>Confused? Wait until someone tries to explain how this fits with OS/2.
Actually, that's pretty easy. OS/2 uses protected mode, and extended memory.
OS/2 doesn't (cannot?) use expanded memory at all. Sorry, folks.
On a different subject, is anyone else hoping that OS/2 flops as strongly
as I am? I don't have any particular prejudice against Microsoft: what
I mean, is that I would hope that ANY operating system based on the
80286 processor would fail, since the architecture is exceedingly
brain-damaged (I thought the 8088 was bad until I looked at the 80286!)
I still don't see why IBM/Microsoft couldn't have based OS/2 on the
80386 instead. Intel announced their P9 (80386 in a 80286 compatible
package) pretty early in the game: IBM could have supported their
AT base by insisting that customers upgrade their processor before
upgrading their operating system.
Certainly, I believe that bringing out the PS/2 models 50 and 60 with
80286 processors was a serious mistake, wasn't it? Couldn't they have
put slower memory and slow 80386 processors into them, and still been
able to differentiate the high-end model 80?
