TPA (Workstation Memory) Problems
Symptom
Explanation
Solution
An application
that ran in
DOS 1.0.2 and
doesn't run
on DOS 1.1.0.
Most likely
caused by
insufficient
workstation
RAM. DOS
1.1.0, in its
standard
configuration,
has 16K less
TPA than
DOS 1.0.2.
You may
"recover"
most of the
lost TPA.
The compatibility enhancements of DOS 1.1.0 were in
the form of in NSTARI.DRV and ANSI.SYS. Drive C
contains a file called CONFIG. SYS that causes these
drivers to be loaded. It also sets up local MS-DOS
buffers that use more space . The DOS 1.1.0
CONFIG.SYS file looks like this:
device = c:\system\nstarl.drv
device = c:\system\ansi.sys
files=12
buffers=l0
The easiest way to retrieve the lost memory is to get
rid of CONFIG. SYS--perhaps by renaming it. But you
must have NSTAR1.DRV if you are running:
