Okay, I have an image for you now. I hope your friend knows how to set up a NFS and DHCP server. 1.) download a few files, namely: - the netconsole client - a kernel with netconsole built-in - a version of CoLo with netconsole support (just in case the CoLo on your Qube is very old - shouldn't be the case though) wget http://www.cyrius.com/debian/cobalt/colo/ncon.c wget http://www.cyrius.com/debian/cobalt/colo/vmlinux-2.6.16-1-r5k-cobalt wget http://www.cyrius.com/debian/cobalt/colo/vmlinux.gz 2.) Compile and start the client: $ gcc -o ncon ncon.c $ ./ncon 192.168.1.69 | Connect: 6666 --> 192.168.1.69:6665 | [[[ press CTRL-D to exit ]]] 3.) Boot Boot the Qube, and choose the last point in the menu ("Network shell"). If there's no such point, setup a proper NFS server for Cobalt according to http://www.cyrius.com/debian/cobalt/) and boot via the network (left and right cursor key pressed at the same time). You should then see output on the netconsole client, like this: | netcon: 6665 --> 192.168.1.1:6666 | script exited <1> | > Okay, there's the prompt - now load the kernel via NFS: > nfs {dhcp-next-server} {dhcp-root-path} vmlinux-2.6.16-1-r5k-cobalt nfs: mounted "/nfsroot" nfs: lookup "vmlinux-2.6.16-1-r5k-cobalt" nfs: mode <0100644> 2553KB loaded (143KB/sec) 0027e524 2614564t nfs: unmounted "/nfsroot" > And start it, telling it to use netconsole: > execute root=/dev/hda2 [EMAIL PROTECTED]/eth0,[EMAIL PROTECTED]/ [wait a bit, don't worry. after about 20 seconds you should get output] Linux version 2.6.16-1-r5k-cobalt (Debian 2.6.16-2) ([EMAIL PROTECTED]) (gcc version 4.0.3 20060212 (prerelease) (Debian 4.0.2-9)) #2 Thu Mar 23 23:32:22 UTC 2006 CPU revision is: 000028a0 FPU revision is: 000028a0 Cobalt board ID: 5 Determined physical RAM map: memory: 08000000 @ 00000000 (usable) ... 4.)
