Hi, Barbara -- 

I'm not claiming any direct 
experience of your problem, 
but, as I recall, another 
device driver, ASPIDISK.SYS, 
is required under the 
Adaptec scheme.  It's 
normally invoked after the 
ASPI driver (in your case, 
that's ASPI8U2.SYS) and 
before the CD-ROM driver.  
Whether ASPIDISK.SYS can 
find a "logical FAT 
partition" -- I'm even sure 
what that term means -- is 
another issue.
