OK, I thought it sounded too good to be true.

You seem to be in the know, perhaps you can answer this question 
(without violating an NDA):
Are the older cards capable of running the new firmware but Adaptec has 
just not updated them (nearing EOL, etc.), or is there more to it than 
just having an i960?

Are they fundamentally different, or would you think this possible with 
a decent amount of work?  If you don't have any idea, fair enough -- I'm 
just trying to figure out how much effort this will take and if it's 
worthwhile for me to try.

Disks (backups) and children (whoa there -- I'm only 24) I don't mind, 
but I draw the line at dogs.  That's just plain hateful ;-).

I did not report it to Adaptec tech support -- at the time I experienced 
the corruption, I thought it was just Win98 being its inferior self. 
Only months later (when I had a renewed hankering for the awesome game 
Tie Fighter) did I consider the 2100S might be causing it and try IDE 
instead.  IDE worked fine, so I assumed the 2100S was to blame. 
Considering all things were not equal (same basic machine but I think I 
had a new video card), it may not have been the 2100S.  In any case, I 
no longer want/need to put Win98 on the 2100S, so it's not an issue for me.

Nice...
