1 Information for W32 Chipset Users

Contents of this section

XF86_W32 is basically XF86_SVGA with the drawing code completely replaced with one based on X11R6's mi/cfb code and modified for the ET4000/W32 series. Even though it accepts the same keywords as XF86_SVGA, those not applicable to the ET4000/W32 series are silently ignored; e.g., the keyword "SpeedUp" is a no-op. The server currently supports the w32, w32i, and w32p chips. For a complete list, see the sign-on message printed by XF86_W32. The server only supports 256 colors.

Just as with XF86_SVGA, you can specify a virtual world that has a width that is a multiple of four. The size of the virtual world is constrained by the amount of the available video RAM. XF86_W32 can use more than 1 M of video RAM, but it reserves 1 K for internal use. If you have 1 M, XF86_W32 claims you have 1023 K; you get to specify the virtual world as 1152x900, but not 1152x910.

The current maximum clock is set to 86 MHz according to the Tseng databooks. For a non-interlaced 1280x1024x(256 colors) at say 135-MHz, you need a w32p (with its 16-bit RAMDAC bus) with a multiplexing RAMDAC so that the w32p sees only (135/2 = 67.5) MHz, not 135 MHz. This requires special code that is not currently provided.

If you have problems with the server. Try the following:

Note that the built-in power saver (for a "green" monitor) has not been tested. Also do not expect it to work on a board without a w32p_rev_c or later chip.
