@Hans


I tested my 7750 at a friend's place on his 64 bit windows 10 PC and my 7750 is working correctly from bios/boot to OS with drivers installed.





and we tested a couple hours of Tux kart. for science.


Next time I'm there I will dump the bios and compare it to the
bios from TechPowerUp, that didn't spring to mind then but for now
I think that this points toward that the bios is likely intact.

My atombios seems to be newer than TechPowerUp's bios though

Mine
015.025.000.002.000000 2012-09-21 04:39:00

Theirs
015.021.000.000.000000 2012-06-11 02:59:00

A quick google search hints that it is legitimate as it is also used by
Sapphire's 2GB version of the 7750 and their 2GB 7870

@Hans

My 7750 boots 32 bit Windows XP just fine, both via native PCIE and via the PEX8111 adapter.

Sorry for the lack of information regarding the atombios

The old PC I have for testing is unstable and it does not have any free space on the C drive for me to install the drivers, so video card dianogstic programs such as GPU-Z won't function.


I thought it would be good anyway to let you know while I'm looking for a 32 bit CMD program to scan the atombios.

I didn't notice that the debug buffer would not empty after a warm reboot

PCI BIOS ROM signature... as in legacy parallel PCI?

@TSK

I have tried that but as there is no "Board 1" (7750) to select from
I have no idea how to procede any further.

That while the system can find the 7750, it doesn't use it as a graphics board.

So a program such as software rendered Quake can only find Board 0, the 9250, and no other board.





Ranger sees the 7750 in the PCI Bus tab while simultaneously doesn't show it in the list of graphics boards (graphics board list being pressed down here)





and indeed this is reflected in Screenmode prefs




The 7750 is connected to a different monitor (HP Compaq LA 1956x) with different specifications (1280x1024@75hz, Horizontal refresh 24-83khz. Vertical 50-76hz), I also tried switching the monitors by swapping the DVI cables at the cards' end with no success.

Connecting the 7750 via VGA will make it boot at a lower resolution of
720X400 instead of 1280X1024 but made no further difference.

The last port the 7750 has is a mini HDMI port, I have no mini HDMI to DVI adapter to test it at the moment.

There's also mini display port but I think that isn't supported at the moment even with a DVI active adapter, right?

PCIGraphics already has some manual modes and I also tried booting with detect settings automatically.

Interesting, so it might be worth plugging in it a Windows PC and see if there's a newer version of the bios to flash?

e.g. https://www.techpowerup.com/vgabios/12 ... pphire-hd7750-1024-120611

@Rob @Hans

So I deleted the RadeonHD monitor driver, dublicated the ATI Radeon driver and
changed it to PCIGraphics

Reboot and..





Progress! "Command" is no longer Disconnected!


But it still didn't mount as a graphics board, double clicking
the new monitor driver still gives the same error message.


Gave a shot at making Picasso96 screenmodes but the 7750 didn't show
up in the list of devices, only 9250 or assign to no board.


Is there a program for AmigaOS that is similair to device manager on Windows? so that I can enable/disable PCI boards?

or is there anyway to "poke" the 7750 to life in OS4?
it still only shows a blackscreen with a blinking text cursor.

And is it normal that the 7750 doesn't have a 'display controller' but the 9250 does?

@Rob PM sent!

@Rob

@Rob @nbache


Thank you so much for your suggestions Rob and Niels.


I dublicated the old monitor driver in Ramdisk and named it RadeonHD with
CMPLENGHT adjusted.



When I double click it I get this error





I am fairy new to AmigaOS, so how would I know that this monitor is
assigned or trying to assign to the 7750?


At least it shows up in my screenmode prefs.




But unfortunately while the 7750 is regonized as a VGA controller, it doesn't actually get "mounted" as
a graphics board.

There is only graphics board 0/1, the 9250




I also tried renaming the ATI Radeon driver 'Radeon9250' and now when I reboot the 9250 uses the RadeonHD
monitor driver :P

I have a dvd drive with OS4 by hand so if something goes wrong I can always boot off the disc and revert any
changes I made,
so go nuts with your suggestions!


Curiously, looking in my OS4 FE disc there are three seperate driver monitors for the permedia, radeon and
3dfx voodoo.

The Radeon and Voodoo monitor drivers have identical settings and are identical in size, so why would there
be a need for two seemingly identical monitor
drivers? perhaps there's more than that meets the eye?

Perhaps a Radeon HD user could PM me their monitor driver or would that not allowed here since it could be
considered part of a commercial product?





I don't think that the issue lies with the PEX8111 adapter.

