Powering Up or Booting the Reader (continued)<br />

Problem Solution<br />

When you turn on or cold boot the<br />

reader, the Boot Loader menu appears.<br />

The menu may not list all the Boot<br />

Loader commands, and the screen may<br />

include a status message. For example:<br />

BOOT LOADER<br />

Dump<br />

Load<br />

Storage<br />

Off<br />

Bad BIOS Checksum<br />

Please Load BIOS<br />

<strong>2020</strong>U.191<br />

When the reader finishes booting, an icon<br />

remains on at the top of its display.<br />

The bootstrap checks the system flash when doing a resume or<br />

cold boot. If the system flash is corrupt or there are bad<br />

checksum error messages, it brings up the Boot Loader menu.<br />

Read the status messages at the bottom of the menu:<br />

• If you see “Bad BIOS Checksum” or a message that indicates<br />

the system flash is corrupt, save the contents of conventional<br />

memory and reload the system flash. For help, see<br />

“Dumping the Reader’s 640K Conventional Memory” and<br />

“Loading Flash Memory” in Chapter 9.<br />

• If you see “Bad Saved State,” the reader may have been in<br />

Storage mode. Press to reboot. If you are prompted to<br />

exit Storage mode, press again.<br />

You may also see the “Bad Saved State” message if you press<br />

to suspend the reader while it is booting. Press to<br />

reboot the reader. You may be able to save the contents of<br />

the physical RAM drive. For help, see “Saving the Contents<br />

of the RAM Drive” later in this chapter.<br />

Caution<br />

When the reader performs a cold boot, all files on the<br />

physical RAM drive are destroyed.<br />

Conseil<br />

Lorsque le lecteur effectue un amorçage à froid, tous les<br />

fichiers présents sur le lecteur de la mémoire RAM<br />

physique sont supprimés.<br />

Contact your <strong>Intermec</strong> service representative.<br />

When the reader boots, the CPU starts all power cycles and<br />

turns all icons (except for Battery) on and off. The icons turn off<br />

very quickly as the reader passes a series of bootstrap code<br />

checks. Any icon that remains on indicates where the bootstrap<br />

code failed.<br />
