Ok, got myself a Radeon X1600 Pro (klick) which works perfectly allright in MorphOS. And in contrast to my flashed X1900 XT it allows basic Linux usage (console + Xorg via fbdev). Glamour-accelerated Xorg actually loads without crashing the G5 but the screen output is garbled. Filed a bug about that if someone wants to do further research (klick).

So it looks like I can finally get this G5 11,2 going! Only missing a network card now, to get it online and register.

Edit: Realized the X1600 Pro runs well in Linux with xf86-video-ati driver + EXA acceleration. 2D-accelerated desktop & video playback works. So the perfect card for me! OpenGL has glitches however (klick).

Got this i-tec PCEGLAN network card for 7.60 EUR which works perfectly allright. Posting this on the G5 11,2 right now.

I think for the most part, any cheap generic ethernet Realtek PCI-e card will do just fine. :)

Thanks for reporting it!

BTW - None of you are foolish enough to believe that 11,2 and iMac support "just happens" to be included in 10.12, without a lot of work do you?

Remarkable stuff from guys that have day jobs.

I have to check my inventory for any other Radeon supported by MorphOS, otherwise there is not much i can contribute, having the wrong 1900XT and a white screen.

Edit
I found another Radeon, unfortunately unsupported as well.
Its a R7 250 1GB.

Tried out the G5 11,2 now for a while, playing a few games, browsing, emails, copying many files around, etc. Seems to run rather decent. Most of the time I hit the 30min time limit. One time a hard crash, another time fans went 100 % and afterwards a hard freeze. Apart from that I noticed some things in the debug logs:

Code:
Several (all?) games show this r300.library error but seem to run fine apart from that. Tower57 runs really well, but every 2-3 minutes the gameplay 'locks' for 2 seconds. Also some graphical glitches in Virtual GP 2. But nothing really bad. Is my card is (Radeon X1600 Pro) not fully supported?

I noticed some corruption in the video when I went to playback some videos. I went to play Quake 3, and yep... Pixels were color flashing. GPU definitely the problem. :/ This was the x1900 xtx I got last month, and im sure its on its way out. Either then that, my x1900 XT works out great. :)

I generated a MorphOS bug report about my Radeon X1600 Pro issues.

What I noticed too is that MorphOS is rather picky about the PCIe slot my i-tec r8168 network card is in. Old config was Nvidia GF6600 in 1st slot, r8168 2nd, Radeon X1600 Pro 3rd. There the r8169 gets reckognized by MorphOS but has freezing issues when reconfiguring network stack (when I got no connection via static or DHCP). Now I have Nvidia GF6600 in 1st slot, Radeon X1600 Pro 2nd, r8168 4th (1 free slot between Radeon and r8169). There the r8169 runs reliably so far, at least it did not freeze the G5 yet.

Really good card then! As long as you don't miss OpenFirmware.

Quote:
I take that back. Having put the NIC in another PCIe slot only did make it work one time. Now I got the same issue again... Still works in Linux though.

BTW, does it make any difference MorphOS-wise whether I use a RTL8111C, RTL8111E, RTL8111F or whatever revision a RTL chipset has on a NIC?

Quote:
I get these too, but IIRC they're harmless.

This seems to be a bug with gigabit connection. For me the line appears directly after a reboot, but doesn't seem to cause any problems in network tranfers. For some others it can happen in the middle of the transfers and making network to fail. It doesn't seem to happen with 100Mbps connection, so if it's an issue for you, a non-gigabit switch could help until it gets fixed.


Quote:
I get this kind of performance warning even with r200 on Mac mini with Tower57. I asked about it once, but the reply from the MorphOS team was that it should be fixed in the game itself. As the error describes, it makes the game run a bit slower than it could run.

Hmm, interesting... would not have thought about that! Is this an old bug and/or r8169 only? Hope it gets fixed. 100Mbps would be a tad slow for my other machines... Heck, this is slower than USB2.

But I might look for a 100Mbps switch as non-working ethernet is really annoying. Today it worked one time (as I powered on the G5 for the 1st time), but non-working again...

Quote:
Ah mkay. I will tell Daniel then. In general he cares for his code and especially Tower57 has been updated several times.

Thanks for your hints!

Ah well, worked around this rtl8168_eth.device issue by getting one of these PCIe Atheros 5xxx WLAN cards. At last, this works reliably now! Finally it may be the time to register and for my other G5 7,3 to step down into retirement.

Is a long day of hard work

My Ati boards

x600pro
x1300pro
x1900gt (mac flashed)
x1950gt
x2600xt
hd6450

... and as they are laying on the carpet, awaiting their fate to be stroke down by static surges...

edit typo

[ Edited by amifrog 17.04.2020 - 12:46 ]

Oops...... is antistatic carpet, perhaps

None of this boards work, simply my G5 11.2 don't boot... when cd-rom start reading, it stop and show white screen (with ppc rom board, no signal with x86 board). Fan go at full speed and game over

Did you run AHT successfully?

AHT=Apple Hardware Test.

Well, it could be that the CD-ROM drive is simply unable to read the disc well enough to boot. If you can put both a MorphOS-supported Radeon and an NVidia in, get into OF and boot from USB to rule that out.

Hardware is ok, osx work good... now I try with usb boot

Ok, is a cdrom problem, re-burned and now work!

Testing in progress:

x2600xt work good, without 3d (is normal)
x1950gt work good with 3d
x1900gt (mac flashed) not work, white screen
hd6450 not work, black screen

There is a strange thing: MorphOs boot only with original geforce installed (any slot), with only the x86 radeon the cdrom not start loading.

Quote:
Yes, thats some Apple 'feature'... OF needs to see an OF capable card or the machine won't do anything meaningful at all (on any OS).

And thanks for testing all those cards and sharing the interesting results! I had tested an X1550 too which did boot but only showed a garbled Ambient screen. What a pity since this is a passively cooled card which would be ideal for my liking. The X1600 Pro I use now runs fine on MorphOS & Linux but it's fan is the noisiest part of the G5.

Quote:

Once installed on HDD, MorphOS will boot OK without the NVidia, but it's good to keep it around. I have the single-slot height card so I've just left it in.

If I remember well, it has been established on MorphZone for like 6 years with Linux that this is not the case.
