Buffalo WHR-G54S Tutorials

Buffalo WHR-G54S von einer SD-Card Booten.

mmc.o für den Buffalo hier

# mount it
mount -t ext3 /dev/scsi/host0/bus0/target0/lun0/part1 /mnt
# now, we need to mount the root contents somewhere so we can copy
# them without copying /mnt and /proc to the new usb device
mkdir /tmp/root
# if you're using squashfs, you want to copy the squashfs contents,
# not the jffs2 symlinks, so use the command:
mount -o bind /rom /tmp/root
# if you're using jffs2 then use the command /
mount -o bind / /tmp/root
# now /tmp/root contains the root filesystem with no extra directories mounted
# so we just copy this to the usb device
cp /tmp/root/* /mnt -a
# and now we unmount both the usb and our /tmp/root
umount /tmp/root
umount /mnt
