------------------------------------------------------------------------

1.      Overview

	This package contains a tools to set the video refresh rates
	for different resolutions on the ELSA WINNER 100/1000/2000
	graphics boards.

	The current version of this tool is 1.04 edit level 2.

	In chapter 5.1 you can find a list of the supported BIOS
	versions.

	Pay attention to the modification of the refresh rate for the
	WINNER 100VL by this utility. The Windows program ELSA WINman
	reports "VESA" for the refresh rate and can not be modified
	there.


------------------------------------------------------------------------

2.      Contents

	The following files are contained in this package:

	REFRESH.EXE     the executable program file.

	REFRESH.DOC     this file containing the release notes.
	REFRESH.DOK     the German version of the release notes.


------------------------------------------------------------------------

3.      Installation

	To use this tool, copy the executable file(s) from this
	package to a directory on your hard disk. This directory should
	be included in the PATH environment variable.

	To permanently use this tool, it should be used in the
	AUTOEXEC.BAT file to set the video refresh rates every time the
	system starts.


------------------------------------------------------------------------

4.      Notes

4.1     Usage and command line syntax

	REFRESH.EXE provides the following command line options:

		-i[nfo]         Show a summary of the currently active
				video refresh rates.

		-s[how]         Show complete information for all
				video refresh rates available on the
				WINNER board. Active settings are
				marked with an arrow "-->".

				See below for the format of the output
				produced by this option.

		-b[ios]         Show a list of BIOS versions supported
				by this tool. The version of the BIOS
				installed on the WINNER board is also
				shown.

		-q[uiet]        Suppress normal messages from the
				program. This option may be useful when
				using the program in the AUTOEXEC.BAT
				file.

		-h[elp]         Show a list of available command line
				options. The same list is shown when
				REFRESH.EXE is called without any
				command line options.

		-r[ate]640=<RATE>
		-r[ate]800=<RATE>
		-r[ate]1024=<RATE>
		-r[ate]1152=<RATE>
		-r[ate]1280=<RATE>

				Set the video refresh rate for the
				given resolution to <RATE>. Only the X
				axis resolution is given. The refresh
				rate may be given in Hz or as a number
				in the range of 0 to 3 as reported by
				the -show option.

				See below for an example of how to use
				this option.

		-vgastd         Set refresh for VGA modes 0 thru 13 to
				standard VGA timing (31.5kHz
				horizontal retrace rate).

		-vgahigh        Set refresh for VGA modes 0 thru 13 to
				high refresh timing (35.1kHz
				horizontal retrace rate).


4.2     Format of the reports produced by REFRESH.EXE

	The -show and -info options produce output in the form of a
	table showing active and available refresh rates.

	Below is an example of this table produced by -show. columns
	are marked for the explanation below.

		(A)     (B)      (C)  (D)   (E)     (F)   (G)
	     --------------------------------------------------------

		      640x 480 @ 72Hz     37.86kHz  (3)
		-->   640x 480 @ 60Hz     31.47kHz  (2)
		      800x 600 @ 72Hz     48.09kHz  (3)
		      800x 600 @ 60Hz     37.88kHz  (2)
		-->   800x 600 @ 56Hz     35.16kHz  (1)
		     1024x 768 @ 70Hz     56.48kHz  (3)  4/8 bpp
		     1024x 768 @ 60Hz     48.36kHz  (2)  4/8 bpp
		     1024x 768 @ 50Hz (i) 41.42kHz  (1)  15/16 bpp
		-->  1024x 768 @ 43Hz (i) 35.52kHz  (0)
		     1280x1024 @ 60Hz     63.34kHz  (2)
		-->  1280x1024 @ 43Hz (i) 48.58kHz  (0)

	     --------------------------------------------------------

	In detail, the columns of the table contain the following
	information:

		(A)     This column contains an arrow for the currently
			active refresh rates (-show option only).

		(B)     The screen resolution in horizontal and
			vertical pixels. The first (horizontal) value
			is the one to use with the -rate option.

