Here's a question which has been on my mind a little ...
In OS/2 2.0 there is support for multiple virtual DOS machines. How
far does this virtualization go? Would I be able to, for example,
load some other 8086 operating system, like CP/M (not that I want to)
or MINIX (Yeah, I want to =]) in a VDM?
I guess the important things would be that the IVT gets handled correctly
(eg 8086 interrupts are handled in their normal fasion) and that
I/O port emulation, or mapping be provided.
Anyone know these answers? IBM? Microsoft?
Thanks, in advance,
Steve

IBM? Microsoft? (Sigh) Microsoft's NT is supposed to do this, but I seriously doubt that 2.0 will let you boot any other OS simultaneously. I guess you'll have to wait until NT is released.

Actually I read in InfoWorld that Dr. Dos 5.0 is being booted in a VM. I think I also read that other real mode operating systems should work. The source is not that good, but... -Gary
