Next time it happens, I'll boot from a floppy and see if I can get fdisk 
running that way.

Lonni, while it is not acting up now, when I try to use the SCSI 
configuration utility that can be entered on boot-up, it seems to not 
be functioning properly,  I cannot access all of the features that are 
supposed to be available and menus seem to be incomplete.  It looks 
like some kind of ROM problem associated with the controller.  I will 
see if there is some obvious ROM that goes with the controller and see 
if I can get another??

On SCSI controller boot-up (after bios boot), I see SCSI ID numbers (the 
jumper selections on the SCSI connector) but nowhere do I see a 
graphical display of SCSI IDs such as sda, sdb, etc.  Isn't that part 
of the kernel??
