Upgrading the BIOS
Should it be required, this section describes how the BIOS is upgraded on
Windows Embedded CE 6.0 or POSReady 2009 configurations.
Windows Embedded CE 6.0
For Windows Embedded CE 6.0, a BIOS upgrade is handled by the CAL
through a Platform Update. Executing the Platform Update on the server places
the BIOS image and support files in the appropriate CAL server folders, which
in turn distributes the files to the CF card of each workstation.
A BIOS update consists of the three files: QUNTICO.BIN, QUNTICO.LOG,
and QCHKSUM.LOG. After the CAL places these files on the root of the CF
card, it restarts the workstation.
When the unit restarts, Platform Update detects the QUNTICO.BIN file,
performs a file size check, then generates a checksum against the binary file.
The generated checksum is compared to the value stored in the
QCHKSUM.LOG file. If the checksum match, the BIOS update proceeds and
a message appears that a BIOS update in progress.
• If the checksum values do not match, the error messages:
‘BIOS File Chksum Failure!’
‘BIOS Not Updated’
If this error occurs, Platform Update deletes the QUNTICO.BIN file and
creates a file called QBIOS_ERR.LOG on the CF Card to indicate the
BIOS binary file is corrupt.
After the BIOS update is complete, the workstation restarts. To prevent
Platform Update flashing the BIOS a second time before the CAL removes the
binary file, it created a file called BFLASH.LOG.
BFLASH.LOG is a text file that contains the current date in the format
mm/dd/yyyy. Platform Update compares the date of the QUNTICO.BIN file
with the date stored in the BFLASH.LOG file. If the dates match, the BIOS
skips the update and continues with the boot process.
