10 Additional BIOS Features

The conga-TCA uses a congatec/AMI AptioEFI that is stored in an onboard Flash Rom chip and can be updated using the congatec System

Utility, which is available in a DOS based command line, Win32 command line, Win32 GUI, and Linux version.

The BIOS displays a message during POST and on the main setup screen identifying the BIOS project name and a revision code. The initial

production BIOS is identied as TCEDR1xx where TCED is the congatec internal project name, R is the identier for a BIOS ROM le, 1 is the

so called feature number and xx is the major and minor revision number.

The size of the conga-TCA BIOS binary is approximately 4MB.
