found this link helpful for the tftp upgrade: http://www.users.qwest.net/~rlutton/ADSL/CBOS_Upgrade.html I was able to do a tftp upgrade from linux to a cisco 675 a couple versions back. With the last 2 cbos updates I keep getting errors about corrupted file (eventhough I'd downloading from the net as a binary; tried lynx, wget, curl, etc... still says corrupted file). I called my ISP (Visi) who of course said they only support windows and mac for doing the cbos upgrade. :P After the old 'college try' I ended up hauling my windows box to the basement (mouse, keyboard and all that jaz) just to do a frickin cbos update via hyperterm. It took close to 10 minutes to send the file up there, and of course, no errors. if anyone has input on the tftp solution, please speak up! Michael D.
