Hello everyone.
Until yesterday, I was running an overclocked Core2Duo E6750 on a Abit IP35 pro mainboard (LGA 775, P35 chipset, latest BIOS). I love my setup and wanted to give it a little boost using a Core2Quad when I read about the Xeon mod which would allow me to install a LGA 771 Xeon on a LGA 775 board. So I checked the compatibility on www.delidded.com, ordered a pre-modded Xeon on ebay, cut off the tabs from socket 775, installed the Xeon, reset the BIOS and booted the system and voilà, works like a charm. My CPU benchmark scores doubled and I was very pleased with the result.
So I continued tweaking my BIOS. That was the when I started noticing that any changes done in the µguru tab were omitted. Even simple changes like fanEQ control didn't work. Everytime I changed anything in the µguru tab, and exited saving, the computer would shut down, start, (as it always does), but then shut down again, start again and everyhing in the µguru tab was reset. Any other changes in the BIOS, however, were saved.
I googled but could only find the note on www.delidded.com saying
So I checked my BIOS dump for the Xeon microcode with "intelmicrocodelist.exe", and noticed that it contained my cpuid (10676 for SLANQ). I patched the BIOS-file anyways with CBROM195, but no changes were applied to the microcode list. So I didn't flash the patched BIOS file. (Q: Are there maybe any other changes made when adding the microcode that I don't see? Is the microcode only a list of supported CPUs or are there any infos embedded that tell the BIOS how to "deal" with the CPU?)
I failed trying to flash the beta BIOS v.20 from https://soggi.org/motherboards/abit.htm, with awdflash.
I would appreciate any help on the matter.
