[Solved] Microcode support for Tyan Tempest i5000VS (S5372)

[MuF123]

Post a result of /proc/cpuinfo
"not microcode problem" because the native BIOS has microcode for E5450 to A07 version.
P.S. I can't see CPU photo.

just keep in mind that this is other cpu (compatible)

with E5450 I can't get past POST, so I can't make any screenshots - cpu photo fix: http://imgur.com/a/zvWaR

I'll try to find a code with this CPU check.

I've found interesting code in BIOSCOD01.ROM module:

Code:

200B     mov   ebx, 0FFBC0100h
2011     mov   al, es:[ebx]
2015     test  al, 4
2017     jnz   2030h
2019     mov   si, 0B04h
201C     call  far ptr 6011h:52B6h  ; printing "This Proccessor is not supported"
2021     call  far ptr 6011h:50E4h
2026     mov   si, 0B08h            
2029     call  far ptr 6011h:52B6h  ; printing "Plesse Check Processor."
202E     jmp   short 202Eh          ; halt
2030     <normal booting>

One byte patch is needed:

Code:

2017     jmp   short 2030h

Please try my new mod.
