Thinkpads Forum

It's possible? Now I'm workink with standard Pentium2 233MHz MMC-1 and when I changed to Celeron it didn't started
Some time ago I heard that I must change bios. But I didn't found what and how. Somebody can help me?

ps sorry my bad english - I'm not native english speaker :/

If I am not mistaken, you can only use Pentium II and maybe Pentium III, but not Celeron....the same as the 600Es.

With standard bios - You are right. But I wonder it is possible to patch bios to run with Celeron (something like upgrading cpu microcode in standard PC's bioses).
I tried to upload microcode of Celeron MMC-1 but it doesn't help.

I found that ThinkPad 390E is working with Celerons very good. If I'm not mistaken TP390E is similar to 390 but with MMC-2. Maybe swapping bios opcode helps? What are You thinking?
Somebody tried to do this?
