EEPROM on A1200?

[_yak_]

Uhm, it's probably a dumb question. I don't know where is the ROM mapped in the memory but is it possible to use a bigger EEPROM chip? :roll:

[_yak_]

I don't know how is the ROM build up but I presume it is some kind of a list of modules, right? And since the ROM is always at the same address, the modules probably contain direct pointers to successors/predecessors. If all this is true, it should be easy to write a program to divide the ROM into two 512KB parts. It would be cool to have whole another 512KB for additional modules . Does someone there actualy know how the ROM modules are linked together?

[_yak_]

Basically exec searches through the memory areas it knows could contain a ROM for the RTC_MATCHWORD value ($4afc), if it finds it and the next longword is the address of the $4afc then it knows it's found a resident and then adds it to the resident list ( only if a greater version hasn't already been found etc.)

So, the conclusion is we CAN use 2x512KB EEPROM chips without problems?

@ Nickman

Was there also such a tread here, on Amiga.org? I think most of the people here are "classics oriented" :-)
