The IGEL M330C has a BIOS that identifies itself as InsydeH20.
In the Linux dmesg output we find: IGEL Technology GmbH M330C/VX900, BIOS M330C V:3.0.13-09182013 09/18/2013.
Wait for the beep and then hit the DEL key on power-up in order get into the BIOS setup screens.
The 'Main' screen is a little short on detail. This is normally where can find the BIOS version number, SATA drive size, amount of RAM fitted.... With the M330C you're only offered two lines: System Time and System Date.
There's not a lot to set in the Boot options. You can enable/disable: Quick Boot, Quiet Boot and PXE Boot to LAN.
Under Legacy you can play about with the boot order between the local flash SATA drive and what ever is plugged into the USB ports.
