Re: OK to install across 2 HDs?
I am writing my questions in between the text, if anyone can
answer them I would appreciate it.

Why are you not using hda and hdb? what determines which one
you use?
I have two HD's. Right now only one is hooked up -- it is my
hda, a 1.6G Western Digital, running Redhat. I wish to hook up
in addition a 340 Meg Connor. I would like that to be the
slave so that I can keep my WD stuff where it is. I want to
install Debian on the 340 Meg drive until I convince myself if
I want Debian on the 1.6G drive. I would like to boot up on
either one. How do I arrange that? The second one would be
hdb, would it not? . Each drive will be partitioned by using
linux fdisk, and each drive has a small DOS partition on hda1
and hdb1. I do not wish to use both disks for one distribution
just yet (I understand the merit of doing that, however). I
want to get Debian running on my "test" 340 meg drive, without
disturbing my "running system". Can I get lilo to boot from
either drive? How?

I don't understand this statement. What exactly is the relation
between hda, hdb, and hdc? Do you have one controller
that runs two HD's? What is your hardware configuration?
I have a controller card, el-cheapo $19.00, that controls 2 IDE
HD's, 2 Floppies, 2 Serial Ports and 1 Parallel Printer port.

These are good ideas. I like this, and when I get past my
"experimental" phase I will do this also. Thank you.

Sorry for my elementary questions. Any advice will be
appreciated. Thank you for your post, Pete.
