Akemi,

Thanks for the information.  I did visit the link and found what I 
interpreted as a replacement iso for the first disk of 4.  Did I 
misinterpret something ?  I downloaded disks 2 through 4 from the Ga. 
Tech mirror and burned them as well, all apparently without error.
However, when I attempted to run a media check from "i586 text nousb"
the first disk passed but the others resulted in "unable to find install 
image on /tmp/cdrom" (or something close to that, I am quoting from 
memory).  I looked at the disks and they appear to be OK, and I burned 
them with the same commands I used for disk 1.  Does this mean I needed 
to gets disks 2 through 4 elsewhere ?  Only disk 1 of the set was on the 
link I visited.

Another question, and perhaps I need to google this more but thought I'd 
ask:  On the system I am trying to install this I already have on hda
msdos and RH9.  I have a large disk on hdc, however, with lots of free 
space.  It appeared that by telling the installation program to use only
hdc I could successfully put CentOS there, but when it came time to tell
grub what other systems to boot I it recognized dos on hda1, but I could 
find no way to add RH9 on hda2.  It seemed that I was limited to only 
two operating systems.  Is there a way around this ?

(If not I intend to physically swap the hard disks and just install on 
the new hda, keeping stuff on the old hdc for reference).  But if it is 
possible to keep the two existing systems on hda and put CentOS on hdc, 
and have grub on the mbr of hda control the boot I'd like to do that.

Thanks,
