Hi irian and thank you for your reply.
I'm not able to boot from floppy cause the hardware doesn't have a floppy drive. So I don't know.
What I've found out is that it has something to do with the bootloader(?) and the BIOS. I'm using a special Single Board Computer (SBC) which has a Phoenix (or something like that) BIOS which is not compatible with the bootloader.
The situation now is that I've installed SME on another mainboard (VIA EDEN - mini-ITX) and it seems to be running as supposed. So now my problem is how do I get all applications to work (like MySQL, AntiVirus, AntiSpam, Apache and all other things for SME).
I'm completely new to Linux but like to know more about this OS (and SME in particular).
Regards
Brygger
