Are 3.x Kicstart Roms the same for A1200 and A4000?

Hi All,

Are the Kictstart ROM chips from an AGA amiga interchangable? For example could I use the 2 kickstart 3.1 rom chips from my A1200 in an A4000? I'm pretty certain that the chips would fit but are there any differences in the kicstart software itself to handle slight differences in the hardware?  

A1200 rom includes specific drivers for pcmcia and ide and A4000 rom includes drivers for a4000 ide. These are not interchangable. Use Blizzkick or buy new roms :-)

It's possible that an a1200 kickstart would work in an a4000.

You would lose IDE support. A1200 roms may try to initialize ide at wrong address & pcmcia so perhaps it's not a good idea. A4000 in A4000T on the other hand would probably work but you would lose motherboard scsi support.
