Just put a new mother board and intel duo combo in place and a safe boot
fails at Mup.sys. If I try to reinstall from an XP upgrade disc I get an
alert that I can't find processor instruction CPUID & CMPXCHG8B. Bios shows
the processor so I'm confused at that on. Thoughts?

Click to expand...

For whatever reason, the installer cannot find some necessary CPU
instructions.


First off...is your XP cd sp2?
If not , you may have to create a new XP install cd with sp2 slipstreamed.



If you are using XPsp2 and it's not working then something within the
installation itself is corrupted.

though it could be due to a dirty or scratched CD...

it's possibly due to a RAM error or timing issue.

Try underclocking the RAM or running a RAM diagnostic test
 
Still no luck. Replaced the ram and now may have to re-install the old boad
and attempt to construct a slipstreamed xp2 cd but I still don't think that
will help to find the ID. ANyone with thoughts.
