Thanks A, this has come in handy today.

An FYI for others making changes to minirt2*.gz, if you end up with a file larger than you started with, you must rerun lilo if you test your changes with a bootable partition. lilo reserves an Initial Ram Disk exactly the size of minirt. If you put a larger file in the boot directory and try to boot from it, you get nothing; no error message. The screen says Loading kernal but nothing else happens. I expect if you put a smaller minirt file in the boot directory it works fine.
