No, I have several Dual BX boards, but I'm running the latest service
packs. You did a clean install, not an upgrade, right?

Confirmed - a clean install.

No you should not be seeing this. The BX-440 is common chipset so
shouldn't be a problem. When you say the processor is being used by
kernel what do you mean? There is not a thread called kernel. If you
want to get details of everything one way is to use pslist from
sysinternals.

Actually what I meant was the high CPU shown in task manager was reflected as
kernel time (as opposed to task CPU).

Anyways, there is a happy ending. After many lengthy searches that finally
devolved into discussions on switching MP kernel types for machines which
implement power managament by APIC versus the older APM, I went to confirm
that my machine was indeed APIC compliant and the last BIOS I flashed (in
1999) did list as one of its updates, APIC compliance.

I bit the bullet and installed the last ever BIOS from the vendor published in
2000 and listed forever as "beta". It officially was to support drives over
73 Gb, but the collateral effect of installing that beta BIOS was no ill
effect on any other subsystem and *surprise* something else fixed to the
extent that I no longer see total system CPU at 50% (in effect burning up 1
CPU's power doing nothing).

After WINLOGIN does its business at startup, everything settles down and I
have two engines ready to work hard at user initiated task code.

Interesting that none of this flared up during the time the box was running
NT. Had I not solved this I may very well have stayed with NT4 at SP6a.
Currently I have no application requirements pushing me into W2K. I just used
this period of protracted system stability to try and ease into something a
little more current.
