TODO:
- bp 932d1, ROM banking that reads at 0xffffe???
*/
/*
- Doesn't detect proper CPU type;
- "Memory test fail" at POST, needs um8498f "memory controller" emulation
(non-PCI with shadow RAM?), also cfr. correlated at.cpp romsets;
- Sometimes POST will trip an invalid groupFF_16 modrm FF at 000F00B2, causing an hang;
- bp 932d1, ROM banking that reads at 0xffffe? Is um8498f ROM boot capable?