		(C)     The vertical refresh rate. These values can be
			used with the -rate option together with the
			corresponding horizontal resolution from column
			(B).

		(D)     An (i) in this column marks interlaced video
			timings.

		(E)     This column shows the horizontal retrace
			frequency of each refresh rate. Check this
			number with the specification of the monitor in
			use to see wether a refresh rate is supported
			by the monitor.

		(F)     This column shows the refresh mode selector
			that kann optionally be used with the -rate
			options.

		(G)     For some resolutions, not all bit depths may be
			supported with the same refresh rates. This
			column shows which bit depths are available
			with the resolution and refresh rates from
			columns (B) and (C).


4.3     Examples

	a) Show current settings

		refresh -info

	This will show the current setting of the video refresh rates.

	b) Show current settings and available refresh rates

		refresh -show

	This will show all refresh rates available with the video BIOS.
	The currently active settings will be marked with an arrow
	("-->") symbol.

	c) Set refresh rate for 640x480 resolution

		refresh -rate640=72

	The refresh rate for 640x480 modes will be set to 72 Hz.
	Information about the active settings is printed as with the
	-info option.

	d) Set refresh rates and show full info

		refresh -rate640=72 -rate800=60 -show

	will set the refresh rates for 640x480 and 800x600 to 72Hz and
	60Hz, respectively. Complete information about current and
	available refresh rates is printed.

	e) Set refreh for standard VGA monitors

		refresh -rate640=60 -rate800=56 -rate1024=43

	will set refresh rates that are supported by standard VGA
	monitors with 31.5 and 35.1 kHz horizontal retrace rates.

	f) Set standard VGA mode timings to fast refresh

		refresh -vgahigh

	will set the horizontal retrace for standard VGA modes to
	35.1kHz, resulting in a reduction of screen flicker.


4.4     Command line shortcuts

	Most of the command line options may be abreviated to a singls
	letter as indicated by the square brackets as in -h[elp] or
	-r[ate]640.

	Therefore the following command lines are identical:

		refresh -rate800=60 -show
		refresh -r800=60 -s

	Note that blank space before the resolution ("800" in the
	example above) is not allowed.


4.5     Problem reports

	In any report on bugs, problems or errors with this tool,
	please state the exact program version, command line options
	and other circumstances in effect when the bug, problem or
	error was observed. This will greatly help tracking down the
	problem.

	The following versions of the WINNER 1000ISA VGA BIOS are
	supported by this tool:

		1.00.00 and later

	If your WINNER board has a newer version of the BIOS, you can
	get the next version of this tool to support this BIOS version.

	New versions of this tool will be available on the ELSA BBS.


5.2     Refesh rate selection for VGA modes

	Command line switches "-vgahigh" and "-vgastd" have been added
	to change standard VGA mode timings to high or standard refresh
	rates, respectively.

	The switch is not supported by current versions of the 1000PRO
	and 2000PRO BIOS.


5.3     Unsupported BIOS versions

	Some temporary or beta releases of the WINNER VGA BIOS are not
	recognised by this tool. Therefore, refresh rates cannot be
	changed with these BIOS version. You should update your WINNER
	VGA BIOS to the latest release to use this tool.


------------------------------------------------------------------------

6.      Caveats / Known Problems

6.1     Old BIOS version 2.13

	The old BIOS versions 2.13d and before are not supported by
	this tool. They do not allow changing the refresh rate on their
	video modes.


6.2     Permanent setting

	This tool does not allow permanent setting of refresh rates. It
	has to be run each time the operating system is started.

	This is easily achieved by placing a call to the tool in the
	AUTOEXEC.BAT file.


6.3     VGA modes high refresh timings

	The timings produced by the "-vgahigh" command line switch are
	no common standard timings. Therefore, not all VGA modes may
	look fine on all monitors.

	Furthermore, changing the VGA mode refresh rates is not
	supported on all WINNER boards. You will see a message if this
	is the case.
