Chapter 2 Installing drivers and host cards
Suggested hardware settings for AT-FAST
If you are installing AT-FAST hardware you should examine your system configuration and
determine non-conflicting I/O addresses and IRQs for use with each ISA card. Some
suggested locations to try:
As can be seen from the above, I/O space is in short supply especially if installing multiple
cards - particularly 16 port units. Using PCI-FAST cards in multiple card configurations is
advised. If suitable non-conflicting addresses can be determined then up to four AT-FAST
cards can be installed.
The command hwconfig can be used to display resources used by existing hardware.
The parameters base and offset give the start address and size of the I/O space used by a
card and vec gives the IRQ number. This list is not exhaustive as some drivers do not
declare all the resources they use.
On SMP (multi-processor) systems an additional command displayintr can be used to show
the IRQ lines currently in use by the various device drivers.
Card I/O base IRQ Suitable for
1st 0x180 5 4 and 8 port cards.
Possibly 16 port if using
SCSI hard disk
2nd 0x100 10 All cards
3rd 0x240 11 4 and 8 port cards
4th 0x280 12 4 and 8 port cards.
Possibly 16 port if not
using COM2
Note
Do not use IRQ12 if a
PS/2 mouse is
connected.
