Hey Rick,

That was it.  I was using 650MB disks, not 700MB.  Installed great.  Thanks
for the help.

Sure.  You said that the MD5 checksum of the ISO image was correct,
right?  You can run the MD5 checksum on the burned disk as well:

	md5sum /dev/cdrom

Do NOT run the checksum on the mount point (/mnt/cdrom)--do it to the
raw device.

Things to consider:

1. Don't burn at the highest speed your drive can do (you're already
doing that).

2. Make sure you use 700MB media--not 650MB media.  The ISOs completely
fill a 650MB media and the outer edge of CD-ROM media is not reliable.
Use 700MB CDRs.

3. Use only name-brand media (I use TDK or Maxell mostly).

4. Check the checksum of the burned media as shown above.

5. You can try turning off DMA operations on the CD-ROM drive during the
installation.  Assuming your CD-ROM is the primary device on the
secondary controller (or device /dev/hdc):

	boot: linux hdc=nodma

Is there a reason you're using RH9?  It reached end of life almost a
year ago and only the Fedora Legacy project supports it now.  The latest
"free" Red Hat Linux is Fedora Core 3.  FC3 should work with the 384MB
of RAM you have, although the odds are the system will do some
swapping.  I'd get the thing up to 512MB if possible.
