PCI-X Bus Speed Setting
(P4DLR+/P4DLR)
Jumpers P2 and JP4 are used to set
the speed for the PCI-X bus on the
P4DLR+ and P4DLR. The default
setting is PCI 66 MHz (the other set-
tings are to support future PCI-X
cards.) See the table on the right
for jumper settings.
33 MHz PCI Enable/Disable
If you wish to use 33 MHz PCI
c a r d s , c l o s e J 2 9 ( J P 4 o n t h e
P4DLR+/DLR) to force the P1 bus
(P4DL6) or single slot (P4DLR+/DLR)
to run at 33 MHz. See the table on
the right for jumper settings.
Note : if you force the slots(s) to 33
MHz, you must set the PCI-X bus
speed jumpers (above) to the low-
est speed.

PCI-X Bus Speed Setting
(P4DL6)
Jumpers P1, P2, S1 and S2 on the
P 4 D L 6 a r e u s e d t o c h a n g e t h e
speeds for the four PCI-X buses.
See the table on the right for jumper
settings.
PCI-X Buses:
S1: Bus for PCI-X slot #1 and SCSI
P1: Bus for PCI-X slots #2 and #3
S2: Bus for PCI-X slots #4 and #5
P2: Bus for PCI-X slot #6 and G-bit
LAN
Notes : (1) If two cards are used in
slots that share a bus, both slots
will run at 100 MHz.
(2) If SCSI is used, slot #1 will be
limited to 66 MHz operation.
