Log:
Add string support to nvramtool.
To add a string to your cmos.layout, you need to specify type 's':
#start len type unused name
416 512 s 0 boot_devices
With this patch you can do
$ nvramtool -w boot_devices="(hd0,0);(hd2,1);(hd3)"
And FILO will attempt to load a menu.lst from any of these devices in that
order.
The patch is not exactly pretty, but a cleaner solution might have resulted in
a complete rewrite of the tool, which I did not want.
