PCCHIPS M598LMR (V9.0) - OK

[Marcos Felipe Rasia de Mello]

PCCHIPS M598LMR boards were incredibly popular in Brazil ~12 years ago.

There were, as usual from PCCHIPS, several hardware revisions. Some I
remeber are 1.3, 5.0, 6.0, and 9.0. The difference between them is not
very clear, but as a general rule the latest BIOS (2K1222S.ROM)
applies to all of them, with one exception: if it use an ASD AE29F2008
or Winbond W29C020 flash, the 2K1222S.ROM BIOS will *not* work (the
board will not complete POST). In case you have one of those chips,
you should use the 2K0930S.ROM BIOS which works fine.

Mine has an ASD AE29F2008-12 flash (detected as "Winbond
W29C020(C)/W29C022" by flashrom) and I successfully programmed the
2K0930S.ROM BIOS.

Logs attached.
