Software for building custom Kickstart

[motorollin]

In particular check my post dated 2006/6/16 11:04. It details exactly how to do it.

Is the A4000s Kickstart ROM 1MB in size?

So does the A1200, but it won't use it. The extra 512K will be ignored.

Yes you just select the module in the right pane of Remus and add it to the ROM image, just the same as a component of a ROM image.

The only way to get more than 512KB in your Kickstart ROM is if you use exec from the CD32 ROM (which does have a 1MB ROM). As for the hanging problem, what does your ROM image contain, and what did you try to run? Did you follow my instructions exactly, including the operations in WinHex and the swap byte operation before burning the chips?

Interesting... Who knows if AmigaOS ROM Update contains an updated version of the CD32 Exec too?

I don't know. Just open the ROMUpdate in Remus and it will show all the different versions of exec and which architecture they are designed for. If there's not a CD32 specific version and you really must have a 1MB ROM, then you will have to use the 3.1 version of CD32 exec.

Well I had actually missed the "shell", which is a required component :-) As for the operations, I do them under DOS with the utilities of my burner.

Ahhh, that would explain it :-)

Now I have a 512 KB 3.9 ROM containing all the A1200-related updates from OS 3.9 Boing Bag 2, less the workbench.library loaded from hard disk thanks to FindWB from A4000T ROM, plus some BlizKick fix.

Congratulations :-)

Next step, the A4000T release  8-)

I would be interested to hear how you get on with this, since I will hopefully be changing my A1200 for an A4000D fairly soon. Are the chips the same?

@Doobrey
I haven't tried it yet. The thought of dismantling my tower, removing/erasing/reflashing/replacing the ROMs, then rebuilding the tower is too scary to even think about at the moment. The one thing I've learned about Amigas over the years is that if they're working, don't mess with them :-) Mind you, I suppose I could BlizKick the 1MB ROM to test it. Hmmm......

I would definitely be interested in the patch to allow 1MB ROM using the A1200's exec, as I don't have a CD32 to rip the ROM from. If you upload it, let me know please :-)

I don't think so. That driver is an executable programme, not a ROM module. It might be possible to modify the driver so it is BlizKick-able, which would mean you could insert it in to a ROM image. But I don't think it will work in its present form.
