This should read 256 kilobits; that is exactly 32kB.

If you didn't do anything wrong while burning the EPROM, there is no
blank space left.

Follow the trouble-shooting instructions in the "etherboot" or
"netboot" documentation to track down the problem. Also, it really
helps a lot, if you check the output from the "romscan" program that
ships with "etherboot". "Netboot" now comes with a similar tool, but I
have not had enough time yet to look into it --- in his e-mail, Gero
suggested that it is probably very similar to "romscan".
