Do all of these binaries actually run properly on 386, 486, Pentium,
K6*, Cyrix, IDT, and Athlon chips, and any other x86 compatibles?
No? Then forget it.
The configuration notes for the kernel, for example, specifically say:
If you specify one of "486" or "586" or "Pentium" or "PPro", then
the kernel will not necessarily run on earlier architectures (e.g. a
Pentium optimized kernel will run on a PPro, but not necessarily on
a i486).
Hamish.. no Intel chips in use at my place, thanks.