PCI cards without any bridge chip and bridge chips themselves resides in "PCI bus 0" (according to uboot's
PCI scan command)

AGP & 66Mhz cards resides in bus 1

Any card behind a bridge chip resides in bus 2 and higher,

My 7750 resides in bus 2. (PEX8111 is in bus 0)

I also have this multi I/O card with a Sil3112 sata, NEC USB and firewire chips connected with a bridge chip
which resides in bus 3 and it works flawlessly,
typing this with a usb keyboard connected to that card.

I can also rearrange the cards IRL so that the 7750 is in bus 3 and the multi I/O card is in bus 2,
which makes no difference, Multi I/O is fine and 7750 bails out at the OS4 loading splash screen or is
asleep when I boot with AGP.

@Rob

Good one! I haven't thought of that.


No, there is no new monitor driver installed, there is only 'Radeon' for the
old ATI cards.


Can I just dublicate the old Radeon monitor (to e.g. RadeonHD) and change its boardname tooltype to the new card?




if so, what is the boardname of my 7750?

Could anyone please give me the boardname of their 7750 / Radeon HD monitor driver?

As a quick guess I changed it into "RadeonHD" but that didn't do it.





Or is it not that simple and do I need a specific Radeon HD monitor driver?

I can't find one in my Enhancer pack installation files.

@Rob

Version 53.15 from 10/13/2016


and my RadeonHD.chip is 2.22 from 03/25/2017, probably a newer version is available via enhancer's updater
but I still need to wait for my Amisphere account to be fixed.

A-eon's outdated contact captcha isn't helping.

Finally.




I do not recommend buying from Sedna directly, as they can be quite slow to respond to emails.

E.g. it took something of a month to arrive and I was promised a tracking number which I still haven't recieved.



Anyway, the card turned out to have a PEX8111 chip (as stated on their website) and is correctly working




Best of all, the 7750 gets initialised during Uboot!
and is fully working!


After this I reinstalled my Radeon 9250 and purchased. downloaded and installed the Radeon HD v2 driver within the Enhancer software pack.

Swapped out the 9250 and put in the 7750 in a 33mhz pci slot,

OS4 kickstart loading and... nothing



It hasn't hung as the text cursor was still blinking but I noticed that the RadeonHD.chip
wasn't loaded.

Booted OS4 with the 9250, checked out kicklayout in the kickstart folder and sure enough it wasn't added to the list.

While it is my first time installing the Radeon HD driver, surely it should be automatically be added?

So I manually added it in, placing it underneath the the ATIRadeon.chip





Booting with the 9250 again removed and 7750 installed,

RadeonHD.chip loaded and.. out of range

Black screen, No OS4 loading splash screen.


So i tried booting with both the 9250 and 7750 in the hope that I could get past the OS4 loading splash screen and configure the card in OS4 but that doesn't work,
as only one of the two cards will get initialised, the other card will sit idle with a black screen and blinking cursor.

But I can investigate with the 9250, Sysmon properly detects the 7750 with chipset name and model numbers (7750/8740/250E)




Ranger also detects the 7750 alongside the 9250, "Command: disconnected"





A posseble solution I'm thinking of is disabling the IDE DMA and "USB DMA" as stated on Hans de Ruiter's HDRLab
I'm not sure how to quickly check if my AmigaOne has the DMA fix for ide, but I have onboard IDE and USB disabled in uboot and commented out of my
kickstartlayout which doesn't seem to help.



So at the moment I'm stuck, I am having issues with my Amisphere account so I can't go onto the A-eon forums yet.

Here a link to an archive with my kickstart layout file, more pictures of the cards and pci detection software
and videos of booting with the 7750 and what the 7750 is doing during OS4 with the 9250 installed.

http://www.filedropper.com/pex8111-7750

I recently purchased a low profile Sapphire Radeon HD 7750 on eBay, with the 7750 I also purchased a PEX8112 Pci to Pci express x16 adapter for use with my AmigaOne XE.

The next day I received a message from the pex seller saying that it wasn't in stock anymore, it turned out that the supply of the card has dried up everywhere online.

Most places that sell the adapter only sell in bulk and the very few places that still sell them individually do so at a price of around 100$.



I figured that the only way the get the adapter is here from other Amiga users, as the PEX8112 was recommended by Hans de Ruiter for use with the Sam440 motherboards.




I am willing to pay for it and I will certainly post benchmarks when the 7750 is working, will be interesting to compare the bandwidth advantage of the AGP Radeon 9250 vs the massive power increase of the 7750 on PCI.


So could anyone spare their Pex card? or could anyone point me to where I can obtain the card inexpensively?

Both will be very appreciated.

@LiveForIt

There isn't anything major from preventing such a cooler to work on the X1000, should it be compatible with the X1000's mounting holes, the GPU just has to be inserted in the lower Pcie 16 slot.



