Thinkpad T40 adding Dothan C0 stepping support

You can do in grub2
wrmsr 0x199 0x1128
before OS loading.

Added it to grub2.
However no miracle happened.
Windows boot time was so long.
Cpu is 598Mhz.

I executed a command
rdmsr 0x199
and saw output
Read MSR 0x199 : High 32bit(EDX) = 0x0000000000000000, Low 32bit(EAX) = 0x0000000000000612
63    56 55    48 47    40 39    32 31    24 23    16 15    8 7      0
00000000-00000000-00000000-00000000-00000000-00000000-00000110-00010010

Ps. Debian changed cpu speed after your trick.
/proc/cpuingo gives 1695Mhz

anyway many thanks man

May I ask you? What way can I patch MBR or boot sector?

I was misled you, I've decided your words about patching MBR or boot sector could solve improper CPU speed in Windows.

You need to add new code to MBR:
xor edx,edx
mov eax, 1128h
mov ecx, 199h
wrmsr

Do I understand right - this code always set cpu to a maximum speed?

Yes.
