12/28/97 Quake 2 v3.09 patch release notes:

This is an interim release that fixes the most serious problems
with the initial release of Quake 2.  This patch can be aplied to
any released version of quake 2, from 3.05 (on the CD), to 3.08.

There are four files that must be replaced to upgrade:

in the main quake2 directory:

quake2.exe
ref_soft.dll
ref_gl.dll

and in the quake2/baseq2 directory:

gamex86.dll

You MUST NOT have a gamex86.dll in your quake2 directory.
If you installed quake2 over q2test without deleting it,
there may be an old version of gamex86.dll still there.
