Great so far the requirements I'm thinking include:

a byte for the boot method:
0 - firstboot or CMOS cleared(default)
1 - Manual Boot
2 - Command Line boot
3 - filo.conf boot

a byte for auto boot time out specified in seconds

and the rest for ASCII text which would include one of two things:

a kernel command line


a pointer to filo.conf on the hard drive

What do you think?
