  upgrade is needed to build)
- Update to 1.50: ftp://ftp.microsoft.com/softlib/mslfiles/nmake15.exe

SETTING THE BUILD ENVIRONMENT:
The path should include the bin directories from MASM and MSVC, as well as the
normal path for DOS or Windows.
Following is a sample batch file to set up the environment:

@echo off
if "%varset%" == "xpath" goto done
set path=c:\tools;c:\tools\masm\bin;c:\tools\msvc\bin;%path%
set lib=c:\tools\msvc\lib
set varset=xpath
:done

BUILDING THE ROM:
Change directories to vsa_ii\build and type NMAKE. This will create the
VSA .bin file.

Build Targets in the Makefiles:
• NMAKE all - builds the VSA binary
• NMAKE clean - cleans up last compile, but leaves the VSM files.
• NMAKE cleanall - cleans up last compile completely
