Presumably it'st ISOLINUX that is using the BIOS to find and read 'blocks'
off the media, or its it using the BIOS to read 'files' off the media?

If its reading 'blocks', then something has do do a CHS translation
for where the file is located.

If its reading the 'file', I guess the directory and file must be within
the CHS restriction too.

To validate this theory...
Is there anyway of finding out what ISOLINUX has read as the config file?

OK, but 3.10 is what Fedora has used in their current snapshot.

They are completely different systems, CD-ROMs, and BIOS.
But their BIOSs could have similar issues.
