Each PCI Slot has three option fields:
The first field is the "Latency Timer"
setting.
Do not change the
"80
PCI
Clock"
setting. The default enables maximum
performance.
The "Using IRQ" field assigns a system IRQ to a PCI slot. An
"NA"(Not
Assigned) setting means
no
IRQ is assigned to that slot.
The default IRQ settings are:
Slot 1:
10
Slot 2:
11
Slot 3:
NA
NCR:
9
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:
l. 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 controller
which, if
enabled,
automatically uses these two IRQs
.
For an
IDE card that only
uses
one
channel,
se 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 uses 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 be completely compliant with the PCI auto-
detection specification that allows
"Level
(Auto)" to automatically
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 (By JPx-x)" and set the
relative
jumpers correctly.
When you're finished making settings for this screen, press the
