Windows® NT supported more architectures in the past, but similar to Apple with their Mac, Windows® for PowerPC required an ARC BIOS in order to be booted (please note this doesn’t only concern this architecture).
Virtualization answers like this one are OK. The aim is to still be able to test the target with this compiler.
So how to boot windows NT 4.0 on a recent PowerPC compatible (by compatible, I mean with ISA; ram modules; graphics cards…) hardware ?
And please don’t close this question because of hardware difference. Everyting is backward compatible like with the x86 version; it just can’t take advantages of new features (and in fact I’m still a Win9x user).
