LGA771 Bios Microcode for HP dc7800 sff

1. Download and flash BIOS 1.28

Install old CPU, boot from USB stick with DOS and run FlashBin.exe.
3. Reboot and make BIOS backup again.
 
Same effect. BIOS ROM is currupt. I think HP inject protection mechanism in BIOS. I'll try tomorrow flash your version of BIOS by CH341A. It's difficult because first i must desolder eeprom  (soldered eeprom on M/B not to read, maybe protection by HP too) then flash and solder it back.

Did you delete my "corrupt" mod from flash (files: 7F1_0135.bin & flsh.cpu)? You need to use my previous patch with name 786F_771_1067A.zip
Don't use my mod with CH341A!

Hi. I did not succeed. I have modified original ROM 1.35, erase any microcodes exept 1067A plat 2,6 and flash it by CH341A. PC start with normal CPU-fan speed, but after mem check and saving coniguration PC restart and have same result (black screen and full speed CPU fan).

OK. I still need a result of tests with BIOS 1.28 and my previous patch (786F_771_1067A.zip).

Can't downgrade BIOS from 1.35 to 1.28, 1.24 or 1.04. Any attempt to flash BIOS to version lower then 1.35 has BootBlock Emergency Recovery Mode screen. I take BIOS ROMs from HP site, and i don't understand, why this ROMs is corrupted? Do you have ideas, how to downgrade BIOS version without using CH341A, because i'm afraid, if i desolder EEPROM one more time, contact pads will break?

OK. I take same motheboard from other dc7800 sff with BIOS ver. 1.04, and upgrade to BIOS ver. 1.28 Then i flash your microcode patch, but it not take effect, still same result - with X3363 CPU after reboot have black screen and full speed CPU fan.

OK. This updated microcode for current CPU only. See offset = 0x260000.
Please try my new mod for BIOS 1.35 on your first motherboard.
