Got subj currently working with Pentium 4 sl7z9, cpuid: 0F43.
Would like to run it with core 2 duo SLA4U, cpuid: 06F6. The mobo doesn't post with it. Tried adding 06F6's microcode to the bios with mmtool - no change.
Needing an advice and/or bios mod.
Attaching original bios.
The model doesn't have a hardware version supporting Conroe. So ASUS did'n make the newer BIOS to initiate Conroe properly. Adding new CPU microcode won't help. So , IMO , you'll bump into some issues even if your motherboard with pin-mod starts and shows a POST screen.
