To summarize, the Linux kernel for the HW400c/2 is installed on a host system that

the host system in the /opt/gentoo/ directory and must be made available
HW400c/2 board via NFS. After correctly configuring the network interface on the
HW400c/2 with U-boot (the Boot ROM program), the Gentoo Linux kernel is
downloaded to the HW400c/2 board using tftp. You can then boot the Linux kernel
which mounts the NFS root file system. The PPC version of the Gentoo Linux
distribution contains the necessary PPC architecture to allow the kernel and all
drivers to be compiled natively on the HW400c/2, eliminating the need to for a cr
