-Mesa-5.1 release notes:
------------------------
+Requirements:
+-------------
+
+A Voodoo-based videocard/accelerator
+DOS (with DJGPP), Windows9x/2k (with MinGW), Linux
+Glide3x library for your OS
+
+http://sourceforge.net/projects/glide/
+
-1) Glide2 support has been ceased; in order to keep Voodoo Graphics, Voodoo2
- and Voodoo Rush compatibility, please visit the Glide SourceForge and help
- us to fix Glide3 for those cards.
-2) The non-DRI Linux build is currently broken. Any help will be appreciated.
-3) Glide3 can be found at http://sourceforge.net/projects/glide/
-Known supported HW: Voodoo Banshee, Voodoo3, Voodoo4, Voodoo5 5500
-Known supported OS: DOS (DJGPP), Windows9x/2k (MinGW/MSVC), Linux+DRI
+How to compile:
+---------------
+
+DJGPP:
+ Place the Glide3 SDK in the top Mesa directory:
+ $(MESA)/glide3/include/
+ 3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+ $(MESA)/glide3/lib/
+ libgld3x.a, libgld3i.a, glide3x.dxe
+ Type:
+ make -f Makefile.DJ X86=1 FX=1
+ Look into the makefile for further information.
+
+MinGW:
+ Place the Glide3 SDK in the top Mesa directory:
+ $(MESA)/glide3/include/
+ 3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+ $(MESA)/glide3/lib/
+ libglide3x.a, glide3x.dll
+ Type:
+ make -f Makefile.mgw X86=1 FX=1
+ Look into the makefile for further information.
+
+Linux:
+ Place the Glide3 SDK in /usr/local/glide
+ /usr/local/glide/include/
+ 3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+ /usr/local/glide/lib/
+ libglide3x.a, libglide3x.so
+ Type:
+ make linux-glide
+ or
+ make linux-x86-glide
+
+
+

-Hiroshi Morii <koolsmoky@users.sourceforge.net>
+FX_DEBUG
+ enable driver debug code
+FX_TRAP_GLIDE
+ enable Glide trace code
+FX_PACKEDCOLOR
+ use packed color in vertex structure
+FX_TC_NAPALM
+ map GL_COMPRESSED_RGB[A] to FXT1. Works with VSA100-based cards only.
+FX_COMPRESS_S3TC_AS_FXT1_HACK
+ map S3TC to FXT1
+FX_RESCALE_BIG_TEXURES_HACK
+ fake textures larger than HW can support
+ (see MESA_FX_MAXLOD environment variable)
+
+
+
+Environment variables:
+----------------------
+
+The following environment variables affect MesaFX. Those that affect Glide
+only, are beyond the scope of this section. Entries that don't have a "Value"
+field, can have any value whatsoever
+ ex: set MESA_FX_IGNORE_CMBEXT=y
+
+"Note" (*) means that the environment variable affects Glide, too; also, if
+the var is not found in the environment, it is searched in windoze registry.
+"Note" (!) means that the environment variable is not working as expected;
+may have undefined effects, might have effects only at Glide level or might
+not have any effect whatsoever. Caveat emptor! Those are to be revised soon.
+
+It is recommended to leave the envvars alone, so that Mesa/Glide will run with
+default values. Use them only when you experience crashes or strange behavior.
