efibootmgr uses lower case hex values which violates EFI spec

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. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
