My AGP graphics card
Posted: Sat Aug 31, 2013 5:15 am
Hi,
I was wondering if development is still continuing on AGP Radeon drivers or if the focus now is on PCI/e graphics cards (or is that an irrelevant question, and future developments will work regardless of the bus)?
The reason I ask is because of my own graphics card. In my A1-XEI have an AGP Radeon 9250 256MB/128-bit. It appears to be this card here: http://www.amazon.co.uk/ATI-Radeon-256M ... B002Z3J6RS . Here is my benchmark at Hans' site: http://hdrlab.org.nz/Benchmark/GfxBench2D/Result/1122 .
It seems to have a few quirks, although I don't know if this is because the OS4 driver isn't 100% compatible or perhaps there is a fault.
Firstly, for some reason, with the card in place and attached via DVI to my Dell monitor, it takes 45 seconds from power-on to uboot appears. I read somewhere that during boot up, the VRAM is mapped (or something), but recently when I was at a friend's place I connected my A1 via VGA to a different monitor, and uboot appeared instantly. Is there some sort of handshaking going on via DVI?
I initially tried the card under and older update og OS4.1.x, and only 128MB showed as useable. I therefore put the card aside and continued using my old 128 MB/64-bit Radeon 9250, but came back to it late last year and was surprised to find Workbench now reports the full 256 MB.
It seems all 256 MB is addressable, and I have got it quite low sometimes. However, if I have less than approx. 128 MB free and I open a new screen, that screen is usually garbage. If I pull down a working screen to reveal the new screen behind it, it comes up fine. In a few rare instances, opening a new screen with less than 128 MB free makes all open screens garbage.
Here's how Ranger reports the card:
It would be nice to have all 256 MB accessible flawlessly, but as I said I don't know if that's down to the driver or some other factor. It would also be great to eliminate the wait on boot-up (it can be nail-biting when I've been doing some work under the hood, and waiting anxiously to see the machine boot ).
