BIOS Messages

Power-up self-tests are the system tests and component initialization processes performed by the AT-compatible ROM
BIOS in the TravelMate 2000 Computer.  The central hardware is tested and initialized first.  Proper functioning of the
central hardware is required before further system tests can be run.  In general, a failure in a test of the system board
or its components will result in the sounding of a beep, and a halted system.  A failure in add-on boards or memory is
reported on the screen.

There are two types of messages displayed if the Travelmate 2000 fails one of the power-up tests:

‰

Error messages indicating a failure in the hardware, software, or firmware

‰

Informational messages about the power-up and booting processes

Power-up messages are fisted below, with possible causes and solutions.

Messages that do not appear in this list indicate hardware faults that can be solved only by internal checks.  Contact
your authorized Texas Instruments dealer or Texas Instruments Service Center.
