Description Doug Chapman 2007-07-31 20:28:45 UTC
Description of problem:

From issue-tracker:
On my SandDune (Superdome/sx2000), I have a _lot_ of disks, a lot of networking
cards, and a lot of various Linux installs.  I have 10 bootable entries, as follows:

[root@worm0 ~]# efibootmgr
BootCurrent: 0008
Timeout: 10 seconds
BootOrder: 0000,0005,0004,0008,0009,0003,0001,0007,0002,0006
Boot0000* EFI Shell
Boot0001* Gbit Boot NIC
Boot0002* USB Optical/DVD drive
Boot0003* 10GigE NIC Boot
Boot0004* RHEL5 Server
Boot0005* RHEL4u4 AS
Boot0006* SCSI Optical/DVD Drive
Boot0007* Smart Setup from USB/HDD
Boot0008* RHEL4.5 AS (snap#5)
Boot0009* SLES10
[root@worm0 ~]#

Now the problem is that if I install a NEW copy of RHEL4.5 (snapshot 5), the
installer creates an entry named "Boot000a" (with a lower-case 'A').  If you
boot to RHEL5 and run "efibootmgr", it complains about the lower-case 'A' and
suggests the user fix that by changing the boot entry via EFI.

The problem with this: EFI doesn't recognize it.  So, RHEL4.5 needs to ensure
that Hex-digits a-f are UPPER-CASE when it creates boot entries.

It appears this was fixed upstream and is already fixed in RHEL5.  I will
provide a patch.
