That worked, but I don't seem to be able to mount it after uncompressing it:

# mount -o loop bigDos.img /tmp/1
mount: you must specify the filesystem type

# mount -t vfat -o lopp bigDos.img /tmp/1
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
        missing codepage or other error
        In some cases useful info is found in syslog - try
        dmesg | tail  or so
# dmesg
FAT: invalid media value (0x00)
VFS: Can't find a valid FAT filesystem on dev loop0.


How can I edit the image? I need to do so in order to get networking up 
and running

Hmm looks like they have a nice script there, will give that a try.


Thanks
