Agent Greeting Application Upgrades
VPS(NTVQ09AB) Agent Greeting Application
Upgrade Details:
The VPS Agent Greeting Card (NTVQ09AB) stores up to
two versions of loadware in flash. This mechanism
ensures that if there is a power outage or other failure
during upgrade the card still has a valid load in flash. A
small boot code segment is located in the BIOS flash
area, which chooses the “newest” load from one of two
flash banks to uncompress into DRAM. Once the
uncompress has completed, execution switches to the
code entry point in DRAM. The card must be
rebooted/reset for the new loadware to execute.
Media Card (NTVQ09BA) Agent Greeting
Application Upgrade Details:
The Media Card (NTVQ09BA) Application loadware is
stored as the file C:/exec on the compact flash drive. To
upgrade the card, the contents of this file, must be
overwritten with the new target load. The card must be
rebooted/reset for the new loadware to execute.
_________________________________________
It is recommended that a backup of the PC Card
flash Memory be carried out before upgrading
the loadware. See Installation guide for backup
and restore procedure.
