Altboot is a functional bridge to fill the gap between a NAS product
custom bootloader and the NetBSD kernel startup environment. Altboot
irons out and rectifies erroneously configured HW by product
bootloaders and prepares a sane runtime better suited for booting

U-Boot/PPCboot, where the altboot.bin image is stored in an unoccupied 128KB
section of the target's HW NOR flash. Combined with standard
U-Boot/PPCboot functions, it is possible to boot a NetBSD kernel off
it right after power-on, without the help of manual intervention. Note
that the original U-Boot/PPCboot still remains useful and altboot works
as a functional extension for them.
In case the firmware was crippled by the vendor so that it only boots
Linux U-Boot images (D-Link), you can still use altboot by uploading
altboot.img instead of the Linux kernel.
Altboot hands the following bootinfo records to the NetBSD/sandpoint
kernel.
