[bug #14758] CD boot only gives Error 25: Disk read error

[G Fraser]

Follow-up Comment #6, bug #14758 (project grub):

Eltorito-based Grub CD tests on Gentoo showed all current Grub versions, from
0.96-r1 through 0.97-r2, give error 25 when selecting from the distros
displayed on the Gentoo splash screen.

Similar tests on Slax 5.1.4 gave error 25 with Grub version 0.97, a module
converted from Slackware grub-0.97-i486-2.tgz.

However, Kanotix 'Easter Edition', which uses grub-0.97.7.1 (Debian) produced
Grub CDs which worked perfectly.

To see if the Gentoo errors were RAM involved I recompiled without himem,
effectively limiting RAM to 800+ MB. Re-emerged grub, but nothing helped.

Finally I copied both stage2_eltorito files which worked to Gentoo, and made
Grub CDs which worked perfectly. 

The 'good' files were: 
Slax grub module version 0.95
Kanotix  grub version 0.97.7.1

NB! In case its relevant - at the same time as adding RAM, I swapped my 160GB
2nd hard drive with a 320GB replacement.
