This readme instructs how to build busybox v1.00 and how to install it on Mainstone III.

1. Prerequisites
1.1 build tools
	Linux version:	RedHat 9
	Tool chain:	arm-linux-gcc

1.2 build targets
	version:	busybox v1.00

2. How to build?
% tar xvjf busybox-1.00.tar.bz2
% cd busybox
% cp ../busybox_config .config     NOTE: You can edit .config to choose your cross compiler by "CROSS_COMPILER_PREFIX".
% make oldconfig		   NOTE: You can change your settings by "make menuconfig".
% make

3. How to install?
% tar xvjf rootfs_base.tar.bz2 -C /path/to/rootfs/
% make install PREFIX=/path/to/rootfs/ NOTE: bin, sbin, usr/bin, usr/sbin directory will be created or overwritten.
% cd /path/to/rootfs/
% ln -s bin/busybox linuxrc

4. How to test?
% service nfs restart
% vi /etc/export		NOTE: Add lines like this "/workspace/rootfs/       *(rw,async,no_root_squash)"
% exportfs -rav

Then build a kernel whose kernel command line is specified like this to boot rootfs from nfs server, the rootfs is ok if you can login successfully.
CONFIG_CMDLINE="root=/dev/nfs nfsroot=192.168.1.100:/workspace/rootfs/ ip=192.168.1.101:::::: console=ttyS0,115200 mem=64M"
