Anyone using XP emulation SP2 form xpefiles ?

I tried to use the XP emulation SP2 configuration downloaded from xpefiles
on an ACPI multiprocessor computer but the FBA suddenlly stops rebooting the
pc and no error are then reported in the installation log.

I undestand this is a too generic situation to be asked here and I do not
expect anyone can directly solve my problem but I'm asking if someone is
using this configuration and if yes what kind of problems where found to let
the fba complete succesfully.

Thanks in advance
Frank
