This machine is a Dual P5-166. |I can not run any larger resolution, the machine gets overloaded. Looks |like it is not doing DMA. (Blast from the past. I know.) Exactly. AccelX does not have DMA support last I heard. XFree86 does (via the XF86VidMode extension). So on AccelX, the CPU and system memory are always in the middle of a triple-stage image copy, assuming your server's XImage format is compatible with the Bt chip. If not, it's worse.
