The current S3 Server supports the following S3 chipsets: 911, 924, 801/805, 928, 732 (Trio32), 764 (Trio64), 864, and 964. The S3 server will also recognise the 866, 868 and 968, but it has not been tested these chipsets. If you have any problems or success with these, please report it to us.

Nevertheless, this is not enough to support every board using one of these chipsets. The following list contains some data points on boards that are known to work. If your card is similar to one of the described ones, chances are good it might work for you, too.

S3 801/805, AT&T 20C490 (or similar) RAMDAC

  - Orchid Fahrenheit 1280+ VLB
  - Actix GE32

  8 and 15/16 bpp

  Note: the AT&T20C490 RAMDAC is not automatically detected by the server. You need to provide a ``Ramdac "att20c490"`' entry in your `XF86Config`.

  Real AT&T 20C490 or 20C491 RAMDACs work with the `"dac_8_bit"` option. Some clones (like the Winbond 82C490) do not.

S3 805 VLB, S3 GENDAC (RAMDAC + clock synthesizer)

  - MIRO 10SD (available for VLB and PCI) It is not known whether all 10SDs use the S3 GENDAC.

  8 and 15/16 bpp

  >      ClockChip "s3gendac"
  >      RamDac    "s3gendac"

S3 801/805, AT&T 20C490 RAMDAC, ICD2061A Clockchip

  - STB PowerGraph X.24 S3 (ISA)

  8 and 15/16 bpp

  Note: the AT&T20C490 RAMDAC is not automatically detected by the server. You need to provide a ``Ramdac "att20c490"`' entry in your `XF86Config`.

S3 805, Diamond SS2410 RAMDAC, ICD2061A Clockchip

  - Diamond Stealth 24 VLB

  8 bpp only.

  requires ``Option "nolinear"`'

S3 928, AT&T 20C490 RAMDAC

  - Actix Ultra

  8 and 15/16 bpp

  Note: the AT&T20C490 RAMDAC is not automatically detected by the server. You need to provide a ``Ramdac "att20c490"`' entry in your `XF86Config`. Also, the server's RAMDAC probe reportedly causes problems with some of these boards, and a RamDac entry should be used to avoid the probe.

  Real AT&T 20C490 or 20C491 RAMDACs work with the `"dac_8_bit"` option. Some clones (like the Winbond 82C490) do not.

S3 928, Sierra SC15025 RAMDAC, ICD2061A Clockchip

  - ELSA Winner 1000 ISA/EISA (``TwinBus'', not Winner1000ISA!!)
  - ELSA Winner 1000 VL

  8, 15/16 and 24(32) bpp

  Supports 8bit/pixel RGB in 8bpp and gamma correction for 15/16 and 24bpp modes

  24 bpp might get ``snowy'' if the clock is near the limit of 30MHz. This is not considered dangerous, but limits the usability of 24 bpp.

  D-step (or below) chips cannot be used with a line width of 1152; hence the most effective mode for a 1 MB board is about 1088x800x8 (similar to 2 MB, 1088x800x16).

S3 928, Bt9485 RAMDAC, ICD2061A Clockchip

  - STB Pegasus VL

  8, 15/16 and 24(32) bpp

  Supports RGB with sync-on-green if `"sync_on_green"` option is provided and board jumper is set for BNC outputs.

  VLB linear addressing now occurs at 0x7FCxxxxx so that 64MB or more main memory can be supported without losing linear frame buffer access.

  Option `"stb_pegasus"`

  The `"dac_8_bit"` option is always selected on this board.

S3 928, Bt485 RAMDAC, SC11412 Clockchip

  - SPEA Mercury 2MB VL

  8, 15/16 and 24(32) bpp

  Option `"SPEA_Mercury"`
  ClockChip `"SC11412"`

  The `"dac_8_bit"` option is recommended.

S3 928, Bt485 RAMDAC, ICD2061A Clockchip

  - #9 GXE Level 10, 11, 12

  8, 15/16 and 24(32) bpp

  Option `"number_nine"`

  The `"dac_8_bit"` option is recommended.

