Powering Up or Booting the Reader (continued)
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:
BOOT LOADER
Dump
Load
Storage
Off
Bad BIOS Checksum
Please Load BIOS

When the reader finishes booting, an icon
remains on at the top of its display.

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, save the contents of conventional
memory and reload the system flash. For help, see
"Dumping the Reader's 640K Conventional Memory" and
"Loading Flash Memory" in Chapter 9.
• If you see "Bad Saved State," the reader may have been in
Storage mode. Press
exit Storage mode, press
You may also see the "Bad Saved State" message if you press
to suspend the reader while it is booting. Press
reboot the reader. You may be able to save the contents of
the physical RAM drive. For help, see "Saving the Contents
of the RAM Drive" later in this chapter.
Caution
When the reader performs a cold boot, all files on the
physical RAM drive are destroyed.
Conseil
Lorsque le lecteur effectue un amorçage à froid, tous les
fichiers présents sur le lecteur de la mémoire RAM
physique sont supprimés.
Contact your Intermec service representative.
When the reader boots, the CPU starts all power cycles and
turns all icons (except for Battery) on and off. The icons turn off
very quickly as the reader passes a series of bootstrap code
checks. Any icon that remains on indicates where the bootstrap
code failed.
