PCA-6782 User Manual
The BIOS Flash utility allows customers to update the
flash ROM BIOS version, or use it to back up current BIOS
by copying it from the flash chip to a file on customers'
disk. The BIOS Flash utility also provides a command line
version and API for fast implementation into customized
applications.
The embedded application is the most important property
of a system integrator. It contains valuable intellectual
property, design knowledge and innovation, but it is easily
copied! Embedded Security ID utility provides reliable
security functions for customers to secure their application
data within embedded BIOS.
Monitoring is a utility for customer to monitor the system
health, like voltage, CPU and system temperature and fan
speed. These items are important to a device; if the critical
errors happen and are not solved immediately, permanent
damage may be caused.
Flash Lock is a mechanism to bind the Board and CF card
(SQFlash) together. User can "Lock" SQFlash via Flash
Lock function and "Unlock" by BIOS while booting. A locked
SQFlash cannot be read by any card reader or boot from
other platforms without a BIOS with an "Unlock" feature.
The eSOS is a small OS stored in BIOS ROM. It will boot up
in case of main OS crash. It will diagnose the hardware sta-
tus, and then send an e-mail to administrator. The eSOS also
provide Remote Connection: Telnet server and FTP server
for administrator to rescue the system. Note: This function
requires BIOS customization.
