What is The Workstation 4?
Software Components
POS Application Update
An update to the POS application becomes available. The updated
application files are staged on the system server and the configuration file
is modified. Each CAL Client periodically checks with the CAL Server to
see if updates are available and recognizes the updated configuration file.
• If the CAL recognizes the update at boot time, it automatically
downloads the updated application and or support files, copies it over
the previous application and starts it.
• If the CAL recognizes the update while the workstation is operating, it
gives the user the choice of updating the application now or deferring
to a later time. If the operator chooses to complete the update now, the
updated files are retrieved, and copied over the application on the CF
card. Upon completion, the workstation is restarted.
Windows CE Operating System Update
During its routine check for updated applications on the system server, the
CAL Client also checks for an update to the Operating System (OS). An
updated OS becomes available and is staged on the system server.
• If an OS update is found, it is copied from the server to the CF card.
• The CAL invokes a cold boot of the WS4.
• The Boot Loader detects the OS image (a file called NK.BIN) on the
CF, transfers it to the DOC, and starts it. While this transfer is
underway, a black border appears around the MICROS logo and
progress bar as shown in Figure 1-11. The CAL deletes the updated
image from the CF card when it starts.
