But thats the thing - the FORMAT /S command works just fine. It formats the C: drive, copies over command.com, io.sys, and msdos.sys. I then reboot from the "new" C: drive. Thats when I get that error. I put the A: disk back in and just rename the io.sys and msdos.sys files to the "ibm" name style, and it works.

That's what doesn't make sense. Its obviously the same command.com. How can it require one naming convention on one disk, and the other on the other? Weird.
