I had dtools installed and running without any problems. Then i upgraded and my system hung durnig the first boot when it tried to access the virtual drives. I uninstalled dtools and the system booted without problems. The i tried re-installing dtools but it gave me the error above. I changed the mobo,cpu and ram.
Asus P4S8x, P4 2.4ghz.
SiS5513 Dual channel IDE Controller (onboard).
PCI promise IDE controller (ultra66). But that was in before i upgraded and gave me no problems.
Windows Millennium (yes i know everyone hates it but its always worked miracles for me somehow..)

thanks for your time.
