Fan1 ~ Fan 6 Reading

This feature displays the fan speed readings from fan interfaces Fan1 through Fan5.

CPU Vcore, AVCC, 3.3Vcc, 12V, V_DIMM, 5V, -12V, 3.3Vsb, and Vbat

ACPI Configuration

Use this feature to configure Advanced Configuration and Power Interface (ACPI) power management settings for your system.

High Performance Event Timer

Select Enabled to activate the High Performance Event Timer (HPET) that produces periodic interrupts at a much higher frequency than a Real-time Clock (RTC) does in synchronizing multimedia streams, providing smooth playback and reducing the de- pendency on other timestamp calculation devices, such as an x86 RDTSC Instruc- tion embedded in the CPU. The High Performance Event Timer is used to replace the 8254 Programmable Interval Timer. The options are Enabled and Disabled.

PS2 KB/MS Wakeup

This feature is used to awaken the system from Standby mode by a PS/2 mouse or PS/2 keyboard. This must be enabled in the system level and Operating System (O/S) as well, if supported).

S1 (OS Control) - Enables system wake up from S1 (default). S5 (OS Control) - Enables system wake up from S1/S3/S4/S5.

Force Enable - Wake up support is always enabled regardless whether it is disabled in the O/S.

Force Disable - Wake up support is always disabled regardless whether it is enabled in the O/S.

ACPI Aware O/S

Enable ACPI support if it is supported by the OS to control ACPI through the Operat- ing System. Otherwise, disable this feature. The options are Yes and No.

ACPI APIC Support

Select Enabled to include the ACPI APIC Table Pointer in the RSDT (Root System Description Table) pointer list. The options are Enabled and Disabled.

APIC ACPI SCI IRQ

When this item is set to Enabled, APIC ACPI SCI IRQ is supported by the system. The options are Enabled and Disabled.
