[syslinux] booting clonezilla *.iso via PXE fails

[Helmut Hullen]

Hallo,

I'm just trying to boot a Clonezilla *.iso (live-20100521-lucid) via  
PXE;

   Label clonezilla
   kernel memdisk
   append iso raw
   initrd iso/clonezilla.iso

The first step is ok - I see the boot menu of the *.iso.

When I choose "Clonezilla live" the system fails with

  Isolinux: Disk error 02, AX = 4224, drive E0

when I choose "freedos" it fails with

  Loading memdisk
  Loading /live/freedos.img...isolinux: Disk error 02, AX = 42D8, drive E0

  Boot failed: press a key to retry

------------------------------

The second run shows that somewhat tries to access "freedos.img" via  
absolute path - no good idea.

Is that an uncorrectable error in the clonezilla configuration, or is  
there some trick with the *.iso image?

-------------------------------

The other way is unpacking the *.iso and extracting the contents  
somewhere in the "/tftpboot" path - that works. But that's more work  
than simply booting the *.iso. And I have many *.iso images which allow  
this simple way.

--------------------------------

"append iso" and "append iso raw" make no difference with this *.iso.

--------------------------------

The predecessor (Ubuntu clonezilla-live-20100330-karmic.iso, 123904  
kByte) fails in another way: after some traffic it tells

  Boot failed
  ...
  Unable to find a medium containing a live file system


Viele Gruesse!
