Red Hat Bugzilla – Bug 47288
does not boot from cd
Last modified: 2007-04-18 12:34:26 EDT
Description of Problem:
Installer will not boot from cdrom on a Toshiba Satellite 320CDS
Steps to Reproduce:
1. tell bios to boot from cd
2. power and insert disk 1
3. watch old linux installation or win startup happily
old system boots
installer for 7.1
Please note that 7.0 did *not* have this problem, just double checked right now, again original boxed set.
Do you see any error messages? At what stage does it fail? By that, I mean,
does it boot off the cdrom successfully and then fail to recognize it later? Or
does nothing happen at all?
Nothing happens, as if the cd were not in the drive at all.
Wow. There's not much I can do in the way of debugging if there's just nothing
to go on. It is possible that your cd is damaged somehow...even if it is from
the retail box. Do you have another computer you could test it on...just to see
if the cd can be read or not?
cd is undamaged, another laptop (different make/model) boots up just fine.
Also, booting from floppy and using the cd as install source works ok.
The difference between 7.0 and 7.1 was that 7.0 used a 1.44MB boot image and 7.1
uses a 2.88MB boot image. This change was necessary because of the increased
size of the 2.4 kernel and also the increasing number of drivers needed in the
boot image for devices like SCSI, RAID, USB, etc.
The problem is that some BIOSes don't support 2.88MB boot images properly.
Booting off a floppy and then selecting CDROM is a workaround. This is a known
issue...it's unfortunate, but the number of people helped by the 2.88MB boot
image is larger than the number of people whose BIOSes have this problem.
