I picked up a little something interesting that I thought might be of use to Linux-users or would-be-Linux-users. ---- From: erik@westworld.esd.sgi.com (Erik Fortune) Newsgroups: comp.sys.laptops,comp.windows.x Subject: Re: Video Chips & Xfree: WD90c24 Date: 11 Jul 1994 19:30:27 GMT Message-ID: <2vs6kk$kb1@gazette.esd.sgi.com> References: <dernst.41.000C8069@pppl.gov> In article <dernst.41.000C8069@pppl.gov>, dernst@pppl.gov writes: > So ... does Xfree support 1024 x 768 x 256 on the WD90c24 chipset? > If not, is there a driver out there that does?

Xfree 2.1.1 supports it (in 640x480x256, at least) by treating like a WD90C30. The WD90C24A (and A2) is accelerated. Xfree 2.1.1 recognizes it as a WD90C24 and supports it (at 640x480x256) but does not take advantage of the acceleration. The blitter/cursor are compatible with the WD90C31, so if you have a WD90C24A you should specify the chipset to be wd90c31 in your Xconfig file. I haven't tried X on the external monitory, but my INSI ECHObook (identical to the Everex STEP Note and a nice machine, btw) seems to have a strange memory configuration. According to the Western Digital documentation, my WD90C24A2 reports 512K, but I am able to run windows in 1024x768x256 on an external monitor. I'm hacking around with the server as time allows (i.e. not very much) and if I figure anything out, I'll send it back to the Xfree folks. Cheers, Erik ------- Preetty interesting. What video chip do we TP75x owners have? The WD90C24, WD90C24A, or WD90C24A2? And has anyone managed to get SVGA on a TPxxxC?
