If the BOIS ATA/IDE Configuration is set to Extended, the bios finds my

Legacy the bios finds the hard drive but not my CDROM drive. The hard
drive is on IDE -1 as master (or stand alone, makes no difference) and
the CDROM is on IDE-2 as master. Swapping cables didn't help. The two
units are mounted too far apart to make one master and the other slave
on the same IDE port.
Assuming that you are planning on booting from the hard drive, set the
BIOS so that the hard drive is recognized. The fact that the BIOS does
not recognize the existence of the CDROM should not matter. Once it has
booted (unless things have changed since I started using linux about 14
years ago) linux does not use the BIOS and should detect the CDROM drive
even though the BIOS does not.
Back in the days before I found linux, I had a hard drive that
apparently stopped working just because there was a lightning strike on
a transformer about 1/4 mile from our trailer while I was booted up and
remotely logged into another system. The box would not even boot if the
drive was installed and listed in the BIOS setup, even if I was not
trying to boot from that drive. I removed the drive, but did not get
rid of it because I am a pack-rat.
Then I started using linux and, at some point, decided to see if there
was any chance that I could boot into linux with the drive installed, in
an attempt to salvage any of the data on the disk. As it turned out, if
I listed the drive in the BIOS setup then the system would not boot, but
if I did not list the drive then the system would boot just fine from
another drive and linux, having booted, ignored the BIOS and found the
drive and was able to read everything from it that I wanted. By then, I
had recreated, or regenerated any data that I actually needed from the
drive, so I did not really need to retrieve any data, but it did give me
more available disk space. Disk space is good!
