This is all we've got so far - we are missing the util to take a normal kernel image and do whatever it is that needs to be done to make the T1500 to netboot it :-( The file was too large for my web host, so it has been split (with 'split'), into files consistng of a group of letters `aa', `ab', and so on, such that concatenating the output files in sorted order by file name produces the original input file.
