10.0 Software
10.1 FLASH Update Capability
The software in the AV28 media center is stored in FLASH. During boot, the software is decom-
pressed from the FLASH to the DRAM, where it is executed. U1 can update the contents of the
FLASH, so the software is field upgrade-able. Additionally, the console can update the FLASH
where the DSP stores its code in the LS28/35 bass module using the speaker cable.
10.2 FLASH Update Procedure
Note: A software update disc can be obtained by calling Bose service. If you have a software
update disc, check the service intranet site or call Bose service to make sure you have the latest
version.
10.3 Software Version
To find out which version of software is loaded in a console, first press the [ALL OFF] button on the
keypad. Next, press and hold the [STORE] key and press the [ENTER] key one time. The soft-
ware version is displayed on the VFD in the following format: SV C:(dateCode):(version)-(build) –
for example, SV C:092501:1.0-0125 would indicate Version 1.0 code made from build #125 on
September 25, 2001.
10.4 User Settings Stored in FLASH
Certain user settings (tuner presets, OSD settings like preference for Film-EQ in a particular
source) and tuner calibration coefficients are stored in a protected area of FLASH. These are not
overwritten when the software is updated. There are two important consequences:
• Sending an FU [Flash Update] command via ETAP will erase the user settings (but not the
tuner calibration).
• After setting any preferences (house code, tuner presets, OSD settings), you must cycle the
power on and off with the remote and wait a few seconds before unplugging the unit. When the unit
is powered off by the remote, the user preferences set in that session are stored in FLASH.
