The integrated COMExpress® module (COMe-bSL6) integrated in the KBox C-102 is equipped with Aptio® V, which is
located in an onboard SPI serial flash memory. The uEFI (Unified Extensible Firmware Interface)/BIOS is set at the
factory, corresponding to the system's standard hardware configuration and for normal operating conditions.
Therefore there is no need to set or change the BIOS environment to operate your system.
A detailed BIOS description can be found in the manual of the installed COMExpress®
module. You can download the corresponding manual from our web site www.kontron.com
by selecting the product name.
The Kontron uEFI BIOS features a built-in and enhanced version of the uEFI Shell. For a detailed description of the
available standard shell scripting refer to the EFI Shell User's Guide. For a detailed description of the available
standard shell commands, refer to the EFI Shell Command Manual. Both documents can be downloaded from the EFI
and Framework Open Source Community homepage (http://sourceforge.net/projects/efi-shell/files/documents/).
Please note that not all shell commands described in the EFI Shell Command Manual are
provided by the Kontron uEFI BIOS.
