oh dear ... dude ... check the Holly Manuals again...
on a 386, in real mode, you *can* use 32 bits registers. and 32bits addressing modes (things like [eax+ecx*8]). You'll just be resetting the CPU if you attempt to do something like
when eax is above 0xffff ...
Of course, you should better check you're running on a 386+ before issueing such code, but you of course did, didn't you ?
