This is more a note then a question about the maprom function on the ACA1234 maprom.
I received my ACA1234 yesterday and loaded kickstart 3.2 from my harddisk.
After that my screen showed a red color which mean rom error.
Luckly i could whipe the rom with the jumper on the ACA1234 which erase the eeprom.
After this i installed kickstart 3.2 from a floppydisk and this worked very good.
I now have kickstart 3.2 in the flash rom from the ACA1234!
So my advise is when you want to load a kickstart in the flashrom do it from floppydisk.
