Interrupt 19 Capture

Common Options : Enabled, Disabled

Quick Review

Interrupt 19 is the software interrupt that handles the boot disk function. It is typically handled by the motherboard BIOS although it can also be handled by the optional boot ROM BIOS in some IDE/SCSI host adaptors.

When enabled, this BIOS feature allows the ROM BIOS of these host adaptors to "capture" Interrupt 19 during the boot process so that drives attached to these adaptors can function as bootable disks. In addition, it allows you to gain access to the host adaptor's ROM setup utility, if one is available.

When disabled, the ROM BIOS of these host adaptors will not be able to "capture" Interrupt 19. Therefore, you will not be able to boot operating systems from any bootable disks attached to these host adaptors. Nor will you be able to gain access to their ROM setup utilities.

If you use separate IDE/SCSI host adaptors, you should enable this BIOS feature if you wish to boot from any drive attached to your host adaptors. It will also allow you to gain access to any ROM-based setup utilities.

However, if you are not using any separate IDE/SCSI host adaptors, it's recommended that you disable this BIOS feature.
