13 Known Issues and Important Notes

13.1 Support for MS Windows XP

AMD recently announced to provide drivers for MS Windows XP. They are already available on the AMD developer web.

Note

There will be no ofcial release or support from congatec for these XP drivers.

13.2 Graphics Memory

In BIOS Setup, the graphics memory is set to 256MB (default). If there are 4GB Ram installed Windows 7 (32Bit) provides only 2.69 GB system

memory. In order to increase the available system memory, the graphics memory can be reduced to e.g. 128MB in BIOS Setup. In order to

increase the graphics performance (e.g. Blueray playback) the graphics memory can be increased to e.g. 512MB in BIOS Setup. Graphics

memory should be set to a xed value.

13.3 AMD “Eyenity” Support

Currently the AMD graphics driver does not yet provide support for Eyenity (e.g. combine two displays). Support is expected from June/2014.

13.4 HDMI Audio Support

HDMI audio transmission is not yet supported by the released driver.

An appropriate driver including HDMI support is expected from beginning of June 2014 (Driver version ≥14.20). In order to use HDMI audio in

advance, AMD provides a specic DVI-HMDI dongle (OPN: 199-999269).

13.5 Audio: Recording Level via HDA Front Panel

Recording via HDA audio front panel is very quiet. This hardware-related issue will be solved with the upcoming conga-IGX variants.
