Interrupt 19 Capture
Interrupt 19 is the software interrupt that handles boot disk functions. When this item
is set to Enabled, the ROM BIOS of the host adaptors will "capture" Interrupt 19
at bootup and allow the drives that are attached to these host adaptors to function
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. The options are Enabled and Disabled.
