ISA expansion slots
There may be several dual-connector 16-bit ISA expansion slots on the
motherboard. The 16-bit ISA slot is a combination of a 62-pin edge connector and
a 36-pin edge connector.
The dual-connector ISA slots are intended for dual-connector adapter cards that
were designed for IBM AT-compatibles. You can also install ISA adapters that have
a single 62-pin connector (8-bit cards) in the dual-connector ISA slot.
You can use any available ISA slot for an ISA adapter card. Make note of the slot in
which you place each card, for external identification.
Installing adapter cards
Before installing any adapter cards, read the appropriate
section in this manual and in the manufacturers’
documentation.
1. If you are installing a combination of PCI slot adapter cards and ISA slot
adapter cards in a Senstar 100 CU, install the PCI adapters first, and then
power up the computer.
2. Review the PCI device listing that is presented by the BIOS during boot-up, or
use the QNX
show_pci
command to determine the IRQs that were
automatically assigned to each PCI adapter by the system BIOS.
3. Make a note of the PCI adapters’ IRQs that are used.
4. Follow the manufacturers’ directions to set the IRQs on the ISA slot adapters
to unused IRQs. You may need to designate in the computer’s BIOS that the
ISA card IRQs are used by ISA.
5. Install the ISA adapters, then power up the system and verify the IRQ settings
(no conflicts).
