Why is the temp fix to rename update.sys? When can we expect a hotfix from
MS for SP2's update.sys? A buggy SP2 update.sys with respect to the
Prescott seems to be what's really behind this whole issue, right?

You're not alone! You just described the exact same
problem I experienced overnight. I'll let you know if I
find something out.

computer needed to be restarted to complete the
installation.
When I restart the computer it freezes shortly after
start up with Windows XP on screen.
If I start the computer in safe mode with networking
either on or off, The computer freezes with

Known issue with Intel Precott processor and SP2, if BIOS doesn't push
Intel's bugfixes to the processor.

To uninstall SP2, do this:
- CMOS setup, disable L1 and L2 cache
- run XP; it will run, but very slowly... have faith!
- Add/Remove Programs, uninstall SP2
- CMOS setup, enable L1 and L2 cache

To live with SP2 (kludge), do this:
- use your maintenance OS to rename away Update.sys
- now XP SP2 will run "fine" (that's how I'm running my test PC)
- if you have SP1(a) Update.sys, can put that back if you like

To really fix the underlying issue:
- get a BIOS update that pushes microcode rev 8 to Prescott
- steppings 2, 3 = C0 are OK on rev 7
- but stepping 4 = D0 requires rev 8

If you find your mobo vendors's very latest BIOS doesn't fix the
issue, don't be surprised. Even Intel seems just-in-time on this; I
read up Intel's own 865G Bayfield mobo, and...


http://www.intel.com/design/motherbd/bf/bf_proc.htm

Outlines processor requirements, which are...

Mobo -405*, BIOS P18 Prescott Celeron D
Mobo -405*, BIOS P13 Prescott Pentium 4
Mobo -405*, BIOS P11 Pentium 4 Extreme Edition
Mobo -any, BIOS P11 Pentium 4 at 3.4GHz
Mobo -any, BIOS P06 Pentium 4 at 800MHz base
Mobo -any, BIOS P03 Pentium 4
Mobo -any, BIOS P03 Celeron

* C28144-406 req'd; all other C2???? are -405 OK
(Every Bayfield I've seen here has been C25843)

Page 9 links motherboard -40x rev to BIOS version; excerpt:

C25843-408 = BIOS P16
C25843-407 = BIOS P13
C25843-406 = BIOS P10
C25843-405 = BIOS P09
C25843-404 = BIOS P07
C25843-403 = BIOS P07
C25843-402 = BIOS P06
C25843-401 = BIOS P03

This contrasts with Intel's assertions that -405 is OK for
Prescott, and that only tardy 3rd-party motherboard/BIOS
vendors have failed to be Prescott-ready.

When you look at the BIOS versions, the threshold for
Prescott Pentium 4 is -407, not -405 as claimed, and not
one C25843 is fit for Prescott Celeron D.

BIOS revision history, as summarized below.

P19-0065 03/08/2004
P18-0063 22/06/2004
- latest processor update
- Celeron Badge for Prescott
P17-0061 22/04/2004
P16-0060 12/04/2004
P15-0058 05/04/2004
- latest processor update
P14-0056 10/02/2004
P13-0053 22/01/2004
- enhanced for future processor supprt
- code to diff some P4 from some Celeron
- latest processor update
P12-0051 16/12/2003
- supports P4 Extreme Edition
P11-0048 14/10/2003
P10-0046 24/09/2003
- latest processor update
P09-0043 25/08/2003
- latest processor update
P08-0038 24/06/2003
P07-0036 19/05/2003
P06-0033 23/04/2003
- latest processor update
P05-0030 16/04/2003
P04-0028 14/04/2003
P03-0024 04/04/2003
- initial BIOS release

So the "Prescott Celeron OK" BIOS revision came out in June 2004 -
same month as Prescott Celeron itself - and that version has yet to
ship with the -403 to -408 stock we buy new right now.

What does that tell you about chances of not falling into this hole?
