- If the MFM disk is not in CMOS, it will not be supported. If the ST51
- is an AT controller, you can use the controller, just disable the BIOS on it.
- If it's an XT controller, you are SOL.
-
- You can pick up MFM/RLL controllers for < $20 if you talk to the local
- technicians - they pull them from equipment when upgrading systems
- to IDE drives, and practically give them away.
-
- Note that if you change controllers on an MFM drive, it may not be reliable
- unless you re-lowlevel format it.
-
- As far as the SCSI disk : newer SCSI drivers (kernel binary / sources
- available from headrest.woz.colorado.edu as /pub/linux/scsi* and vmunix* -
- pickout the newest files) handle things more gracefully. Note

- See above, and after you have it working, you can use a program like winiboot
- to selectively boot DOS or Linux.
