with the latest BIOS due to an update to allow Ivy Bridge processors). Any help would be greatly appreciated. Thanks for your responses. I've found a replacement BIOS chip (cheers wazza). I flashed the latest BIOS from USB through the ASUS EZ Flash 2 utility.

I thought it all worked well, it completed the flash and then rebooted. Then it started to take ages to POST, around 90 seconds, and then eventually it would boot into Windows. When in windows it would just crash and explorer.exe just constantly locked up. I couldn't really be dealing with that so just ended up trying to downgrade the firmware, which I found out isn't possible with EZ flash 2, so then tried with AFUDOS engineering edition, via a Win98 USB start up disk. That didn't work either.

Eventually I found a way to force flash the BIOS at which point I was left with an unbootable computer. In retrospect it was stupid of me to force the flash, but the latest BIOS was so bad for me, I couldn't keep it. Lesson learnt though, I will definitely do some more research before doing that again. I'm just glad they have removable BIOS chips, absolute life saver, I thought I was going to have to shell out for a new motherboard and rebuild the PC which would have been a nightmare.
