I have updated 4080 BIOS that I recieved several months ago via email from Sager (which makes it so that infernal boot-beep can be disabled, amoung other things). The files on the ISO they sent me are dated 2004-07-08. I think the version it displays is 1.0.A1 or something. If you email Sager they will probably send you the current one, if i remember right they ask for the laptop's serial number to verify.
Edit: Looked at Eurocom's site, Thats the same version number mine displays, and these are Clevo D400V systems, so i imagine that will work for you.
