That is why I want to do a "Poor Man's Install." I do not want to do a full install , just for the sake of convenience when it comes to uninstalling if there is a problem. Or if for whatever reason I want to free up disk space it would be far easier just to delete all the KNoppix files "by hand" instead of doing a full strength uninstall. I cannot boot from CD on my PC so when I run the live CD I use floppies to boot. What I want to do is get into my grub menu , see the three options ( Red Hat, Win , Knoppix ) and then have the option to run Knoppix and to run Knoppix without having to use floppies to boot . But Knoppix must not be fully installed. Only the main program file must be on of my HD ( fat 32) partitions. As I said I do not have the "iso" file on my CD , just isolinux and the 700Mb "program file."
I've run the Live CD via floppies on my system and it works fine and I can read / write to both my win98 ( hda1) and Red hat (hda2) filesystems, which is exactly what I want. But like I said , for the sake of convenience I do not want Knoppix fully installed, I just want the PMInstall with the option in grub when I load.
Just to sum up, I'm just messing about on an old 500Mhz machine with 128 RAM and 20Gb HD which was my lab machine from about 7 years ago and am just curious to see what systems I can run on it.
There is certain software which runs fine in Knoppix and is precompiled and included which I do not have in Red Hat and which would be a pain to install as I would have to run around all over looking for dependencies and libraries when it comes to compiling and installing.
Thanks for all the advice. I'll keep you posted to let you know how much I mess up !!!
