Installing an ISA Card
Both PnP (Plug abd Play) 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.
5.
Turn off the system.
6.
Locate the expansion slots and install the PnP ISA and PCI
cards.
7.
Turn on the system. This time BIOS automatically configures the
PnP ISA and PCI cards with the available resources.
