Thinkpad T40 adding Dothan C0 stepping support

[wastedyears]

Install supported CPU and try again.

Done, but error is the same

Attach BIOS backup from phlash16
I think that modded BIOS was flashed and you can ignore this error.

Nothing changed after flashing either in BIOS or in Windows.
Ultimately I can't get phlash161700.exe to backup my bios. (/RO or /BU options caused the same error File not found)
So winphlash did it, but can't update bios with yr mod anyway.

Install your Pentium M 735A.
And make new screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0

It seems nothing changed.

It seems nothing changed.

There is a significant difference: suitable microcode is loaded for current CPU.
Microcode's version is 0x20.

How did you realize that? 
CPUID still shows cpu at 598Mhz. No speedstep.
And moreover Windows taking approx 2x times slower to boot as compared to old 1.3 Ghz cpu.
I rechecked uploaded files 1st regedt.png https://www.bios-mods.com/forum/attachme...?aid=24262
and 2nd regedit2.png https://www.bios-mods.com/forum/attachment.php?aid=24273 and see no difference.

see no difference.

Just look at Update signature.

So it's not microcode's issue.

Do Load Defaults in BIOS, save and reboot.
Make TXT-report of CPU-Z, zip it and attach to this topic.

Done. BIOS still shows incorrect CPU speed, only 1,53Ghz instead 1.7. and CPU-Z speed is 598Mhz
