Each PCI Slot has three option fields:
The first field is the "Latency Timer" setting. Do not ch ange the
"80 PCI Clock" setting. The default enables maximum performance.
The "Using IRQ" field assigns a system IRQ to a PCI slot. An
"N A" (N ot Assigned) setting means no IRQ is assigned to that slot.
The default IRQ settings are:
Slot 1: 10
Slot 2: 11
Slot 3:
Slot 4:
9
NA

Software Guide
You can change the default to another setting. If you do, make
sure that you do not choose an IRQ already in use.
Note:
1. If you install a PCI Enhanced IDE controller card that is set to
use both IDE channels, you must set the IRQ to the "14&15"
option. This does not apply to the on-board PCI IDE control-
ler which, if enabled, automatically uses these two IRQs. For
an IDE card that only uses one channel, set the IRQ to "14".
2.
If you install a PCI IDE controller card that uses an IRQ
'Paddleboard', you must set the IRQ to "NA".
The third field, "Trigger/Routing", selects how IRQs are routed.
It assigns, or 'routes' the IRQ listed in the previous line to the slot
using one of two 'trigger' methods, Level trigger, or Edge trigger.
Most PCI cards use the Level trigger method. Level triggering is
handled two ways. The default, "Level/ Auto", can detect if an in-
stalled card u ses an IRQ, and if not, leaves the selected IRQ free for
other use. The alternative is "Level/Forced". In some cases, a card
you install may not b e completely compliant with the PCI
autodetection specification that allows "Level/ Auto" to automati-
cally determine if a PCI expansion card uses an IRQ. If you install a
card and it does not seem to be working properly, try changing this
setting to 'Level/Forced'. This will assign the IRQ indicated in the
previous line to the slot, and therefore the card, even if the card's IRQ
use can not be determined. That IRQ is then unavailable for other use.
If you have a card that uses Edge triggering set this line to use
"Edge
I
Auto" and the BIOS will automatically handle IRQ routing.
When you're finished making settings for this screen, press the
<Esc> key to go back to the main screen.
