You can either use xmodem via lan/serial port from the port activity screen (not sure if putty supports this. I copied the hyper terminal files from a win xp machine and run that under win7)

Or put the svmi in backup/restore mode and ftp the file up.

You will then need to convert it to a pmt file with the buildpmt utility from a dos prompt on the svmi (or download that file and run it from your pc)
