Wayne,

I don't think you did anything to "cause" the mismatches. I recall the same problem,
when I setup and used IDE drives. You have to carefully read the data at the website,
because, as I recall, they sometimes talk about 2 different set of numbers (cylinders,
sectors, etc) for a given drive.

I agree with Steven. Set your system up for auto detect at the BIOS. It will probably give
you a set of numbers for the drive and select LBA for the access mode. That's what I
did. As long as the total result (in the BIOS) is 40 GB, you should be OK. Once you use
an access mode and partition and format it that way, you have to stick with that mode.
You cannot change it sometime later and copy your data/files back onto the drive

There's been some issue about where or not to use the OS/2 utility diskettes (4
diskettes), or a modified set of OS/2 diskettes, or the 2 diskette set from BOOTOS2. In
the end, it really does not matter. Use what ever method feels more comfortable to you!
The bottomline here, though, is that you've got to get a good set of diskettes, ones that
will work on your barebones, in order to partition and format the 40 GB IDE drive.
Different people have different perjudices toward or against each method. Again, use
the method you like the best, but get a good set of IDE drivers on it. Test it out first on
your P2 to make sure that it works (you don't have to partition or format anything on the
P2; you just want to confirm that it boots to an OS/2 commandline on your P2).

Previously, you mentioned that the barebones bootup stops on the diskettes with
diskette 2 and the os2cdrom as the last diskette:

Wayne said in a previous message:

OK! My advice: Try temporarily disconnecting the secondary IDE inside the
barebones. Disconnect it at the IDE connector on the motherboard. Go back into your
BIOS and redo auto detect. Save the BIOS settings. Then, try to boot to an OS/2
commandline, using the diskettes. You won't have the use of the DVD, but you may
isolate the problem to that unit. Another thing is, please make sure that you can
successfully boot the diskettes on your P2 (what I stated above) as the first step, before
anything.

Hope this helps!
