Interrupt 19 Capture
Interrupt 19 is the software interrupt that handles the boot disk function. When this
item is set to Enabled, the ROM BIOS of a host adaptor will "capture" Interrupt 19
at bootup and allow the drives that are attached to the host adaptor to function as
a bootable disk. If this item is set to Disabled, the ROM BIOS of the host adaptor
will not capture Interrupt 19, and the drives attached to the adaptor will not function
as a bootable device. The options are Enabled and Disabled.
Watch Dog Function
If enabled, the Watch Dog Timer will allow the system to reboot when it is not ac-
tive for more than 5 minutes. The options are Enabled and Disabled.
Power Button Function
If this option is set to Instant_Off, the system will power off immediately as soon
as the user presses the power button. If this option is set to 4_Second_Override,
the system will power off when the user presses the power button for 4 seconds or
longer. The options are Instant_Off and 4_Second_Override.

Use this feature to set the power state after a power outage. Select Power-Off for
the system power to remain off after a power loss. Select Power-On for the system
power to be turned on after a power loss. Select Last State to allow the system to
resume its last state before a power loss. The options are Power-On, Power-Off
