If I were you I would definitely try getting a cheap IDE drive and using it for data (reiserfs of course). You might even try two IDE drives and drop the SCSI controller. Also, it sounds like you're using a USB mouse. I use the little converter from USB to PS/2 just to avoid USB interrupts. My setup now has ICE1712 [Envy24] on IRQ 10, nVidia NV6 [Vanta] on IRQ 11 shared with D-Link Ethernet, dual USB controllers on IRQ 5. Jan
