Production Team,

Please be aware that the Matrox G200e graphics driver for the Supermicro X8SIL-F motherboard (Compucon Workgroup Server) only supports a resolution of up to 1280x1024 by design. Please see the following note extracted from the G200eW Release Notes below, which includes two (2) methods of adding support for a specific desktop resolution. Method 1 is to add support into the driver for a specific system whereas Method 2 adds support for all systems into the driver. Please note that the new resolution will break KVM redirection should the user or reseller attempt to use it.

PRODUCT INFORMATION
-------------------

Matrox G200eW (Nuvoton), version 1.02.005
January 15th, 2010

HIGH AND WIDESCREEN RESOLUTION SUPPORT
--------------------------------------

The driver supports only a limited list of resolutions by default.
The list consists of 640x480, 800x600, 1024x768, 1152x864, 1280x1024.
This limitation guarantees that KVM redirection will always be functional with these modes.
The KVM supports upto 1280x1024 resolution.

There are two methods to add high and widescreen resolutions to the list.

method 1)
Add the following section to the MtxSetup.ini files located in the X32_WHQL and X64_WHQl folders

[AddReg.0532.xxxxyyyy]
HKR::Mga.SingleResolutions:BINARY:\|
80,02,e0,01,\|
20,03,58,02,\|
00,04,00,03,\|
80,04,60,03,\|
00,05,D0,02,\|
00,05,00,03,\|
00,05,C0,03,\|
00,05,00,04,\|
50,05,00,03,\|
78,05,1A,04,\|
A0,05,84,03,\|
40,06,84,03,\|
40,06,B0,04,\|
90,06,1A,04

where xxxx -stands for subsystem ID (SSID) and
      yyyy - subsystem vendor ID (SVID)
  
SSID and SVID should be copied by the system BIOS to the Matrox PCI configuration space (offset 0x2C/0x4C).

Eash line represents one resolution. 80,02,e0,01,\| for example means 0x0280 X 0x01e0 resolution (640x480),
i.e the encoding uses 16 bit values in little endian format.
The list can be changed if it is required.

This way will work only for a specific system. If the SSID changes from system to system or
the System BIOS does not copy the values to the PCI configuration space the second methods can be used.

method 2)
Add the following section to the MtxSetup.ini files located in the X32_WHQL and X64_WHQl folders

[AddReg.0532]
HKR::Mga.SingleResolutions:BINARY:\|
80,02,e0,01,\|
20,03,58,02,\|
00,04,00,03,\|
80,04,60,03,\|
00,05,D0,02,\|
00,05,00,03,\|
00,05,C0,03,\|
00,05,00,04,\|
50,05,00,03,\|
78,05,1A,04,\|
A0,05,84,03,\|
40,06,84,03,\|
40,06,B0,04,\|
90,06,1A,04

This way all the systems with the installed g200ew driver will support the new resolution list.
