It's quite a common problem. Apparently more common on Compaqs because of 
all the proprietary junk they load at startup.

The problem is not with Mup.sys, but with whatever it's trying to load 
immediately following that.  Usually it's a driver problem, as drivers load 
immediately after mup.sys.

If you're using Compaq restore and boot disks, you're only repeating the 
same problem.

There are many reasons why Windows fails to load at this point--- there are 
100's of varied and different answers, with very few common threads and not 
much logic to it.  Try googling mup.sys for some possible leads. Very 
basically, it's usually a driver conflict.  Sometimes, removing all 
peripheral hardware helps, in case there's a printer, scanner, or whatever 
incompatible to Compaq. The problem is not unique to Compaq, but seems to 
be more common to brand names generally, with all their proprietary stuff 
which CAN be incompatible with certain hardware/software combinations.

In some cases it's an intractable problem and you'll need to reformat and 
load a clean (not proprietary) copy of XP.
