I try to modified your dump bios file,maybe you can rewrite it and test. I use a hot air desolder and solder it again. So if we want to modify the intel bios,we need direct read data from chip,after modified we rewrite to chip again. The bio file we download from intel official webpage, i think it seem contain many fake and protect ,and when i modify it any ,it will not pass flash utility check(windows update package,else) ,it cann't flashing correctly.

Don't know if that's possible, but I figured it was worth an ask! Thanks!

We need some way to 'decompress' my dump so the microcode can be easily updated, or we need an alternative way to update it directly. Which is not obviously updatable, at least not with donovan6000's guide. So I took the 1 MB dump and tried to modify that with the same procedure, but I guess the BIOS is all compressed? The microcodes are there, but where I was expecting headers like:Ġ1 00 00 00 07 0A 00 00 08 20 09 04 7A 06 01 00Ġ0 68 00 00 E0 00 EB 4C 81 7D F8 7A 06 01 00 72 I quickly found that, whoops, the BIOS chip is a standrd 8 megabit/1 MB thing, but Intel's BIO file was over 3 MB-it had a bunch of other stuff going on with it. So I bought a CH341A programmer and SOP-8 test clips to interface with the BIOS chip directly, to bypass the official tools. I updated the microsode in Intel's provided BIO file as described in that guide, but as semi-expected, none of the official BIOS flashing utilities accepted my mod. Delidded's guide said that 'Intel may be using a secure checksum to prevent people from modifying ', but I gave it a shot anyway with donovan6000's Insyde BIOS guide. The microcode in the BIOS is from 2008, so I thought updating it to the latest stuff might help. I guess this is an issue of 'CMPXCHG16b / CompareExchange128 not being supported'. Potential donor BIOS: ASUS P5G41T-M LX2/GB (same chipset, and it has the latest 771 microcode) Also, if a 'restart' command is issued from anywhere, either from Windows, Linux, or even the BIOS setup, it'll reboot into nothing, forcing me to do a hard reset.ĬPU spec code: SLBBR (I also tested it with a SLBBM, same problems) 32-bit Windows boots, and Linux seems fine. It POSTs fine, but 64-bit Windows will not boot. My Aida64 screenshot. This screenshot is from my current setup with a 775 CPU, so I'm not sure if it's of much use.Ĭurrent problems: I'm trying to use a 771 CPU with it.
