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 the host adaptors will "capture" Interrupt
19 at boot and allow the drives that are attached to these host adaptors to func-
tion as bootable disks. If this item is set to
Disabled
, the ROM BIOS of the host
adaptors will not capture Interrupt 19, and the drives attached to these adaptors
will not function as bootable devices.
