I'd been checking up on Russel Williams - we've not been able to find one who is an employee of Microsoft, nor have I been able to find one who was. The fact is, that to better support 32-bit Windows, a DOS device driver model is being introduced which is both re-entrant and 32-bit protect mode. (For those who'd ask me, a 32-bit Windows development kit is to be released later this year, product, next year). 32-bit Windows apps will be able to follow a 32-bit code path from execution to hardware with no mode switching. So, yes, dos was a real-mode, non-rentrant interrupt handler and file system, but no one in our industry would make 'always' predictions about the future - its all software, anything could happen. Russel Williams, whoever he is, will be wrong. Alistair Banks. Systems Division, Microsoft.

Simply amazing! The guys at Microsoft have managed in only 11 years of DOS development to implement OS tech. that is only 20+ years old. These guys are practically saints! We'll actually see software that can utilitize hardware that's only been out since 1986 from them. Will wonders never cease! All that work for "power users" running Windows, what a joke! ;-) David Boles -- ------------------------------------------------------------------------------- David Boles Applied Research Laboratories dboles@ccwf.cc.utexas.edu apas611@chpc.utexas.edu This space for rent, apply within. -------------------------------------------------------------------------------
