I am forwarding the exchange between the PR originator and me.
Does i586_bcopy() have problems with certain steppings/models of
Pentium?

Try setting the configuration flag of npx0 to 0x01 in the User
Configuration menu. This will prevent some Pentium-specific
optimizaion code in the kernel code, which is causing problems in some
systems.

Thanks a lot. It boots now.
BTW, my cpu is genuine Intel's Pentium 75 MHz, why does it
not understand some Pentium-specific code ?
