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

You might have disabled ROM BIOS because of which 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.

This interrupt can be used to determine if the drive door is open, if the disk is formatted, if the disk is write-protected, and many other conditions. The code generated for this is smaller than a similar program using ON ERROR GOTO statements to trap disk errors.

Interrupt 19 with function 0 (reset disk system) should be called after a failed floppy disk Read, Write, Verify, or Format request before retrying the operation.
