mup.sys

I don't know if my problem is software or hardware related, so I will also post in the hardware section. (sorry for double post).

Before I begins, here is my system specs: AMD AthlonXP 2100+ on a MSI KT3 Ultra ARU (onboard RAID controller), 512MB DDR333, MSI Geforce 4 4200 128MB, Pioneer DVR-104 and LG 24x/10x/40x, D-Link DFE538TX, Maxtor ATA133 40GB, using onboard audio.

Now, I flashed my bios and installed a moded bios that would let me use IDE3 and IDE4 as standard ATA133 IDE ports. I know for sure the moded bios works. I did this because it's the only way I found to enable UDMA2 on my DVD-RW and UDMA6 on my HD. I installed the correct drivers for the Promise IDE controller (found on the same page as the moded bios). I turned off the PC, move my HD from IDE1 to IDE3, set the correct boot setting in the bios and rebooted. I can see the WinXP splash screen but after that it hangs in complete darkness (keyboard not responding) ... I rebooted in safe mode to find out mup.sys was the problem. I them switched back to IDE1 and everything works just fine.

mup.sys is network related, so I tried to uninstall my nic, same problem. On experts-exchange.com, 2 threads speaks about boot problems due to mup.sys and the 2 users has a maxtor HD, so is it hardware related? I am so confused, I want it to work so much. Why does WinXP boot without a hitch on my IDE1 and can't load a network related file on IDE3?

Any inputs would be appreciated.

Sounds like XP can't see your IDE3. I think the reason it's realated to mup.sys is that it likes to do that nice little hardware scan over to M$ to make sure it's on the right system. DId you try going into manual repair, and expanding the 'mup.sys' file off the CD replacing the old? Also, did you install the RAID drivers into Win? (I'm sure you did. Just had to check.) Did you also try to diable RAID, but not the controllers, and see if it would work that way?
