1/ Set up your DHCP server scope to respond to bootp requests. On Windows this is a tick box option.
2/ Set up the Option tags 66 and 67. 66 it the IP address of the TFTP server and 67 is the file name.
3/ Download TFTP32 and run this with the binary file in the TFTP directory
4/ Boot the unit with the “Q” key, this starts a bootp boot. In the Rapport, CE downloads on this site there are files to remotely start this process of rather than having to press the key.
So that’s how I have done it, and I have converted 1000’s remotely this way. One other issue to be aware of, if you find the 3235 does not convert correctly or will not convert there are some units with bad BIOS chips (NOR). Open the case, remote the daughter board and look at the NOR – the AMTEL ones are the ones with issues. Only option is to buy a replacement,
