Various people have reported that 1.5.5 won't boot on a 6 MHZ IBM AT. Apparently IBM is not IBM compatible. It used to work. Does anyone have any more experience, ideas etc? Andy Tanenbaum (ast@cs.vu.nl)

I was one of those people. The problem is somewhere in the protected
mode code, I'd bet. 1.5.5 will boot an original IBM AT with the
bios_wini.c driver running in real mode. If I get the chance, I'll
make up a version with at_wini.c to run in real mode and see what
happens.
