That's right--INQUIRY is SCSI; IDENTIFY is ATA.  

A lot of the bridge boards were from very early in SCSI history, 
where the "standard" hadn't yet set.  I've got to go back to my SMS 
OMTI bridge board manuals, but I think the drive geometry could be 
obtained there by simply reading the bridge board buffer right after 
initialization.  I'm also trying to remember if the bridge board kept 
the information on a reserved sector on the drive.

It's been too long...
