Novabridge will not work because it need RadeonHD V5. And RadeonHD V5 is not available for the sam440.

Sailor said she wanted to try SAM460 RadeonHD v5 driver with SAM440. Both chips has the same core. I wonder what the result is....

Sam440ep + RadeonHD v5 (Sam460ex version) not works.
It is not exact - it boots to system, but performace is not good an va.libraty not works, so it is useless.

And regarding NovaBridge - I suppose that it works with RadeonHD v3.7. I will test it also and let you know.

This is the part I was interested in. As far as I remember NovaBridge should work with RHD 3.7....anyway, thanks for the info :) We both know that asking to release a special version for SAM440 is useless ;)

Thanks for the valuable info.

And yes "I am the friend" in question. So if either me or or him use the expression "my friend" we are not using a common low security phrase to describe ourselves.

It's funny that I initially had my long post here then thought I should separate it. I might as well kept it here. Or posted it to the stuttering thread.

In research I've actually found a 5450 PCI card. Perhaps good also for the XE as it may be a good way to upgrade if it works. While useful for use on a PCI system it's limited in power these days.

So possibly any card from 4 to the 6 series would be good. But, despite being popular in the X1000 era, they lack support for 3d. I purchased an XFX 4890 for my X1000 back in the day which is a monster. But really was wasted on my system if it wasn't used for 3d, which wasn't popularised on OS4 like it is now, and I didn't use it for any Linux 3d gaming either.

What's confusing is the cards work in UBoot which gives the impression it has enough power. So would this mean it only used low power in basic VGA modes? And for opening a real screenmode in 32 bit HD it needs more power to do so?

On the subject of the PEX8111/PEX8112 are there any HD cards that do work on this chipset? Mind you that means getting into the high end one you widen it from HD 7xxx to R9. It would be rather disappointing if the driver was holding it back and preventing the PEX8111/PEX8112 from working if it could. That would mean possibly working hardware rendered useless by a driver quirk.

The common example for the PI7C9X111SL chipset is the StarTech card. Unfortunately this means another expensive add on is needed. Of course this is the result of using legacy technology in PCI. It's getting closer to a Classic Amiga at this stage, with the PCI add ons, where you needed expensive PCI bridges just to add an old or cheap PCI card.

It also looks "inferior" to the PEX based one as it only has 1x lane where as the PEX one has full 16x lanes. So you pay more for less. Neither one has a power input necessary to fulfil the PCIe power standard.

BTW I did find a PCIe power injector. Looks expensive. Riser card may be better as it's common and cheap to get. Plus if it can only work with 1x PCIe bridge no point with a full slot. Otherwise a possible PCI power injector may have solved that as well. That less likely to exist.

What I meant with power injector is the cheap risers used for crypto mining. He already bought that one. It's a PCIe x1 to PCIx16 solution with a USB cable in between. The power is injected to the x16 slot by means of a 6-pins PCIe power cable, 4 pins molex cable or a SATA cable

Afaik, HD7000 don't even show u-boot output without the riser/power injector described above

Sure, his HD 5450 work with it. Just no HD 7000 series work with those PEX8111/PEX8112 bridge/adapters

Looks can be deceiving They are both 33/66MHz PCI to single lane PCIe 1 bridge chips. So there's only one lane connected in your x16 slot.

Yes, the Startech one is the only one that I could find as well. But they already start from ~EUR 37 on Amazon.

Yes, I know what you meant there, I was just wondering if there was a neat solution to supplying power to bridge cards. The riser solution ends up being like a hack as the video card needs to then sit loosely in the case. Which is somewhat worse that lacking a long threaded screw to hold it in a PCI bracket.

Unfortunately I didn't take any notes when testing hardware. I tested both R7 240 and HD 7770 in bridge card as well as in powered riser. With and without power in riser.

Given the performance difference and lack of 3d support under HD 7000 cards not much point then.

Well that's typical. Then the 1x board going into the 1x socket from a USB cable would suit it then. I suppose that's neat.

Any chance there is a RAIL adapter version that instead of having a tiny adapter at the end of that usb cable, it has the full length pcie?

Was just curious.

AFAIR r = recall,

When you were testing it on your xe1, did'nt none of them work not even showing up Ubooot?

No, I gave up, I couldn't get any to work. At first I couldn't get any to fit in the PCIe bridge as I was unable fit a plug on the back of the cards. I was able to fit a cable to the 5450 but even that was a lost cause.

Despite the physical connection another issue was the 66Mhz slot and AGP slot share the same bus. So the firmware or UBoot must be set to change modes before plugging anything in. I found this out after the fact and almost fried the cards as I wasn't aware of it when testing.

So, for my XE, it's actually harder to install a HD card than a Sam 440.

According to https://www-amigaportal-cz.translate.g ... x_tr_hl=de&_x_tr_pto=wapp
it only works in a PCI33 slot, not in the PCI66 one, only with interrupts disabled in the monitor driver tooltypes, and not with a "DMA-fixed" (i.e. completely destroyed) AmigaOne.

Today has no big sense to try PCIe HD card on AmigaOne XE.
It works, but problem is that new RadeonHD drivers mostly not works with XE.

Like joerg mentioned, you have to use 33 MHz slot, DMA-unfixed machine, and also PCI interrupts are not initialized.

The last can be corrected XE - hw interrupts, but speed is still low.

My summary is, that Sam440ep-flex is much better with RadeonHD card, XE with HD card is worse.

But I am not tred Nova Bridge on XE, maybe compatibilty is higher than Warp3D-SI.

Bummer :{

It is a shame that XE hardware is proving to be so unconfigurable :{
