Description of problem:
When I install Fairfax RC1 on PE6450 + DVD-ROM, I got this error message:
" I could not find a RedHat Linux CDROM in any of your CDROM drives..."
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.PE6450 + DVD-ROM (LG DVD-ROM DRN-8080B, ATAPI CD/DVD-ROM)
2.Install from CD
Actual Results: I can't install on PE6450 + DVD-ROM drive, by using CD-
ROM installation method.
Expected Results: Must be able to install on PE6450+DVD-ROM.
I also try to use "linux ide=nodma" at the prompt, but I get the same
result (doesn't work).
Were you able to boot from the disc?
Did you check the md5sum of the disc?
Yes, the system boots from CDROM. I also use the same disc on the other system
with CD-ROM drive, and the CD is working fine.
Have you tried making a boot floppy with the boot.img file and booting that way?
I tried to use boot.img diskette, and the result is the same.
I also tried on the other PE6450 with minimum configuration (3GB RAM), and I
got the same result. However, the same DVD-ROM is working on PE2550.
I tried RH7.1SBE, It works. Fairfax beta 3 --> no.
If you do a network install, does the drive work in the post-install environment?
After network install, I can use DVD-ROM drive to read CD, and DVD disc.
Also, I tried to install RC2, I got no luck either.

Can you send us one of the drives? We don't have any of those here....
Also, try with the 'acpi' flag to the boot kernel.
('apic', not 'acpi'. Sorry about that.)
Passing "apic" doesn't make a difference. Issue was tested on three PE6450 and
was reproduced on all.
"linux ide=nodma" is required when using a "SAMSUNG CD-ROM SN-124".
Installation on PE6450 with "Toshiba XM-7002B" cdrom exits abnormally even
when "ide=nodma" is passed.
After install RC2 by using NFS install method. I can use DVD-ROM drive.
However, there are a bunch of errors message. I will attach /var/log/messages
to this bug.

DVD-ROM error message
The same issue was reported and closed against Florence, bug # 29089.
The blacklist entry that fixed #29089 is now in the standard kernel and is
of course not backed out for this release; you can see it in the
We think that in our very latest BOOT kernels we have used a big enough
hammer to fix this problem.
Testing with boot.img from kernel 2.4.7-7 (from Rawhide) installed fine using
this DVD. More testing will be done tomorrow.
Works with Gold.
