The IGEL 2110 has a standard PC Phoenix Award BIOS - hit the DEL key repeatedly on power-up in order get into the BIOS setup screens. It will boot from flash, IDE drive, CDROM or USB.
Booting Puppy Linux from a USB connected CDROM drive worked well. The on-board Compact Flash card is visible (sda) and contains a single Linux partition (sda1), however I'm not sure exactly what filing system is in use as Puppy would not mount it. (ie It is definitely not ext2 or ext3).
Any comments? email me. Last update September 2009
