I tried forcing the driver to recognise the 7543 as a 7548, which didn't seem to work. It only recognized 512K of video ram, which doesn't allow me to drive the thing at 800x600 with a decent resolution. -----Original Message----- From: Matan Ziv-Av [mailto:matan@svgalib.org] Sent: Saturday, November 09, 2002 1:25 AM To: Marc E.

I've searched the mailing list archives, I've used google on news No work was done on the cirrus driver in a long time. There seems to be support for the 7548, though. It is possible thsat forcing the cirrus driver to recognise your card as a 7548 might be enough to make it work. > groups and the web, and I've peeked into the source release of both svgalib > 1.4.x and 1.9.x source release.

All datasheets were available from cirrus' weebsite. Unfortunately, they are not there now, and I did not download the LCD controllers datasheets. You idea of porting the code from the X driver to the svgalib driver should work with no problem. -- Matan Ziv-Av. matan@svgalib.org ------------------------------------------------------------------ Unsubscribe: To: listbot@svgalib.org Body: unsubscribe linux-svgalib
