Anyone know how to ELIMINATE Mup.sys. It is wrecking my XP!

[Larry Woods]

First, Mup.sys hangs the boot for a minute or so. Also, I "think" that it
might be behind delays that appear all over the place when I am operating
XP. According the the doc that I can find on Mup.sys, there isn't any
reason that it should be doing anything anyway.

TIA,

I disabled Mup.sys (by the way, Mup.sys was NOT defined using the Diagnosic
Console; only Mup), but now I have possibly a BIGGER problem. At boot time
I am now hanging on NDIS, and for about 5 minutes. Then the boot continues.
This is VERY confusing since I have a second computer that also has XP Pro
installed on it, connected to the same LAN, and it comes right up!

?????????????

TIA,

Mup.sys is a red herring - it just happens to be the last file that
normally gets loaded (as you see if you boot in SAfe Mode on a healthy
system) so all one can say is that something is going wrong in the
initialisation of the system once all files are loaded.

Best guess must be trouble with a driver. Boot to Safe mode after
hitting F8 as the BIOS info (or makers logo) goes to a black screen, to
get the Menu. If that is OK then a driver is almost certainly it. In
that case Start - Run - MSConfig.exe and on the Boot.ini page check
/BASEVIDEO and shutdown to restart. If that comes up in regular mode,
but with restricted video, then the trouble is in drivers for the video
card - check out the maker's site for new ones

This is common with XP if you have SP1. It causes conflicts
with some AGP drivers and USB2.0 . The way to fix it is to
insert your XP cd and repair from the install. That is the
easiest awy anyway. I hope this helps. Let me know if it does.

Bear in mind that a repair reinstall takes you right back to the
original state of the system, with all updates removed, including SP1 if
that is not included in the CD itself
