Getting XF86 to run on a C-180 box
Hello.
I have a C-180 Visualize RISC system with a (GSC) "A4070" video card
with a "A4747" daughter card.
The system is happily running with Gentoo Linux, and the swap space
hasn't even been touched...
I would like to get this thing into doing something more than
heating my bedroom, so I am wondering if anyone has a XF86Config file that I could get the video driver settings for the above card configuration.
I have tried "fbdev" but even at Depth=8 I have not been able to get
xfree running.
I searched through the old mail archives but I couldn't find much
more than the "fbdev" setup.
When I do the command line from one of the mail list messages i get
the following.
vorlon portage # dmesg | grep stifb
fb0: stifb 1280x1024-32 frame buffer device, id: 2bcb015a, mmio: 0xf8100000
fb1: stifb 1280x1024-8 frame buffer device, id: 2d08c0a7, mmio: 0xfa100000
I'm not sure what this means, but I think the "-8" and the "-32" is
the depth.
The system RAM is fully populated with 768Megs
If you require any more information, please just ask ;o)

That should work provided you have a "1280x1024" mode defined and set the "fbdev" option to "/dev/fb1". But, I suppose you want fb0, right?

That is correct, and the "1280x1024" corresponds to the resolution as specified in the PDC. IIRC, the A4070-* devices (HCRX family) only worked at this resolution, but might be switchable between 75hz VESA (separate H/V sync) and 72hz (sync-on-green). If your monitor is not receiving a sync signal use a serial console (power-on with the PS/2 keyboard detached, 9600/8/n/1) and try the "co mo" command to view the video setting. "co mo list" should give you a list of options available for each of your two devices.
BTW, you might want to grab copies of the service manual & owner's guide for future reference:
