I posted a message which is slightly in error.  The drive types for an
RLL drive do not exist on a IBM AT.  Thus, disk manager is required to
access the full potential of the drive.  Alternative solutions is to
use a user defined drive which some ROMs support.  Below is the email
message I recieved.

NO - he wants to put it in an AT, which has CMOS setup, which leads to problems
with which drive types his ROM knows, which are probably all MFM drives, so
if he just hooks it up and auto-configures, he loses 50% or more of his
drive capacity right there!

Solutions: Disk Manager, new ROM, drive type 47.
