Mup.sys error after hardware upgrade

I have a linux/windows dual-boot setup which was working fine. After upgrading to a new CPU and motherboard (and more RAM), linux is still booting fine (and the windows drive can be mounted without issues), but Windows XP hangs after loading Mup.sys, with the typical useful blue-screen error message (error detected, shutting down). I also tried booting from the original Windows XP install disk, which crashed with the same error.

My new hardware components are:
* Sabretooth 990FX R2.0 motherboard
* AMD FX 8350 CPU
* 8GB DDR3 RAM (Kingston HyperX, in two 4GB modules)
Also running a 3D graphics card, but that was already present in my old system and working fine.

Any ideas how to approach this?

Found it - the new BIOS had the SATA drives running in AHCI mode, changing it to IDE made WinXP happy again. Just a bit strange that it even caused boot from CD to fail.
