Information for Tseng Chipset Users The XFree86 Project, Inc. 13 November 1994 1. Supported chipsets The Tseng chipsets supported by XFree86 are ET3000, ET4000, and ET4000/W32. At this time, the accelerated features of the ET4000/W32 are not supported; the chipset is treated as a standard ET4000. For details about the accelerated ET4000/W32 server, refer to README.W32 . 2. Clock selection problems with some ET4000 boards XFree86 has some problems getting the clock selection right with some ET4000 boards when the server is started from a high-resolution text mode. The clock selection is always correct when the server is started from a standard 80x25 text mode. This problem is indicated when the reported clocks are different when the server is started from the high-resolution text mode from what they are when it is started from the 80x25 text mode. To allow the server to work correctly from the high-resolution text mode, there are some Option flags that may be set in XF86Config. To find out which flags to set, start the server with the -probeonly flag from an 80x25 text mode and look at the information printed by the server. If the line: VGAXXX: ET4000: Initial hibit state: low is printed, put the following in the SVGA, VGA16 and VGA2 sections of your XF86Config: Option "hibit_low" If the line: VGAXXX: ET4000: Initial hibit state: high is printed, put the following in the SVGA, VGA16 and VGA2 sections of your XF86Config: Option "hibit_high" 3. Text mode restore problems In XFree86 1.3, an option flag ``force_bits'' was provided as an experiment to attempt to alleviate text-restoration problems that some people experienced. We have now made the behavior of this option the default, hence the flag has been removed. Hopefully the past text- restoration problems are alleviated in XFree86 2.0. $XConsortium: tseng.sgml,v 1.2 95/01/23 15:34:58 kaleb Exp $ Generated from XFree86: xc/programs/Xserver/hw/xfree86/doc/sgml/tseng.sgml,v 3.4 1995/01/28 16:03:19 dawes Exp $
