8.1 General Information
The ITX-F-3800 includes a UEFI BIOS from Insyde stored in Flash ROM. Access setup
information through the BIOS setup utility to modify basic system configuration. The
configuration is stored in CMOS RAM (it is retained during power off). When power is
applied to the system, the ITX-F-3800 communicates with peripheral devices and
checks hardware resources against the configuration information stored in the CMOS
memory. If during startup an error is detected or the CMOS parameters need to be
initially defined, the diagnostic program prompts the user to enter the SETUP program.
Some errors are significant enough to cause the startup to fail.
