Ok, but how can I change / adjust the clock rate? The software does not
support this feature.
PonyProg plus the SI-Programmer (serial adapter) has no options for clock rate
and in CodeVision
I haven't found one, too. (used with STK 200+/300-ICSP-Dongle on parallel
port)

I'd put them in designing the schematics...
Reset is well down to ground - I've checked this

Erhhhhh - I don't use the STK500 and I don't want to use it if it's possible
(SMDs don't
fit in DIL-sockets very well).
