I will test soon. Just now I install XP SP3 via your new english version.

Full install lasts 4 hours. All works at once.

Now I have XP SP3 on the AMD 486 and 133 MHZ,

with sound and network

EDIT: With the AMD cpu overclocked to 160MHZ, the boottime of this XP SP3 to full desktop is 90sec.

The original Bios for the Shuttle Hot 433 vers. 1..3 is from AMI.

My modded 2001 Bios is from Award.

The Bios is hard coded, so just change the name will never work.

I can ask at git, for to integrate my Bios also

I realise I'm very late and you've already solved it, but someone on vogons found this nugget of info:

https://www.geoffchappell.com/studies/windows/km/cpu/cx8.htm

Specifically :

"In the early days of Windows NT, however, not all the extant processors implemented the cmpxchg8b instruction. In versions before 5.1, every function that uses the instruction has an alternate coding for processors that do not support the instruction. Very early during its initialisation, the kernel checks whether the boot processor supports the cmpxchg8b instruction. If the support is missing, the kernel patches jmp instructions at the start of each of those functions to redirect execution to their alternates. Conversely, if the boot processor does support the instruction, and the functions are left unpatched, then the kernel requires that all processors support the instruction, under pain of the bug check"
