Okay this is going a bit over my head now. I'm gonna give it one more go. I got Grub4DOS and installed it on the "whole MBR" of hd0 using Grub4DOS Installer. I'm actually a little concerned I jumped into it and my PC won't reboot the next time

Let's see.
1. plpbt.bin is in C.
2. menu.lst contains grub4dos's menu?
3. Definitely need to add grldr? or grldr.mbr?
4. Don't I have to add something to boot.ini?
My basic idea of a menu.lst
color blue/green yellow/red white/magenta white/magenta
timeout 30
default /default
title PLoP Boot Manager
fallback 1
<What goes here?>
*EDIT: haha! Just what I thought. It didn't boot up. Fortunately, it asked me to boot from the previous mbr.
