SYSTEM STARTUP FEATURES
At power up and any media insertion the MDVR searches the hard
drive first, then the SD card(s), if present for a folder named
“SYSTEM”. The first SYSTEM folder found will be used as the
startup folder and its contents processed. The following features
are available via the SYSTEM folder.
INSTALLING SYSTEM UPGRADES
Software / Firmware updates are distributed in files with a *.dvr
extension. Mount either the removable hard drive or optional SD
card to a PC. Find or create at the root of that media a SYSTEM
folder. Copy the *.dvr file into the SYSTEM folder. Remove this
media from the PC and install it into the MDVR and then power
cycle the MDVR. The MDVR will automatically install the *.dvr file.
Placing multiple *.dvr files in a SYSTEM folder will have
unpredictable results and is not advised. The system will not re-
install the same upgrade so there is not a problem to leave the
*.dvr file on the media until the next upgrade opportunity.
