cristian: well, here are some screenshots from me...

crist at mobile60:~$ file /tftpboot/potato_root.bin 
/tftpboot/potato_root.bin: gzip compressed data, deflated, original
filename, `potato_root', last modified: Wed Nov  7 16:47:49 2001, os:
Unix
crist at mobile60:~$ file /tftpboot/potato_root     
/tftpboot/potato_root: Linux rev 1.0 ext2 filesystem data (mounted or
unclean)

let's see now if we can mount this root image...

crist at mobile60:~$ mount | grep loop
/tftpboot/potato_root on /mnt type ext2 (rw,loop=/dev/loop0)

well, it's mounted all right; let's have a look at init:

crist at mobile60:~$ file /mnt/sbin/init 
/mnt/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1,
dynamically linked (uses shared libs), stripped

so, from my point of view everything looks quite o.k. still, the kernel
does not boot ;-(

thanks again and
bye now!
