Does somebody know exactly, which are first Radeon cards with AtomBIOS?

I did't find exact list or chip number, from which AtomBIOS is used.
It is somewhere between R400 and R500.
R500:
Best graphics... Best video ... Peg2 died AGP cards...
R400:
More Radeon ... AMD video ... whats he building in there....

It is not only academic question, I want select PCIe cards ( RV370 and newer ) but without AtomBIOS to test it with Efika + PCI-PCIe bridge.

Indeed, early AtomBIOS versions came somewhen during R400 series, but I also couldn't find out from which GPU/card on exactly. The reason I've been mentioning AtomBIOS to start only with R500 series here on MorphZone is that, as far as I understand, the AtomBIOS parser contained in MorphOS requires the newer AtomBIOS versions that started with the R500 series. I've now added a corresponding explanation to those comments to prevent future misleading.

Please, are there somebody with linux and graphics card with chips:
RV370: X600 variants (X300, X550, X1050 not in MOS compatible)
RV380: X600 PRO/XT
RV410: (X550, X700, X1050 not in MOS compatible)
R423: X800 variants
R430: X800, X800GT
R480: X800 variants, X850 variants
It can be any PC with Intel or AMD, not only PPC, with opensource driver (amdgpu, radeon).

Can I ask you if you can try the "dmesg | grep ATOM" command? To check if there are ATOM BIOS or not. And please post here the result.

Many thanks.

I have a X300 lying around and I think (?) a X600. I can check them on the weekend. AFAIK the X300 did not show up with AtomBIOS in the logs... But well, I schould rather check it.

After searching in TechPowerUp BIOS collection I found, that all Rx4xx cards which are on database are with ATOMBios:

RV410: X550 ATOMBios, X700 ATOMBios, (X1050-not in database )
R423: X800 ATOMBios
R430: X800 ATOMBios, X800GT ATOMBios (not all variants in database )
R480: X800 ATOMBios, X850 ATOMBios (not all variants in database )

For simplification we can expect, that all Rx4xx Radeon chips are with ATOMBios.

For testing remains:
RV370: X600 variants (X300, X550, X1050 not in MOS compatible)
RV380: X600 PRO/XT

Many thanks, ernsteiswuerfel!

I'm not exactly sure what you are aiming at but even if a Radeon card has a so called AtomBIOS, it still has all the legacy BIOS functionality required by a X86 BIOS emulator.

Also, even if R4xx cards have AtomBIOS support, it isn't supported by the current MorphOS driver anyway. It requires at least a R5xx chip equipped card to be supported.

There are no R(V)3xx equipped cards that use any kind of AtomBIOS afaict.

The aim is to test on Efika more "modern" cards then Radeon 9800.
Here some results from testing.

In short, MOS supported HD4350 cards doesn't work in Efika, and more, after a minute serial debug returns mesh of chars and efika don't boot to MOS.
These card differs from 9xxx/R300 cards with three things:
radeon chip: but HD4350 PCI works with Pegasos2 MOS
PCI-PCIe bridge: PCI versions have PEX8112, PCI-e version with PEX8111. But X1900 G5 (PPC bios) with PEX8111 boots with Efika - no screen, card not recognized, but bridge chip is the same as I tested with HD4350, so bridge is probably no reason of Efika stuck.
AtomBIOS: Radeon 9xxx have "classic" x86 bios and OF of Efika (and Pegasos) have emulator for it. And cards newer then R500 (and all R400 as we found) all have Atom bios. I don't find exactly with which chip ATOMBios was started.

So it looks that main reason why Efika don't boot is ATOMBios. Yes, it is only my theory.
Then I ask about rest of chips greater then Radeon 9xxx - i.e. now only RV370 and RV380 if they have Atombios or not. I am not sure, I don't find it on ATI related pages.

If they cannot have ATOMBios, it makes sense to test them with Efika, as it probably most "modern" cards, which can be usable.

I can see how this theory somehow contrasts with what cyfm just wrote ;-) But please go ahead, then we'll know for sure.

Many theories cotrast with something. They are theories

From cyfm there is usable info "There are no R(V)3xx equipped cards that use any kind of AtomBIOS afaict." Unfortunatelly there is no link to some official source, but we can take id as a premise. I thought so too.

Second info "Radeon card has a so called AtomBIOS, it still has all the legacy BIOS functionality required by a X86 BIOS emulator" is also true, but all functionality <> 100% code compatible.

Without deeper knowledge of Efika firmware (or reverse engeneering of it) I have no other easy solution then search for card differencies. And ATOM bios is one the significant. And up to now fits in theory.

Partial (up today) conclusion is, that make sense to test only one other card: Radeon X600 XT. No Atombios, with bridge, newer then R350.
Unfortunatelly I have no one in my proximity, so I have to wait if some Efika user has, or wait for one.
I also suppose, that this card cannot be faster then 9800PRO, but if it will be very close, it is better solution for me: 9800PRO 47W, X600XT 25W, Efika <= 3W.

The only person who knows about internas of EFIKA or Pegasos OpenFirmware, very well, is Nicolas Det from BPLAN. He has written PEG/EFIKA-relevant parts of OF and has also done some low-level drivers for MOS. I think it would be a good idea to ask him about that issue.

So much for more theories but feel free to go ahead, whatever floats your boat ... :)
Nicolas Det definitely was involved in the development of EFIKA's OF but the actual BIOS emulator used in both Efika & Pegasos has originally been written by Gerald Carda@bplan

@ernsteiswuerfel:

Many thanks! So X300 (RV380) have no ATOMBios.
Cards with it have output like this:
Code:
```
# dmesg | grep ATOM
[    0.752011] ATOM BIOS: TURKS
[    2.434756] ATOM BIOS: Tahiti
```
So I mean, that we can close this subject with this result:
All Radeon chips upto R3xx don't have ATOMBios, and
all Radeon chips from R4xx have ATOMBios.

Many thanks for testing!
