OPERATIONS MANUAL PPM-GX500
27
Available Options (Power Management Configuration)
BIOS PM at Boot
[Enabled],
[Disabled]
–
enables or disables APM
support at boot-up. This
provides some BIOS level APM
support for OS that do not
support the power management,
like DOS. OS that support
APM can still use the power
management features, once
booted.
*Note: APM Available must be
enabled before BIOS PM at boot will
take effect.
APM Available
[Yes] -
Allows APM aware
operating systems and
applications to control power
management features of the
PPM-GX500.
[No] –
completely disables APM
support on the PPM-GX500.
ACPI Available
[Yes] –
Enables Advanced
Configuration and Power
Interface on the PPM-GX500.
ACPI establishes industry
standard interfaces for OS-
directed configuration and power
management.
[No]–
completely disables ACPI
support in the BIOS and allows
IRQ 9 to be used for other
purposes.
*
Note
: Some operating
systems, such as Windows XP/XP
Embedded, assume IRQ 9 is
assigned to ACPI regardless of
the hardware settings.
