Is it possible to run kickstart out of fast ram? I have an Amiga 500 with kickstart 1.2 and I am interested to experiment with copying Kickstart 1.3 to ram, resetting pointers and rebooting the computer. Could anyone enlighten me as to how I go about reading a kickstart disk? Some will probably say that I should just go out and get hold of the 1.3 rom but I want to try this out if possible. Please direct your replies to me via email. Jonathan Thyer thyerj@uncg.bitnet thyerj@steffi.acc.uncg.edu

The LUCAS/FRANCES pd accellerator for the Amiga 1000 will also remap the ROM image into fast ram. It does so by providing an program to move the ROM data, set a flip-flip to translate the addresses in the memory addressing hardware, and off you go! As far as I know, Dave's SetCPU program only works on systems with a MMU. Wildstar
