Red Hat Bugzilla – Bug 220001
IDE-CD is falsely detected as primary BIOS disk
Last modified: 2007-11-30 17:07:39 EST
Description of problem:
RHEL5 installation fails on a system without IDE disk and IDE CD-ROMbecause the
CD drive is "used" by anaconda as primary disk for installing the Grub MBR
Version-Release number of selected component (if applicable):
How reproducible: always
Steps to Reproduce:
1. Install RHEL5RC3 on a system with SCSI disks and IDE CD-ROM. Network
installation method (NFS) was used in our case, I don't know if that's a
necessary criterion for the bug to appear.
2. Skip the "advanced bootloader options" menu
3. Complete installation
System is unable to boot (no boot loader installed)
Correct boot loader installtation
If the advanced bootloader options menu is used during installation, the IDE
CD-ROM is listed on top. It is possible to correct the "BIOS disk order" here
and force correct boot loader installation. However it seems awkward that a CD
drive is even offered for boot loader installation.
The BIOS EDD information as provided by the "edd.ko" module is correct.

Anaconda error from rescue system
When trying to fix this problem with the installation CD in rescue mode, the
attached error occurs, making matters worse. The MBR can only be fixed by
booting in installation mode again and using the command line.
