The Trident driver has undergone major work for XFree86 3.1.2B. Because of this work, all of the Trident SVGA chipsets, except the very first one, are supported by both the color and monochrome servers.
8800CS 8200LX 8900B 8900C 8900CL/D 9000 9000i 9100B 9200CXr 9320LCD 9400CXi 9420 9420DGi 9430DGi 9440AGi 9660XGi 9680 Cyber9382 Cyber9385It must be noted that the 9000i chipset is treated as a 9000 by the server. Additionally the 9100B is treated as a Trident 8900CL. Therefore it is equivalent to putting `
Chipset "tvga8900cl"
' or
`Chipset "tvga9000"
' in the XF86Config
file. Also,
note that the 9000i, 9100B have not been tested with the server,
but should work in this way according to the chipset documentation.
NOTES:
Turn off linear mapping
Force linear mapping. Use this if you have a non-PCI card and require 16bpp support. Note: ISA cards can only access up to 16MB of memory, so be sure you have less than this or it could cause a system hang.
This option may be used to specify the start address of the linear frame buffer. By default for VLBus/EISA cards it is at 60MB. For the 8900CL/D, it is at 15MB.
45ns DRAM
70ns DRAM
80ns DRAM. This is the default for TGUIs. NOTE: The above settings allow for higher dot clocks. Choose the one that matches your DRAM speed.
Turn on hardware cursor (NOTE: it is off by default)
Turn off PCI burst read mode.
Turn off PCI burst write mode. NOTE: PCI Burst modes are now on by default. If you suffer from screen corruption, you might like to try and specify one or both of the PCI options above.
Turn on programmable clocks. This is the default for TGUIs.
Turn off programmable clock. Use fixed VGA clocks only. Useful for fixed frequency monitors - usually used for VGA monitors - not SVGA.
The original Trident chipset, 8800BR, cannot be supported as an SVGA chipset by either the color or monochrome servers. The chip is supported, however, by the ``generic'' driver for the monochrome server.
