Radeon HD PCI 5450 con work with Peg and AmigaOne?

Thanks to one of my friend we found this video board
http://www.club-3d.com/index.php/prod ... ci-noiseless-edition.html

Can be possible it will be usable with RadeonHD Hans drivers and Pegasos2, Sam 440 , AmigaOne?

Letme know can be a really good news have this card working on our old machines

Scroll down, there is a table...

@all
Sorry, I dont know english

@tlosm
Sì, la scheda in questione funziona sulle Sam, su AmigaOne e Pegasos penso non ne valga la pena

@Fogg_80

Mmm, because there isnt the 3D support or because do you Think Will have low performances?in the second case I have a radeon 7750 on pcie-->pci adaptor on a p4 and I can play arma 3 on it plus see full hd mkv

It : xché non c'è ancora il supporto sul 3D oppure perché avrebbe delle prestazioni basse?nel secondo caso ho una 7750 su un vecchio p4 su un adattatore pcie-pci e posso far girare arma 3 oltre a visualizzare gli mkv in full hd senza nessun frame drop

@mr2
I see the compatibility but Will the peg show the video ?i see the note of hans about radeonhd on pegasos and i dont understand if it is related only to video cards on pcie on pcie-->pci adaptor or this is for all video hd cards.

@tlosm

In summary. Radeon HD cards will not work with the Pegasos-II.
PCI RadeonHD has pci->pcie bridge built in. OpenFirmware can not initialize graphic chip behind the bridge. Thats how I understand that...

@mr2

This was my first think about, but is better ask.
if only genesis release open firmware pegasos open sourced :(

@tlosm

I know that card will work with the RadeonHD drivers because I have one in my X1000 (different version but same number) I got mine from amazon as they were cheaper than the specialist sites.

Plenty to choose from here.

It seems to me RadeonHD isn't very interesting on A1XE as long as 66 MHz bus can't be used. If it were, then maybe...

@Thematic
the problem with moderm PCI card it's that generally
the card it's behind a PCI to PCI-E bus and U-Boot
doesn't initialize this type on the 66 MHZ bus,
maybe on the first 33 MHZ one, this it's what
I have understood.
But for a right answer I think we need Hans or
someone else with the right info

@pvanni
only Hans can explain this ,
in all the case will be wonderfull have this video boards working and gallium 3d with aos 4.2 8)

You have hidden WhenIt'sDone somewhere in there.

It's all explained on the page that mr2 linked to (here). In brief:
- Pegasos 2 - forget it; the firmware won't detect the Radeon HD card
- A1-XE (without DMA fix) - will work in a 33 MHz slot; won't be detected when plugged into the 66 MHz slot
- A1-XE (with DMA fix) - partially works; see the compatibility page (linked above) for details

In both cases, things could be improved with a firmware update. That's not going to happen for the Peg2, as their firmware is closed-source and they have no interest in fixing it. Billt intends to look at fixing UBoot for the A1-XE, but there are no guarantees or time-frames.

The best option remains to upgrade to a PCI-Express capable machine like the Sam460ex or A1-X1000 (or A-EON's project Cyrus board, when it's done).

The slow PCI bus will impact performance; but, the real reason why the 5450 will have low performance is because it's a low-end card. Your 7750 is significantly faster. The difference in GPU power will be much more noticeable when 3D drivers arrive.

@Hans

Thanks for the explanations.
Soon we will start an email bombing to the Genesis with some other friends with pegasos2 hope they will release a opensourced open firmware or just gave the opportunity to some one to fix this .
