From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.9) Gecko/20020311 Description of problem: The installation CD does not appear to be bootable, when inserted in ATAPI Device attached to Promise Ultra133-TX2 adapter on system boot. My other ATAPI device attached to motherboard controller boots from the CD just fine. Just as a Windows Xp installation CD boots fine in the promise attached device. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. RH 7.2.93 Media in ATAPI device on Promise Ultra133-TX2 controller 2. Boot System Actual Results: My already installed system started Expected Results: The RH installation should have started instead Additional info: According to Promise, they "don't allow booting from ATAPI devices". But like i descriped above, my Windows Xp CD boots without any problems, so that can't be entirely correct.
Did you Red Hat CD boot on any other systems, or if you move the CD to a different IDE adapter? If Promise says this is not supported then there is very little we can do.
The CD boots fine on other systems or even when used in the exact same device, but on another controller. I know, that if promise doesn't support booting from ATAPI devices, they are not likely to be very helpful locating the problem. But it still puzzles me that the Windows Xp CD does in fact boot from that device on that controller. If you are unable to fix the problem, then I guess thats just too bad... But at least now you know... a litte something to the "known problems" list.
An idea : - windows NT4 CD is using a native ( non-emulation ) boot mode, maybe XP does the same - redhat CD uses a floppy-emulation boot mode - boot from the Promise card is controlled by the Promise BIOS - boot from the motherboard controller is controlled by the motherboard BIOS Maybe the Promise BIOS supports native CD booting , but no emulation modes ?
Perhaps the Promise BIOS for that controller does not support the el Torrito standard for booting from CDs. In any case since this is documented by Promise to not work, and we are not going to change our process from using el Torrito, I don't see this as an issue we'll be addressing.
At least now it's a know "problem" - I'll get my Red Hat Linux installed anyway ;-)
