Syslinux - Nov 2003 - RE : SYSLINUX 2.07-pre6 and memdisk decompression problems

Hi,
I tested this version and it works all right ! Thanks a lot for the quick fix.
Do you still want to see the output in order to check everything is OK, or you
don't need it ?

Now that's bizarre...

I didn't really change anything that should have solved the problem... 
all I did was add debugging code!  I don't need the output if it works 
now, but boy am I confused.

I'll send you a separate memdisk binary in a separate email... do you 
think you could try it out for me?
