C. As another example, if you install a SCSI card into slot 1, which uses PIRQA,
do not install an E-net card into slot 2, 7, 9, or 10, because these slots also use
PIRQA.
To map hardware IRQs, during the BIOS POST, press [F2] to enter the BIOS Setup.
Select the
Advanced
menu at the top of the screen. Select the
PCI
Configuration
submenu. PCI IRQ lines can be mapped to any one of the IRQs
that are displayed in the Setup menu.
PIRQA => PCI IRQ line 1
PIRQB => PCI IRQ line 2
PIRQC => PCI IRQ line 3
PIRQD (USB IRQ) => PCI IRQ line 4
