4.3.2 Installing ISA Cards
Both PnP and non-PnP ISA cards require specific IRQs. When installing ISA cards,
make sure that the IRQs required by these cards are not previously assigned to PCI
devices to avoid resource conflicts.
Follow these steps when installing ISA cards:
1. Remove all PnP cards installed in the system, if any.
2. Install non-PnP ISA cards.
3. Turn on the system.
4. Use Windows 95 or ICU to manually assign the appropriate IRQs to the cards.
This ensures that BIOS will not use the resources assigned to the non-PnP ISA
cards.
BIOS detects and configures only PnP cards.
6. Turn off the system.
7. Locate the expansion slots and install the PnP ISA and PCI cards.
8. Turn on the system. This time PnP BIOS automatically configures the PnP ISA
and PCI cards with the available resources.
