BIOS Quick Reference
5.8 Standard Diagnostics Routines Setup Screen
Embedded systems may require automated burn-in testing in the development cycle. This facility is
provided directly in the system’s system BIOS through the Standard Diagnostics Routines Setup
Screen (Figure 5-7). To use the system, selectively enable or disable features to be tested, and then
enable the “Tests Begin on ESC?” option to cause the system test suite to be invoked. To repeat the
system test battery continuously, you should also enable the “Continuous Testing” option. When
continuous testing is started, the system will continue until an error is encountered.
Caution: The disk I/O diagnostics perform write operations on those drives; therefore, only spare drives
should be used which do not contain data that could be harmed by the test.
Caution: The keyboard test may fail when in fact the hardware is operating within reasonable limits. This is
because although the device may produce occasional errors, the BIOS retries operations when
failures occur during normal operation of the system.
5.9 Start System BIOS Debugger Setup Screen
The Embedded BIOS Integrated Debugger may be invoked from the Setup Screen main menu, as
well as a boot activity. Once invoked, the debugger will display the debugger prompt:
EB43DBG:
and await debugger commands. To resume back to the Setup Screen main menu, type the following
command, which instructs the debugger to “go”:
EB43DBG: G <ENTER>
