RT314 guide...
It's not telling you to convert the file to a ras, it's telling you to send the firmware code via FTP to the router and have the router save the file as "ras".
i.e.
If the firmware file is named:
320ca1b3.bin
Then this is how you would upgrade (
Bold = things you type):
Go to the directory where you unzipped the firmware files...(C:\rt314\software\ in the example below:
<<
C:\rt314\software>ftp 192.168.0.1
Connected to 192.168.0.1.
220 RT314 FTP version 1.0 ready at Sat Jan 1 00:01:45 2000
User (192.168.0.1: (none)):root
331 Enter PASS command
Password:1234 <--Substitute your real password here
230 Logged in
ftp>bin
200 Type I OK
ftp>put 320ca1b3.bin ras <-- This will store the 320ca1b3.bin file to the router as "ras"
200 Port command okay
150 Opening data connection for STOR ras
226 File received OK
ftp: 780052 bytes sent in 3.35Seconds 232.85Kbytes/sec.
ftp> bye
C:\rt314\software> >>
After typing bye...The router will flash the "test" LED a few times and reset itself...
If you have an older firmware then 2.5, you'll also have to use the FTP and send an image (.ROM file) of the settings to the router. The ROM file is included in the fireware zip file.
Good Luck!
