Caution
Caution
Be sure to add some Silicone Grease between the CPU and the
heatsink to keep them fully contacted to meet the heat sink require-
ment.
Be sure to unplug the AC power supply before adding or re-
moving expansion cards, RAM or other system peripherals, other-
wise your mainboard and RAM might be seriously damaged.

Introduction
P4I848P series of mainboards utilize Intel® 848P + ICH5
(ICH5R) chipset, providing a fully compatible, high perfor-
mance and cost-effective ATX platform. The new integrated
technologies, together with AC’97 audio(2/6-channel), 8
USB, 2 SATA, and ATA100/66/33, give customers an
advanced, multimedia solution at reasonable price. It pro-
vides 400/533/800MHz host bus speed to support Intel®
Pentium 4 socket 478 processors and the DDR266/333/
400 memory. It also provides advanced features such as
Wake up by USB devices, Wake-on-Modem, ACPI and Key-
board Password Power-on functions. Suspending to RAM,
the optimal implementation of the Advanced Configuration
and Power Interface (ACPI) specification, makes the PC’s
power consumption drop to the lowest possible level and
enable quick wakeup.

This section covers External Connectors and Jumper
Settings. Refer to the mainboard layout chart for locations
of all jumpers, external connectors, slots and I/O ports. Fur-
thermore, this section lists all necessary connector pin as-
signments for your reference. The particular state of the
jumpers, connectors and ports are illustrated in the follow-
ing figures. Before setting the jumpers or inserting these
connectors, please pay attention to the direction.

Hard Disk LED Connector (HD_LED)
The connector connects to the case’s IDE indicator LED indicating the activity status of IDE
hard disk. The connector has an orientation. If one way doesn’t work, try the other way.
Reset Switch (RESET)
The connector connects to the case’s reset switch. Press the switch once, the system
resets.
ATX 12V Power Supply Connector & Power Switch (POWER SW)
The power switch (POWER SW) should be connected to a momentary switch. When powering
up your system, first turn on the mechanical switch of the power supply (if one is provided),
then push once the power switch. When powering off the system, you needn’t turn off the
mechanical switch, just push once the power switch.
If you change “Soft-off by PWR-BTTN” from default “Instant-off”
to “Delay 4 Sec” in the “POWER MANAGEMENT SETUP” sec-
tion of the BIOS, the power switch should be pressed for morethan
4 seconds before the system powers down.

Wake-Up On Internal Modem (WOM)
Through this function, the system which is in the suspend or soft-off status can be waked up
by a ring signal received from the internal modem. When this function is used, be sure an
internal modem card which supports this function is used. Then connect this header to the
relevant connector on the modem card, set “Power on by Ring/LAN” as Enabled in the
“Power Management Setup” section of the CMOS SETUP. Save and exit, then boot the
operating system once to make sure this function takes effect.
