Operating System: DOS (Note: might work with other versions of this os.)
Put these lines in config.sys
DEVICE=HIMEM.SYS /TESTMEM OFF
DEVICE =nec_ide.SYS /d neccd
Put this line in autoexec.bat
mscdex /d neccd
This may lead to the dreaded dos compatability mode message from win95
so I keep this on a win95 boot diskette along with the many zip drive drivers now available and sys.com to fix partition tables( a last resort).
