Can I use a CD32 Kickstart in another Amiga?

[Doobrey]

I`ve seen it done on an A1200.Not in the flesh, but on a website, they did built a rom switcher for it.
Like the hairy pillock I am, I didn`t bookmark it :pissed:

Then again, you say it`s one 16bit rom ?? Could have sworn CD32s had 2 roms just as the other 32bit miggies did, at least the schematics I got here show it that way.

As for using it on an A500 or 600, If it really is 16 bit rom, maybe..
Dunno whether CBM built that rom on the assumption that it would at least have an 020 to run on.

Maybe the best way is to fire up UAE set to 68000 cpu and 1Mb chip with ECS and test an image of that rom ?

DOH!
 Just looked at a piccy on amiga-hardware.com...
 It is a single 1Mb rom image. I take it that was CBM and their famous cost cutting again..

 Erm.. the CD-ROM driver in the CD32 won`t work for IDE or SCSI drives.

if someone ever creates a 3.5 ROM or 3.9 ROM......please take note of this.maybe make it a 5Mb ROM?  or at least 2mb to fit the stuff (I hate Kickflash crap!)  

2MB is the limit for a replacement rom (ie. not kicked to memory.
 Actually, it`s more like 2.5MB, but it`s in 4 different chunks ,3x512Kb + 1x1024Kb, but some Cyberstorm (maybe Blizzard PPC too??) take over one of the 512k areas for themselves.

 Why CBM couldn`t lay out these memory areas into one big linear space is a mystery to me..

Anyway, just to brag.. my A1200 flashrom gizmo has been working fine now for the last week. It`s only 1Mb, but it single boots straight into 3.9 with no resets.:-D
 Still need to get a proper PCB made, it`s currently a mass of stripboard,SMT board about 150 wires and a sprinkling of glue logic..

Just tried it on UAE, and it constantly reboots when it`s set to a bog standard 68000. I can only get it to a WB screen by setting it to 020. The latest version of WinUAE even popped up a message saying the rom needs an 020 and wouldn`t even attempt to run.

Nope, it is in the CD32 rom.
It`s a single 1Mb Rom, the "extended" rom is in the lower 512k, and the normal rom in the top 512k.
 The only reason you find it split into 2 parts is so UAE can handle it the way it does for the CDTV roms.

 What I didn`t expect is the normal rom has all the guff that the A1200 uses, but is useless on the CD32.. scsi.device and the PCMCIA resources.