S3 928, Ti3020 RAMDAC, ICD2061A Clockchip

  - #9 GXE Level 14, 16

  8, 15/16 and 24(32) bpp

  Supports RGB with sync-on-green

  Option `"number_nine"`

  The `"dac_8_bit"` option is recommended.

S3 864, AT&T20c498, ICS2494 Clockchip

  - MIRO 20SD (BIOS 1.xx)

  The ICS2494 is a fixed frequency clockchip, you have to use X -probeonly (without a Clocks line in XF86Config) to get the correct clock values.

  8, 15/16 and 24(32) bpp

S3 864, AT&T20c498 or STG1700 RAMDAC, ICD2061A or ICS9161 Clockchip

  - Elsa Winner1000PRO VLB
  - Elsa Winner1000PRO PCI
  - MIRO 20SD (BIOS 2.xx)

  8, 15/16 and 24(32) bpp

S3 864, STG1700 RAMDAC, ICD2061A Clockchip

  - Actix GraphicsENGINE 64 VLB/2MB

  8, 15/16 (and probably 24(32)) bpp

S3 864, 20C498 or 21C498 RAMDAC, ICS2595 Clockchip

  - SPEA MirageP64 2MB DRAM (BIOS 3.xx)

  8 and 15/16 bpp

  ClockChip `"ICS2595"`

  Clockchip support is only preliminary and on some machines problems with the first mode after startup of XF86_S3 or after switching back from VT have been seen; switching to next mode with CTRL+ALT+``KP+'' and back seems to solve this problem

  Mirage P64 with BIOS 4.xx uses the S3 SDAC.

S3 864, S3 86C716 SDAC RAMDAC and Clockchip

  - Elsa Winner1000PRO
  - MIRO 20SD (BIOS 3.xx)
  - SPEA MirageP64 2MB DRAM (BIOS 4.xx)
  - Diamond Stealth 64 DRAM

  8, 15/16 and 24 bpp

  ClockChip `"s3_sdac"` (should be detected automatically)

S3 864, ICS5342 RAMDAC and Clockchip

  - Diamond Stealth 64 DRAM (only some cards)

  8, 15/16 and 24 bpp

  ClockChip `"ics5342"` RAMDAC `"ics5342"`

S3 864, AT&T21C498-13 RAMDAC, ICD2061A Clockchip

  - #9 GXE64 - PCI

  8, 15/16, 24(32) bpp

  Option `"number_nine"`
  Option `"dac_8_bit"` (recommended)

S3 964, AT&T 20C505 RAMDAC, ICD2061A Clockchip

  - Miro Crystal 20SV

  8, 15/16, 24(32) bpp

S3 964, Bt485 RAMDAC, ICD2061A Clockchip

  - Diamond Stealth 64

  8, 15/16, 24(32) bpp

S3 964, Bt9485 RAMDAC, ICS9161a Clockchip

  - SPEA Mercury 64

  8, 15/16, 24(32) bpp

  Option `"SPEA_Mercury"`

S3 964, Ti3020 RAMDAC, ICD2061A Clockchip

  - Elsa Winner2000PRO PCI

  8 bpp only

S3 964, Ti3025 RAMDAC, Ti3025 Clockchip

  - Miro Crystal 40SV
  - #9 GXE64 Pro VLB
  - #9 GXE64 Pro PCI

  8 bpp, 15, 16 and 24(32) bpp

  Option `"number_nine"`

  There are some known problems with the GXE64 Pro support, including some image shifting/wrapping at 15/16/24 bpp.

  We have found that #9 no longer support the GXE64 Pro at 1600x1200. They do however have a new (and more expensive) board called the GXE64Pro-1600 which uses a 220MHz RAMDAC instead of 135MHz part used on the other boards. It is not known at this stage whether the GXE64Pro-1600 will work with XFree86 3.1.

S3 764 (Trio64)

  - SPEA Mirage P64 (BIOS 5.xx)
  - Diamond Stealth 64 DRAM
  - #9 GXE64 Trio64

  8/15/16/24 bpp

  Note: there are some display wrapping problems with the Trio64 at 8bpp which have not yet been fixed.
