The chip will hang if it gets corrupted. It's my risk.

Fatal server error: Caught signal 11. Server aborting on my GF2MX200 and ftp://ftp.nest.pld.org.pl/test/athlon/ packages. AFAIR in previous versions (4.2.x) it was working fine. Is it my soft/hardware problem or anyone else noticed the same reaction? I want to reduce memory being used in order to use the rest as a ramdisk. I don't understand that. What does reducing the amount of videoram have to do with a ramdisk? I see no reason to force VideoRam to lower than what there actually is, but if you do it's possible that something in core XFree86 code requires it to be a power of two. Write combine ranges can only be setup on power of two apertures. Nothing in the nv driver has changed in this respect.

I thought the idea up and Michal Schulz gave the solution and detailed description, which you can find at: http://hedera.linuxnews.pl/_news/2002/09/03/_long/1445.html Caution in 5th point misses the true in the last sentence. Is there another way to say to X not to touch specified region of video memory? I see no reason to force VideoRam to lower than what there actually is, As you can see it's good solution for limited memory systems with modern graphics adapters (up to 128MB of VRAM). but if you do it's possible that something in core XFree86 code requires it to be a power of two. Write combine ranges can only be setup on power of two apertures. I've tried 16384, 8192 and 4096 - these are powers of 2. Nothing in the nv driver has changed in this respect. So where's the bug? Reducing works with tseng driver on my second video board - ET6100. -- GoTaR priv0.onet.pl-gotar PLD stuff at http://mops.uci.agh.edu.pl/~gotar/ ___ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
