>> What is INTEL IOTG support?Never mind, I wanted to say that INTEL will not support Penryn, either Merom, or Nehalem (over 9 years in production).

Yes, you can. Ether using source code, but other that that (if you have some sort of problems), you just need to find it in Coreboot .rom file the proper place (WBINVD is 0F 09 opcode, while INVD is just 0F 08)! ;-)

As you have said/wrote, higher FREQ could be the showstopper. Above written (with INVD) is also good enough as canary test. :-)

Ahhhhh... I missed this part over the years!?!? So, there is Open Source initram code, but for very old CORE families (0 - pre CORE, 1 and some 2s). Thank you for enlightening me.
>>So I will soon try to confirm this theory with 533MHz fsb cpu.
I look forward/am interested to hearing from you (if you also do extras for 667MHz with INVD, Full House)! :thumb up:
Thank you,
