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

# NAME

`xxboot` — LANDISK-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.

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.

`xxboot` must be installed by installboot(8).
