RE: Opteron / Tyan motherboard fault on boot.

I guess that you have some problem with your Etherboot configuration.

Also please let us know your compile environment.

I will send you my pre-built image and etc..via our FTP server.

The 'Q' option is generic in etherboot and it does not do anything sensible
under LinuxBIOS.  So you are probably triggering a triple fault again.
It does look like the code you have does not know how to reboot properly
but that is a minor issue.

Unless you have an ELF header at the start of your disk that is likely
the culprit.

The simple path is to get etherboot working with an image created by
mkelfImage.

You have a cluster node with a floppy drive?
