Altiris DS 7.5 WinPE x86 boot always BSOD with percsas2.sys

When I try to boot a machine on WinPE 4.0 x86 I always get a crash on the percsas2.sys file.  Which is odd since if it's for a PERC card, none of my clients have those.  I think there's a corruption with that file or something similar.  I have deleted my preboot configurations and made new ones, and the propblem persists.

Thanks!

*WinPE 4.0 x64 is working correctly, though I'm having trouble finding 64bit NIC drivers for older hardware, thus the 32bit attempts.  I have another forum post about how to remove a bad driver from the PreBoot database.
