Ya know David, sometimes you just crack me up...
Programmer, easy change?!?!?!
Somehow, I just don't see most people seeing;
1. Desolder the surface mount eprom.
2. Put in programmer and dig through hex code for the serial number.
3. Change the serial number.
4. Resolder the surface mount eprom.
5. Test the change
as all that easy...
NOTE: "Some" boards may have the chip in a socket...
Sorry David, I just couldn't help myself... It was just too funny to pass up...
And for the record, it has been bugging me too, but I looked and didn't see anything obvious anywhere. The 4400 BIOS has a place to do it, but not the 4200/4500/15000. We must have dreamed it... Let me know if you remember or find it...
