for bios 2602 i think you have to disable the multiplier change thingy to see intel speed step. I did this several times and speed step would show up and i would disable it along with C1E but still can't change vcore. It still says "auto" as the only option. I just want to get to 3.6GHz!
Use afudos 2.17 in DOS to flash to 2403.
afudos /i2403.ROM /pbnc
Use a floppy drive or a usb stick with a boot sector on it. (google)
