Oh... I found in 'Adv. Chipset'...

Anyways, I'm looking for a trick like this one to know the Amiga models :
A3000,
A3000T,
A3000UX,
A4000,
A1200,
A600.

Any ideas ?

Of course "CAFE" is there.

Cosmos · 12 July 2010, 19:58

Yes, but only when 'CD32 C2P' is selected !

Toni Wilen · 12 July 2010, 20:00

A3000: SuperDMAC or FatGary registers, I guess. (UX has no hardware differences)

A4000: A4000 IDE is unique (It is not same as A600 or A1200 IDE) (A4000T = A4000 + non-autoconfig A4091)

A1200: PCMCIA or IDE and AGA?

A600: PCMCIA or IDE and not AGA?

Yes because Akiko C2P is only used if CAFE is there

(You sure you had quickstart really enabled because it surely enables all CD32 options?)

Thanks, I'll see...

And what is the Amiga model using $01000010 ?

It's the A3000T, the A4000T or the Walker ?

I haven't noticed any (official, at least) real Amigas having memory at that location. D.Haynie's A3000+ documentation mentions 0x100000 as a start of chip RAM.

In the 'AmigaOS ROM Update' (WB 3.9)

I checked. It's 0x01000010

Check WhichAmiga source code.

Yes, good idea : for detecting the A3000 and A4000, I'll check Ramsey :

Ramsey rev < $F => A3000
Ramsey rev >= $F => A4000

To check, this is correct ? :

'move.b $00DE0043,d0'

My A3000 have a yellow screen, so I can't test

I must call in supervisor ?

But, it's possible to put a Ramsey from an A4000 into an A3000 ? Works ?

Toni Wilen · 13 July 2010, 14:52

Some A3000 registers are supervisor-only. Don't remember which ones..

But note that randomly reading non-existing memory or registers can and will cause problems on some hardware configurations. Also remember aliasing, most non-AGA Amigas have custom chipset between end of slow ram to 0xdfffff.

It is nearly impossible to get this exactly right, at least without having all possible real hardware configurations

Ok, that's working now...

A new release uploaded !

I think you will cry !

Check Aminet...
