beta iso will not boot

From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020625 Description of problem: limbo beta iso will not boot on my pentium box (p100 with 32 megs ram). Redhat 7.3 disks boot fine on this machine. I have successfully booted several newer boxes with the limbo disk I have created, and the mediacheck command shows the disks as good. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. boot p100 32 Meg box with limbo cdrom 1 2. cdrom boot failure. Expected Results: I expect to get a linux installer text prompt similar to what I say on boot a 7.3 iso. Additional info:
We are now using isolinux to boot CDs. If you could download the test image at http://people.redhat.com/~katzj/debugiso.bin and burn it to a CD, what are the last lines of output before it hangs?
using the aformentioned debugiso....my p100 system boots just fine it seems. I can boot in text mode using the debugiso image...i get the language and keyboard selection dialogs..then I'm told to insert the redhat boot cd...but when i swap out the debugiso disk for the redhat limbo disk 1..i get the error message saying there was a mismatch between the first and second stages of the boot process...and the installer tells me it's going to reboot my system...obviously there is something incompatible with the debugiso and the limbo disk...I dont know if this is a problem or expected behavior for the debugiso. I'm not sure what's wrong, there's nothing obvious in any of the virtual terminal #2 messages that would suggest an error. I'm going to download and burn the limbo disk1 iso again just to double check..but since the iso boots in "new" machines I'm doubtful there is a problem with how I burned the image...but I could be wrong..better to double check on my end just to make sure. Any other suggestions?
Hmm.. the only differences between the isolinux in the two versions is supposed to be debug messages. I'll have to double-check a diff to ensure there's not anything else. It's entirely expected that you won't be able to install after booting that CD because I just made that image a few weeks ago when I was first testing out isolinux and so it's keyed to a tree from that time-frame. Verifying that the actual limbo CD doesn't boot would be great.
Hi again... I just reburned the first disk iso image...still doesn't boot on my p100 box with 32 megs of ram....i booted the iso and ran mediacheck on one of my newer boxes...so as far as I can tell its a good disk with a good image..but the image isnt bootin on my p100 box. All i get is a bios message saying boot from cdrom failed. So it looks like the iso really does have a problem booting on older systems. to recap 1) limbo disk 1 iso will not boot on my p100 32meg system 2) the debugiso image boots on the p100 32meg system 3) redhat 7.3 isos boot without a problem on the p100 as well 4) limbo disk 1 iso will boot on the athlon >= 1GHz systems I have on hand along with my amd k6-2 400 MHz system Any other ideas? I'm going to move on and try to boot with one of the floppy images and do a network install...see if that gets me anywhere until this bug in the cdrom image is nailed down. I'd like to move on and find some application level bugs for you guys to fix, but if you have any more ideas for me to try concerning this iso boot problem I'm all ears. -jef
*** Bug 69110 has been marked as a duplicate of this bug. ***
I originally reported this as bug 69110 I have tried booting the old Gateway Pentium P-75 from the null-7.3.94 cd#1, but is still fails, as it seems it is the same isolinux as the limbo-7.3.92 ! I have burned the image debugiso.bin to cd & tried that. It reports: ISOLINUX 1.75 2002-06-14 Copyright (C) 1994-2002 H. peter Anvin isolinux: Starting up, DL=00 isolinux: Loading spec packet failed, trying to wing it... isolinux: Failed to locate CD-ROM device; boot failed.
Does Phoebe work any better?
Ok, I have tried with 'Phoebe 8.0.92', but it is no better: ISOLINUX 2.00 2002-10-25 isolinux: Loading spec packet failed, trying to wing it... isolinux: Failed to locate CD-ROM device; boot failed.
This is a BIOS bug, then and you're going to have to use boot floppies for this machine.
