What is the correct way to set a PCI Interuppt in the BIOS and the
Motherboard jumpers for a GIGA NCR SCSI Card ?
The Card has a primary/secondary jumper for selecting IRQ. The manual
says that the jumper in the primary position is IRQ 9 and in the secondary
position can by any other IRQ ?
How does all this work ?
Am I really losing that much HD I/O performance with my current settings ?
