This is most likely a limitation of the MorphOS 2.7 driver to avoid hardware (mouse)crsr corruption (which only works properly in the first 128mb segment).
As there was not much to gain by additional 128MB for 9600/9800 cards in 2.7, I limited the address space to 128MB.

This is the related change in 2.7:

Devs/Monitors/Radeon
o Fixed hardware cursor support on some Radeon 9600 and Radeon 9800 cards

I reworked this some time ago and it should work ok for the next update.

Frank's answer
In OSX and Linux there are 256Mb vram available

If interested in "benchmarks" with this very good card in OSX, look at here (Quake 3 and Quake 4) http://www.nonsoloamiga.com/forum/viewtopic.php?f=67&t=131 http://www.nonsoloamiga.com/forum/viewtopic.php?f=19&t=136

Thanks. So it's not the Mac ROM limiting the VRAM (and also not two apertures according to pega-1).

stephen_robinson,

So, as no-one answered my question... do you remove the resisters* or flash first?

if you remove the resisters will it boot on a PC for flashing, if not should I flash first?

or the other way, if it's flashed will it boot on a PC?


Okey, done it. I flashed first, after I'd flashed there was no display on the PC, (but it seemed to be booting, so I suppose it could have been reflashed from the backup.rom file, if I typed it all in right without anydisplay), then I removed the resisters, which was dead easy, (I'd imagine putting them back on would be horrific!) and it booted up correctly on my dual 533, didn't try it my dual 1.42 as the molex power cables are too short, I'll have to send off for some extenders.

Anyway:-

this Youtube video was quite useful:

But this is the best site for advice:

the atiflash can be downloaded from

for a USB bootable stick the HP USB Stick Formatting Tool can be downloaded from
http://www.techpowerup.com/downloads/330/.html

but it seems to lack the actual dos system files to make it bootable, probably due to copyright issues. so dunno where to find them

Well got it all working, but blimey the card runs hot, the back (ie the bit without the fan) of the card is unpleasant to touch, I'm putting it down to the room heater of the CPU cooler sitting under the graphics card and the heat rising into the card. I've not even 'Overclocked' the card to the correct speed either.

I can't under stand how a single core 1.5mHz macMIni can run so cool, but a dual 1.42 with a heatsink larger than the whole MacMini runs like a 1 bar electric heater.

without the 3d graphics drivers it really doesn't like Lucy!

G5 X800 cards don't work in a G4.
But I currently have a PC card (R420 based) flashed with Mac BIOS and it works great in my Quicksilver.

BTW - Hery Frank, any chance of you and Bigfoot resuming work on a driver for the R400s?
We don't need G5 support to run one.
