MISCELLANEOUS TECHNICAL NOTE

Note:To select a particular IRQ setting for a particular PCI slot, short the two pins located at the intersection of the row that corresponds to that IRQ setting and the column that corresponds to that slot. The IRQ address settings selected for the four PCI interface slots by these jumpers must be identical to the address settings defined for the PCI slots on page 2 of the BIOS setup utility.
