Description:

Hardware information-gathering tool for VESA PnP monitors read-edid
consists of two tools:

get-edid uses a VESA VBE 2 interrupt service routine request to read a
128 byte EDID version 1 structure from your graphics card, which
retrieves this information from the monitor via the Data Display
Channel (DDC).

parse-edid parses this data structure and outputs data suitable for
inclusion into the XFree86 or X.org configuration file.

get-edid uses architecture-specific methods for querying the video
hardware (real-mode x86 instructions on i386, Open Firmware device
tree parsing on PowerMac) and is therefore only available for i386 and
powerpc architectures.
