The eSeSIX WLGX01 has a standard PC 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 or CDROM. There is no USB boot support.
Firmware
Boots something called j-stream(?) off the Compact Flash card - based on a 2.4 Linux kernel. Having booted
(and not found any servers?) the system powers off.