"I guess if have passive cooler like that you bend the motherboard, if stands up right, I think this might not be so good idea."

I'm not a fan of such a heatsink design either, but billt asked where one can get the MagmaColluseum cooler, which I think is a rebranded Nofan CR-95C as can be seen on this archived page.

https://tinyurl.com/MAGMACoolers



@tonyw

60mm square? that's too bad as it seems that neither Intel or AMD ever used such dimensions so A-EON users can't use common PC coolers.

I guess Marcus made custom mounting brackets for the Magma coolers.

@billt

Would be nice to know what mounting holes the X1000 and X5000 uses

@virgola

If you're part of the Power Progress Community then please consider using Patreon in addition to fund the project.

So that if the goal isn't met after this milestone announcement (new wave of donations dies) then that the funding doesn't become stagnant and the project eventually get cancelled.



If you're not aware of Patreon, it is a website where a individual or organization can create a account and others can then donate to that account on a timely basis (eg weekly, monthly) or per milestone.



I think that multiple 10 Euro donations per month would aid the funding significantly.

It's not as much as a couple hunderd Euro donations per milestone but at least the project eventually will get funded.


Best of luck!

@xenic


19200hz is Paula territory, that's why we love it!

@LyleHaze

I'd love to recommend the X1000 but that is a rather expensive soundcard ;)

@m1nuto

Neat, does your card come with a gameport?

Hi @Antique

The Envy24HT cards Spectre pointed out are also the best quality cards that you can buy for AmigaOS 4, Envy24HT is the only supported chip on OS4 that supports 24 bit depth with 192000hz sampling rate.

The Envy24HT is also available on 'regular' Pci cards, such as the M-Audio Revolution 5.1 / 7.1, a nice fit for the Pci slots on the X5000

Even Pcie x1 is more than three times faster than the old Pci interface.
(500 MB per sec vs 133MB per sec)

In my opinion it would be a waste to use one of the Pcie x1 slots for just a soundcard, so I would make it a priority to find a Pci Envy24HT card instead of a Pcie x1 card.

On your system partition should be a list of Envy24HT cards that are reported to work

System partition (OS4)>Documentation>AHI>Envy24HT.doc



Another safe bet is to use a card based on the CS4281 chip,
which is capable of 16 bit at a samplerate of 48000hz.
Here is a thread in which m1nuto, a X5000 user, got a CS4281 card to work.

http://www.amigans.net/modules/xforum ... php?topic_id=7347&forum=4

There I also go indepth about the Soundblaster 128 and Live!



If you bought a complete system then it is likely to be supplied with a CMI8738 soundcard and you might have to enable it in the AHI prefs.

Something I spotted on tech websites which i think will interest AmigaOS4 users.

Marseille recently released a HDMI cable with an inhouse ASIC intergrated to anti-alias video, with 3D games specifically in mind.


http://www.marseilleinc.com/mcable-gaming-edition/


Linustechtips made a video review of it, at 4:30 they show off Quake 2 and Unreal at 480p which I find to be really impressive.

https://youtu.be/MjJzibFTaqA?t=4m30s
(link starts at 4:30 mark)


This is excellent for older AmigaOnes/Sams with R200 graphics cards, with a DVI to HDMI passive adapter.

As those machines are held back by the old Warp3D api and the (i think) cpu heavy minigl wrapper, they do not perform well with 3D games.

On my AmigaOne XE with a 7457 @1066mhz and 128 bit R280, I am stuck playing Quake 3 at an ugly 800x600 further blurred on a HD monitor,
I'm not sure if Warp3D supports anti-aliasing outside the 3DFX Voodoo 5 if it even supports anti-aliasing at all.

I am temped to buy this, however I actually rarely play games on my AmigaOne
and unfortunately the cable is designed towards Consoles thus there is noway of telling the cable to stop anti-aliasing.

So it will try to anti-alias the workbench as well.


I imagine that you would need to have a short HDMI extension cable hanging from your display and one HDMI Y-splitter cable connected to your video card and connect the mCable and a normal HDMI cable to it.

Have the normal cable connected to the extension cable with the mCable lying on your desk and whenever you want to play games you swap the cables.



The cable is rated for 1080p @ 120hz, there is also a "cinema" version of the cable which only difference there is i think is that it rated for 4k60 video.

This cable is also shown in the Linustechtips video at 6:24 and again looks awesome.
https://youtu.be/MjJzibFTaqA?t=6m24s

The cable also complements the system's native/internal anti-aliasing well so it is also future proof for newer PPC machines/NOVA.


So what do you guys think of this?

Typing this on my AmigaOne XE
