Hi Brusque,

I found exactly the same problem (programmer + PICALL software).

I believe that it's a bug in Microchip's assembly-language `.inc' file for the
18F series.

The include files are set up to construct a configuration byte value by
`AND'-ing a series of options. This means that unimplemented bits (and bytes)
end up set to `1'. However they read as `0' when the software goes to verify
them, resulting in a discrepancy [ if you remove all unimplemented bits then
FEFF and 2600 are the same thing ].

I manually edited the configuration words in PICALLW after the loading the
program, to mask out the unimplemented bits, which works.

By the way, GPASM (Linux, etc) has the same problem.

Cheers
Scott
