The systems covered in this guide utilize the following specialized functions built into the LPC

47B367 I/O Controller:

♦ Power/Hard drive LED control – The I/O controller provides color and blink control for the

front panel LEDs used for indicating system events as listed below:

System Status Power LED HD LED

S0: System on (normal operation) Steady green Green w/HD activity

S1: Suspend Blinks green @ 1 Hz Off

S3: Suspend to RAM Blinks green @ 1 Hz Off

S4: Suspend to disk Blinks green @ 0.5 Hz Off

S5: Soft off Off - clear Off

Processor not seated Steady red Off

CPU thermal shutdown Off (system powers down) Off (system powers down)

ROM error Blinks red @ 1 Hz Off

Power supply crowbar activated Blinks red @ 0.5 Hz Off

System off Off Off

NOTE:

[1] Later systems using PCA#s 011305, 011308, or 011311 will power down for this condition.

♦ Intruder sensing – Used on Small Form Factor and Desktop models, battery-backed D-latch

logic internal to the LPC47B367 is connected to the hood sensor switch to record hood

(cover) removal.

♦ Hood lock/unlock – Used on Small Form Factor and Desktop models, logic internal to the

LPC47B34x controls the lock bar mechanism.

♦ I/O security – The parallel, serial, and diskette interfaces may be disabled individually by

software and the LPC47B367’s disabling register locked. If the disabling register is locked, a

system reset through a cold boot is required to gain access to the disabling (Device Disable)

register.

♦ Processor present/speed detection – One of the battery-back general-purpose inputs (GPI26)

of the LPC47B367 detects if the processor has been removed. The occurrence of this event is

passed to the ICH2 that will, during the next boot sequence, initiate the speed selection

routine for the processor. The speed selection function replaces the manual DIP switch

configuration procedure required on previous systems.

♦ Legacy/ACPI power button mode control – The LPC47B367 receives the pulse signal from

the system’s power button and produces the PS On signal according to the mode (legacy or

ACPI) selected. Refer to chapter 7 for more information regarding power management.
