Some GOOGLEing seems to show it as being 5.00
I'll swear that that's not right. MS/PC DOS 5.0 didn't come out until
1991; IBM was putting 2.88s out in 1988, the same year that PC DOS 4.0
came out. And PCDOS 4.0 came out before MSDOS 4.0--MS wisely held back
on releasing that bug-ridden beast. It could be that 2.88 was in one
of the PCDOS CSDs--heaven knows, there were enough of them.
At any rate, I'll check my copy of the printed manual and see if it says
anything about ED floppies.
Was it 4.00 that added 2.8M?
Sounds right--but
it may also be a matter of *which* 4.0. MS or IBM? I don't know which versions and/or which OEM'd
versions had 8" support.
Probably ended with 6.00
Oh, I think the device types were stubbed out long before that. After
all, there's no standard PC BIOS call that supports that. Probably
left in for the PC98 crowd (the NEC APC used 8" floppies).
