Oh dear. What sort of PC are you on, and what's the rotational
speed of your hard drive?
I had some patches (from David Brownlee?) that increased speed by
about 40% on my 486 with 5400 RPM drives (1.4 MB/sec to 2 MB/sec),
let my 486 run with HP drives (the old one couldn't even get to
single-user mode), and made no difference at all on my Alpha UDB.
Fvdl send me his patches, which I was supposed to have a look at
and test. Unfortunately, I've been so busy this week that they're
still sitting in my mailbox, and so he just went ahead and commmited
Try the following patches against the driver from before the upgrade,
and let us know if that makes any difference.
I will sit down and have compare fvdl's patches and the other ones
and see if there are any significant differences, and test them on
my Alpha. I don't know if I'll be able to test them on my 486 with
the Genuine Exploding HP Drive before Monday, though.
