Write your reply.

assistant: In a message dated 02-19-98, Jack Stein said to Howard Brazee:
I cannot put OS/2 further out than I can put OS/2.  IDE archecture limits how
far out the boot track can be.  Since NT puts the boot track on C:, the rest
of the boot drive can be beyond this limit.
If I don't use IDE, OS/2 can boot anywhere.
It still uses the bios to read the IDE track.
I have never heard of putting the boot manager anywhere except on hard drive
0. Please tell me more.
It is a bios limit.  This is the limit which I have been talking about all
along.
I said that, and then still went EIDE with my upgrade.  Too much money.
