Figure 3-6: PCI configuration screen
3.7.1 IRQ-xx assigned to : PCI/ISA PnP
These fields indicate whether or not the displayed IRQ for each field
is being used by a legacy (non-PnP) card. Two options are available:
PCI/ISA PnP or Legacy ISA. The first option, the default setting,
indicates that the displayed IRQ is not used to determine if an ISA
card is using that IRQ. If you install a legacy ISA card that requires a
unique IRQ, you must set the field for that IRQ to “Legacy ISA”. Say
for example that you install a legacy ISA card that requires IRQ10.
You must then set “IRQ-10 assigned to :” as “Legacy ISA”.
