XXBOOT(8) System Manager's Manual (landisk) XXBOOT(8)

NAME

xxbootLANDISK-specific primary boot loader

DESCRIPTION

This small program, residing in the reserved sectors at the beginning of the root file system of the system, is responsible for loading the second-stage boot(8) program (typically /boot), which in turn will load the kernel.
To install (or update) the xxboot program, use disklabel(8) with the -B switch.
When xxboot receives control from the master boot record (MBR) it will print a banner:
OpenBSD MBR
followed by a little twiddler while reading the second-stage boot.
