Boot fails at mup.ssys after XP SP2 install

J

I am implementing several brand new Celeron D workstations
with XP Pro. Everything works fine sith SP1. When I
install SP2, whether from CD or by Windows Update, the
systems hang during power on boot and only way to shut
down is power button. Safe mode hangs at mup.sys in all
cases. Windows repair does not work and only solution is a
clean install of SP1.

Any suggestions?

Can you try disabling L1 & L2 cache from the BIOS? This will make the system
run very slow, only do that if you are already on SP2.

Be aware of the following, you may want to run this utility to see what
level you are at. If you are impacted by this please post your system brand
and specs. Where did you get your system from?

If your machine is using Intel Prescott processors, the BIOS on the machine
may have not supplied an appropriate (production - level) microcode update
for your processor(s). You will need to get an updated BIOS for your
machine that supplies at least the minimum production level microcode update
as shown in the table below (contact your machine vendor if necessary). The
machine should not have been shipped with less that these minimum
(production level) microcode updates provided in the machine's BIOS.



Family 15 (0xF), model 3, stepping 4: Must have a microcode update signature
of at least 8. Latest microcode update signature is E.



Family 15 (0xF), model 3, stepping 3: Must have a microcode update signature
of at least 7. Latest microcode update signature is B.



Family 15 (0xF), model 3, stepping 2: Must have a microcode update signature
of at least 7. Latest microcode update signature is A.



Check your processor details using the utility from Intel:



http://support.intel.com/support/processors/tools/frequencyid/



The field reported as "Revision" is the microcode update signature.



After you install correct BIOS on your machine, the machine will then boot
up and your install should proceed.



The best advice is to run the frequencyid utility from Intel before
installing XP SP2. If your processor does not have a revision of at least
the minimum shown in the table above, get a new BIOS for your machine and
then run the frequency utility again.



An installation of Windows XP SP2 should not be attempted if you are
affected by this and do not have the correct BIOS installed.
