Updating kernel on Installation CD

[Brian Hayward]

I need to fix the APIC bug related to the DAC960 driver.  To do this I
have to update the boot/install disk for Fedora Core 4.  I've followed
the instructions for FC2 at:

http://www.techonthenet.com/linux/fc2_update.php

Everything goes well, I boot the installation disc, but it tells me
that it cannot find the installation CD in any of the cdrom drives.

Then I tried simplifying the approach (just update isolinux/* and
kernel-...i586.rpm from a pristine FC4 disc1).  The installer gave me
the same error.

Who has the expertise to help with this?  What is the installation
program looking at to determine whether a valid FC4 cd is in the cdrom
drive?

Here iso-info for the disc I created (I made it match the original
boot cd isoinfo output):

isoinfo -d -i Stentz-i386-disc1.iso
CD-ROM is in ISO 9660 format
