I have a CQD-220/M and it does boot. I don't recall a problem, but I 
know there was a problem with the KFQSA when using the DU boot loader.

Can a CD-ROM drive be attached to the CQD-220/M? If so, what drive types 
have been successful?

Is there a way to convert a CQD-220/T to a /M or /TM? What about a 
Viking TMSCP SCSI controller (forget the model)? I got them cheap, 
knowing that they didn't do disk and hoping there might be a conversion 
method some day.
