MS-9149 ATX Server Board
System Configure Jumper: J3
The J3 jumper det ermines which mode the system will enter while pow-
ered on. During
Normal Mode
, the system will enter the assigned OS as usual.
During
Configure Mode
, the system will directly enter BIOS setup utility. This
enables you to modify the BIOS configurations. During
Recovery Mode
, you
have to insert certain boot disk into t he floppy drive before po wering on the
system. After powered on, the system will read the boot disk and enter DOS.
This enables you to update the BIOS with a Flash utility if necessary.

MSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off.
Then return to 1-2 pin position. Avoid clearing the CMOS while
the system is on; it will damage the mainboard.
Cle ar CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external
battery to keep the data of system c onfiguration. With the CMOS RAM, the
system can automatically boot OS every time it is turned on. If you want to
clear the system configuration, use the JBAT1 (Clear CMOS Jumper ) to clear
data. Follow the instructions below to c lear the data:

The LAN controller integrated on the motherboard varies depending on
the mode l you have purc hased . Th e defa ult factory set tings are prope rly
configured for optimal system performance and thus should be left unchanged.

PCI Slots
Five PCI s lot s allow you to inse rt the expa nsion c ards to mee t yo ur
needs. When adding or removing expansion cards, make sure that you unplug
the power supply first. Meanwhile, read the documentation for the expansion
card to ma ke any necessary h ardware or software settings for the expansion
card, such as jumpers, s witches o r BIOS co nfiguration. Three PCI slot s are
convent ional 32-bit PCI bus slot s and the ot her two are 64-bit PCI bu s (also
called
PCIX
) slots.
32-bit PCI bus
: The bus has 32 data lines and runs at 33MHz.
64-bit PCI bus
: The bus has 64 data lines and runs at 33, 66MHz. With
twice data lines and much faster PCI clock, the 64-bit PCI bus increases
the throughput and overall system performance.
The motherboard provides two PCI-X 64bit/66MHz and three PCI 32bit/
33MHz slots.
