I have customized EMS settings in my SV 1000 so opted to update to 5.1 over 4.0 using Method 2. I am downloading using Safari on a MAC Pro. The 5.1 firmware fie downloads normally to my desktop and is a .exe file. The only other file I think I need is the Warning/Alert Graphics file. When I download it, it downloads as a text file and opens in my browser as all text. The file name has a DFG.TXT appended to the file. I deleted the .TXT leaving only the .DFG at the end of the file name and it then shows it as a .exe file so I thought I was ready to go.
The 5.1 file loaded normally and when it was finished, all is normal with the SV and I discovered I have Group Hardware 1. When I went to install the Warning/alert graphics file, it shows it has "0" KB in the file. I don't think this is a proper file.
Must I leave the .txt on the file to install? As a .txt file my computer shows it to be a 2KB file. None of the other download updates have ever downloaded as a .txt file and to open DFG files on the mac I have had to use a text editing program.
Must I even install the map graphics file at this time? The display looked fine to me with just 5.1 installed.
Attached is the file name that downloads:
