Clint! Do you have a third party utility such as "Cacheman"? The version
5 is quite extensively built. Also You confused me quite a bit as by your
description of your IDE setup as actually SCSI. As you may remember I have
had a SCSI system for years and it truly is night and day between SCSI and
their additional formats and EIDE or IDE or ATAPI etc. There is a
different electrical setup and pin connection.
You are quite ahead of me as I have not installed Win2K on my system as of
yet but as I had told you privately I learned a great deal about the system
as an OS but not unfortunately in connection with the technical query that
you have placed.
There are additional groups you can join Clint that will give you a good
deal more access to a "higher" experienced readership than this one. As I
understand it, XP will be highly configurable and will dumb down drive
settings so the user will have less confusion as to tweaking performance.
Ben Moore has had Win2K for quite a while as does a few of the others. I
will send you Ben's email.
Hope some of this helped you,
Barry
