	Finally got around to this today. It worked; many many thanks! I 
had to mess around a while in some places -- perhaps because I've only 
been running linux since RH7; I got two or three books with media for 
RH6, but could never manage to install it ....

	For us hoi polloi, you might want to mention using "quit" instead 
of "exit."

	I chewed a while on that, too. Finally decided to start with 
switching the sda and hda locations -- luckily.

	Chewed some more, before I realized I had to go through the 
chroot routine; I had never realized you could invoke grub as a command 
on a booted and running machine -- d'uhhh ....

	The machine in need had only one hard drive; so I skipped the 
second half.

	How do you get into anaconda -- is there a way without a rescue 
disk?

	Hadn't ever heard of dailypackage; many thanks! Heavy stuff, at 
least for subtechnoids, but very well written. Kudos & thanks to the 
author!
