Thanks for your response:
(1) I think the CD reader would work OK at installation.
I actually installed from the hard disk,
but both the Rescue CD and the CD I made with "mkbootdisk --iso"
seem to work fine.
(2) In what follows, I am always running kernel 2.6.9-1.667
which came with FC-3,
with the grub stanza
================================
title Fedora Core (2.6.9-1.667)
root (hd0,1)
kernel /vmlinuz-2.6.9-1.667 ro root=/dev/hda3 ide1=0x180,0x386
initrd /initrd-2.6.9-1.667.img
================================
If the CD reader is attached at boot-time,
the system hangs after I log in.
Ctrl-Alt-Delete and Ctrl-Alt-F1 do not work;
I have to stop the machine (badly) by pressing the power button.
(3) If the CD reader is not attached at boot-time,
then I am able to login as usual.
The following is an excerpt from /var/log/messages

===============================================
4) I notice that ide0 and ide2 are mentioned here.
If I replace "ide1=..." with "ide2=..." I get the same outcome,
except that now ide0 and ide1 are mentioned.
(5) I note that the cdrom module is not mentioned by lsmod;
I assume this is in the kernel.
However, I get exactly the same outcome on a vanilla 2.6.9 system
with the modules
======================================
ide_cd 37376 0
cdrom 38044 1 ide_cd
======================================
Are any other modules, eg SCSI, required?
(6) Would it help if I installed 2.6.10-rc2 or 2.6.9-ac8 ?
