Current BIOS has microcode for Core 2 Extreme QX6700: version - 0x6A, date - 10/02/2010.
But BIOS has block for this CPU.
I have not any tool compatible with this format of BIOS. I can unpack it only (by hpdeco).
I've found that checking in HPBIOS.00B module.

Well. Have you a hardware programmer (e.g. CH341A) to recover BIOS in bad cases?
