Installing ISA Cards
Both PnP and non-PnP ISA cards require specific IRQs (Interrupt
ReQuests). 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.
Turn off the system.
2.
Open the system and remove all PnP cards installed in the
system, if any.
3.
Install non-PnP ISA cards.
4.
Turn on the system.
5.
Use Windows 95 or ICU (ISA Configuration Utility) 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.
