Subject: Cacheing IDE controllers
Date: 1 Apr 1993 12:58:12


I have a Promise DriveCache cacheing disk controller with
4 megs of ram on it. It does make a difference in the
speed of my system. Right now when doing a shutdown
I sync a couple times and then wait about 15 seconds for
the controller to flush the cache. Haven't had a problem
yet.

1. Am I just lucky? Should I worry about it?

2. Anyone patch sync or write some sort of flush utility
    to force the card to write all data to disk? The
    controller comes with a msdos utility that does this.
    I suspect that this would be very controller dependent,
    but not that hard to do.

3. Anyone got an address for Promise Technology. I generally
    don't buy anything from a place that doesn't put its
    address or phone in the docs, but the card wasn't that
    expensive and I got it from some place where nobody
    speaks English.

4. I didn't post this elsewhere as I suspect that I may be
    in for a bit of linux kernal patching.
