   Huh. The only reason Windows XP didn't run on a 486 was the use of a single Pentium instruction.

     @sun @condret It still needs CPUID somewhere deeper in the system, so it only works with late 486es that implement it.

     @sun @condret Probably. People in that thread report success on Am486DX4, but not on Intel DX4.

     @sun @condret XP could also apparently boot on SuperEGA cards, and it looks quite aesthetic there. Unless either 86box or the emulated card itself somehow manages to partially emulate VGA modes.

     @mint @condret maybe it was just an overlap of vesa modes and xp couldn't tell the difference

     @sun @condret Maybe. When I set resultion to more conventional 640x350, it froze shortly after ntldr. Apparently some (physical) SuperEGA cards do offer VGA emulation.
