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? >>If you're not sure but optimistic, I'd be happy to give it a shot and >>report back.

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 ;-). >>Jon >> >>P.S. Just be thankful you're not running Windows 9x.

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. > P.S. My other email address (for the next week) is scott_long@adaptec.com Nice... Jon
