[syslinux] memdisk issue with gpxelinux.0

[Pierre]

Helle,

I'm facing a strange issue with memdisk

The context :

syslinux 3.75
gpxelinux.0

the gpxe stript called from a menu executed through menu.c32 :

#!gpxe
kernel /modules/memdisk initrd=/freedos
initrd /freedos

The output before the freeze :

/boot.gpxe. ok
/modules/memdisk. ok
/freedos...... ok

Loading boot sector... FR<p>Dbooting...

After that the server is frozen.

The floppy image is correct and its size is 1440 K (1474560 bytes) not
1455 K as indicated above

I have the same results on 2 servers whith different architectures

Can someone tell me about the exceedings 15696 bytes (and what mistake
I have made) ?

Thank you

Regards

Pierre
