Installation
Step 4. Install expansion cards
The motherboard has 1 AGP slot, 4 PCI slots and 3 ISA slots.
1. Read the instruction document of the related expansion card before inserting the
expansion card into the computer.
2. Press the expansion card firmly into the expansion slot on the motherboard.
3. Make sure the metal contacts on the card are correctly seated in the slot.
4. Replace the screw to secure the slot bracket of the expansion card.
5. Install related driver for the operating system you use.
Note1: Only AGP card with 1.5 volts can be used in this M/B (any card supporting AGP
4X or higher). Using 3.3 volts AGP card (AGP 1X or 2X cards) will damage your
motherboard. For AGP card voltage specification, please check the AGP card manual or
contact your AGP card manufacturer.
Note2: When you use an AGP add-in card on the P4I845GEISA mainboard, the onboard
VGA will automatically be disabled. It’s not possible to use onboard VGA and an AGP
add-in card at he same time. For both versions (P4I845PEISA and P4I845GEISA) note
that when using a PCI VGA card, make sure that the “Init Display setting” is set to PCI
slot instead of onboard/AGP. Also, note that when using a PCI VGA card the on chip VGA
setup option can be used to disable onboard VGA.
CMOS Clear (JP5)
In some cases the CMOS memory may contain wrong data, follow the steps below to
clear the CMOS memory.
1. Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5. This
jumper can be easily identified by its white colored cap.
2. Then put the jumper back to 1-2 to allow writing of new data into the CMOS memory.
