I tried to make a bootable CD-ROM with GRUB. It works only partial: The
menu-file is not found, and loading image/chainloading from the virtual
floppy fails with "Invalid
Yes. I can access both the real iso9660-filesystem and the virtual floppy
inside the booted GRUB.
Oops, I don't mean that. GRUB doesn't have iso9660-support. Yet :-) Thus,
I can access the virtual floppy when booted, and the iso-fs from a normal
PC.

I'm affraid that there is something wrong in the way how stage2 reads
floppy disks. Supposedly, a wrong sector was read.
I turned on "fstest", and verified with loading from a real floppy. The
output was exactly the same. So I think the right sectors are read, but
the read fails.

This works. And all directorylistings works too. I've added quite a lot of
debug-printf's, but have failed to find the problem. The bootsector

Did you use "d" option while installing the loader?
The option is not required. His CD-ROM can obviously boot fine.
I don't know anything about Easy CD Creator 3.0
chainloader=(fd0)/bootsect.dos, for example.
Try to insert a real floppy disk with the same image. 5% probability of
success.
This works. When booted from CD, the real floppy becomes fd1, so:
chainloader=(fd1)/bootsect.dos works.
But actually it seems that the filesystem code is to
Hmm... Can GRUB access your hard disks correctly? If not, try hard
disk emulation instead of floppy disk emulation. If my guess is
correct, that should work fine.
GRUB can access floppies just fine normally, but not via the emulation.
Maybe HD-emulation works, but I have very little
