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
removing expansion cards, RAM or other system peripherals,
otherwise your mainboard and RAM might be seriously damaged.
Note:
This manual is suitable for P5I945P(G) series of mainboards. Each

Introduction
P5I945P(G)series of mainboards utilizeIntel® 945P/945G+ ICH7 chipset,
providing a fully compatible, high performance and cost-effective ATX
platform. P5I945P(G) supports next generation graphics interface: PCI
Express x 16.The new integrated technologies, together withAC’97 audio
(6-channel) or High DefinitionAudio(8-channel), 4 SATA(option), 8 USB
2.0 ports andATA100/66, give customers an advanced, multimedia solu-
tion at reasonable price. It provides 533/800MHz host bus speed to sup-
port Intel LGA775 processors. Suspending to RAM(option), the optimal
implementationoftheAdvancedConfigurationandPowerInterface(ACPI)
specification, makes the PC’s power consumption drop to the lowest
possible level and enable quick wakeup.

Theconnector connects tothe case’s IDE indicatorLED indicating theactivitystatus 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.
Power LED Connector (PWR_LED)
Whenthesystemisin S0 status, the LED is on. When the system is in S1 status, the LED
is blink; When the system is in S3(option), S4, S5 status, the LED is off. The connector has
anorientation.
ATX 12V Power Supply Connector & Power Switch (POWER Switch)
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. P5I945P(G)
series mainboard only supportATX12V power.

Audio Interface(F_AUDIO)
For the mainboard supportingALC655, The audio interface provides two kinds of audio
output choices: the FrontAudio and the RearAudio. Their priority level is as sequence.
When the FrontAudio is available, the RearAudio( in-case speakers ) will be cut off.An
onboard amplifier is provided for the earphone. When the FrontAudio is absent, Pin5 and
Pin6, Pin9 and Pin10 must be short connected.
For the mainboard supportingALC880, please use HDAfront audio panel for F_AUDIO
