0.4.6a does not boot from CD

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Make a grub4dos bootable ISO with grldr as bootfile


What is the expected output? What do you see instead?
boots to console (no menu) - if do ls / command then get rubbish characters.
0.4.5c works fine.

ISO made from a working USB Flash drive using RMPrepUSB - Ctrl+M which uses 
mkisofs to make the ISO. 
Then test ISO using RMPrepUSB - Ctrl+F11  (or VBox).


What version of the product are you using? On what operating system?
0.4.6a  1-17-2014 release version

Please provide any additional information below.

Iso file you generate tool, not well supported Joliet specification. He put the 
address 0x1f Joliet file directory wrote 0x1e (in 0x909e and 0x90a5 Office). 
Please observe. 
0.4.5c version does not support Joliet format, so no problems.

If I used isolevel 3 then no problem.
If I use isolevel 4 then I get the problem.

If you have a problem, do not use the-J

isolevel 3 -J works
isolevel 4 -J gives the problem

So is the problem that grub4dos does not support isolevel 4?

Do not know, never use isolevel parameters.

Level 4 is for ISO 9660:1988 spec.

If use 0.4.5c then can see the filesystem and can use kernel and initrd 
commands.

0.4.5c version does not support Joliet format, so no problems.
Is a software tool enables Joliet extensions directory pointing to the base 
directory.

so will there be a fix for 0.4.6a?

At the moment it cannot be used to boot ISOs if they are in Joliet ISO9660:1998 
format
e.g.

map /myiso.iso (0xff)
map --hook
kernel /vmlinuz
initrd /initrd

does not work because it cannot access the filesystem.
If not, can we force 0.4.6a to not use Joliet so it will work like 0.4.5c?
