Go down to middle of page and download v2.80 dated 18 jan '2005
When you install and open tftpd32, It will show a current directory path.you can change it to your desktop (if it already does'nt point to it). Because when you download OS file it should be in the same directory as tftp current directory.So save OS file at the same place as the root(current) directory of OS.Keep the TFTP exe file running as it needed to upgrade the OS.
Now login to pix from this PC and in config mode, give command
copy tftp flash
after this it will ask for address of tftp server: it should be the ip of this PC on which you have pix image file saved and tftp installed.
then it will ask for image file name: give pix614.bin
if it finds the file it will ask for confirmation: give yes
then it will erase old image and install new version.You should then be able to see the latest
version installed in sh ver command.
This is all we need to do.If there is any confusion or you need assistance feel free to contact me.
