Script Function:
Query local device WMI info and perform a SQL lookup to check for firmware updates. The SQL database contains
device models, current firmware version, and the path to the update package. This script looks for the firmware
version based on the device model, and then copies the installer to the host drive. The script then performs a
silent install of the firmware update all the while preventing an accidental shutdown. This script has a verbose
log which gets copied to a network location if there's a problem. If it's successful the log writes a single
line to a master log in the same network location reporting it's success. Once the update is complete, the
installer file is deleted, as well as the local log file.
Version Notes:
1.0.03 - Adjusted final write to local log so that the $FirmwareDBResult is written in the log.
1.0.02 - Added processwait() to script to prevent premature script completion
1.0.01 - Added values to BIOSString dump in addition to names
1.0.00 - Initial complete version
