[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.
