Borland/Ashton-Tate has confirmed that dBase III version 1.0 and dBase III+
version 1.0 may cause your system to stop responding (hang) if HIMEM.SYS is
installed.
CAUSE
dBase III 1.0 and III+ 1.0 include a feature called SuperLock that
conflicts with HIMEM.SYS. According to Borland/Ashton-Tate, SuperLock is a
copy-protection feature that allows you to install dBase III 1.0 and III+
1.0 only once to a hard drive.
WORKAROUND
Adding the /CPUCLOCK:ON switch to the HIMEM.SYS line in your CONFIG.SYS
file may resolve this conflict. If you are using dBase III or III+, add the
following line to your CONFIG.SYS file
device=[drive]:\[dir]\himem.sys /cpuclock:on
where "[drive]" and "[dir]" indicate the location of the HIMEM.SYS
driver.
The /CPUCLOCK:ON switch slows HIMEM.SYS, allowing it to wait longer for
signals. This affects the speed of HIMEM.SYS, but not the system clock
speed. Early versions of dBase were written for slower machines.
