Re: GRUB2 fails when booting from CD

[Andreas Born <futur.andy@googlemail.com>]

Ok, here you go. I created the same iso image I referred to earlier in 
this thread with grub 1.98 and cdfailinf/cdfailwa patch applied.

cdfailinf (broken machine): 0 0 0
cdfailinf (working machine): 0 0 9f

cdfailwa brings up the menu on the broken machine and on another working 
machine, where I tested it too.

Hope that helps.

Regards,
Andreas
