Hmmmmm, it seems although specifications imply that the motherboard used 
in the Vintage barebone is the P4S800-MX it actually is a different one. 
I've tried to update the bios (to 1010c.awd) but this failed and 
produces the error message indicating the bios is not compatible in dos: 
"failed to find system bios hook".

The Asus website supplies a specific bios for the Vintage barebone. I'm 
beginning to think that might be the origin of my reboot problem ;-(

Thanks for your fast reply.
