This chapter lists problems that may occur when you operate the JANUS 2050 and
provides possible solutions to those problems. It also provides different options for
resetting the JANUS 2050, and describes how to save data and update flash memory.

Troubleshooting the JANUS 2050

If you have problems operating the JANUS 2050, review the following tables
listing problems and their possible solutions. Problems are grouped into
common areas for easier reference. For example, problems you might see while
running an IRL program are grouped in one table.

Powering Up or Booting the JANUS 2050

This table lists problems that may occur when turning the JANUS 2050 on or
off, or when booting the JANUS 2050.
Problem
When you turn on or cold boot the
reader, the Boot Loader menu appears.
The menu may not list all the Boot
Loader commands, and the screen may
include a status message. For example,
the partial Boot Loader menu may look
like this:
Boot Loader
Dump
Load
Storage
Off
Bad BIOS Checksum
Please Load BIOS
20X0A.003

Solution
The bootstrap checks the system flash when doing a resume or
cold boot. If the system flash is corrupt or there are bad
checksum error messages, it brings up the Boot Loader menu.
Read the status messages at the bottom of the menu.
If you see "Bad BIOS Checksum" or a message that indicates the
system flash is corrupt, you could save the contents of
conventional memory using the Dump menu selection, but you
must reload the system flash.
If the system flash memory is corrupt, you can dump memory
and reload the system flash. For more information about
reloading flash memory, see "Saving Data and Loading Flash
Memory" later in this chapter.
