Why d
It might be convenient to have a completely unoptimized 386 kernel. While
this would obviously be non-optimal in all cases, it would be compatible
with everything and probably faster on non-386 than a 386-optimized
kernel. Of course, the gains are probably not worth the time it would take

Jeff,
Can we also combine mutiple segments from different processors or is it
a one-sy two-sy king of affair? If so, we're there, it just becomes a

Code is. Data isn't. Gcc packs data into the segment like sardines in
a can (NT code does to). 16 byte align this as well. NetWare 16 byte
aligns everythin with an align 16 directive in the data segments of
assembler modules.
