Lisa The Box 10.0
PC speed up utility for Windows 3.1x or Windows 95 and/or DOS 3.2+
Requires:
80286 or higher,
And/or a math-coprocessor chip (Don't try Lisa with just an emulation TSR.)
The FPU chip is preferred to be running at the same Mhz rating as the CPU
(Like a 386/7 25 Mhz AT or MCA clone for instance). However, there are other
architectures that also work.....
8088 or 8086 owners, and those who have a 286 but no math coprocessor; My TSRs
will not work. Don't try to run any of them, your PC may lock up. However, I
have included someone else's public domain program called "Zeno", intended to
speed up the screen.
DOS 3.2 and up. If you run Windows 3.1x, Workgroups 3.1x, or Windows 95 it
works here too. (Will not work in NT or OS/2, which already provide 32-bit and
floating-point services equivalent to Lisa. Not that Lisa won't run, but she
just wouldn't be needed)....
Lisa speeds along stuff like hard disk transfer rate, and graphics mode screen
manipulation. Also, RAM-intensive floating point calculations not specifically
designed for using the math chip will benefit from its use.
______________________________________________________________________________
You should find these files: Tester.Exe, Lisa.Exe, Lisa_2.Exe, Lisa_3.Exe, and
32-Bits.Exe. First, run Tester. This will determine which of the four TSRs you
should run.
Lisa and Lisa_3 both tend to look for six basic operations, five are 32-bit
integer, and one is a general floating-point operation, none of which are
always covered by DOS, Windows, or their applications. What happens is that
when she sees one coming that would generally use software emulation, she
hooks the operation into the hardware instead (physical 386 or 387 chip).
Emulation always takes much longer than the real chip to perform. So, what's
with DOS? Well, it's just that hardware has always been one step ahead of
software. Many operations that could be killed off in a few steps on board a
physical chip, are being re-routed to RAM emulation by default. This is many
steps longer and time-consuming. DOS, Windows, and their applications don't
always expect certain operations. They could be re-written, but the industry
focus is on new operating systems and apps instead (Like OS/2 and Windows NT).
Lisa_2 only provides floating-point services, whereas 32-Bits only provides
32-bit integer services. Like I said, just run Tester and you'll know which
TSR to use. Don't run any two of them at the same time; It's not any harm,
except that this will slow down your PC instead of speed it up. Any of the
four TSRs can be loaded anywhere from within Autoexec.Bat. It may also be
loaded high, if you like. My Autoexec command says C:\util\Lisa and any one
of these TSRs takes up less than 10,000 bytes of RAM according to the DOS
command: MEM/C |More.
About Zeno: This is a public domain utility for speeding up the screen, mainly
in text mode. This is grass-roots shareware at its best, and it has been
modified and refined as it has been passed along. It may be run with any one
of my TSRs at the same time. Zeno will run on anything, even a smoke-choked
13-year old green monochrome IBM 8088 running at 4.7 Mhz. (And no math chip).
"Boxes.Com" is important. If, while you have Zeno loaded it doesn't produce a
neat display of "boxes within boxes" with a message directly in the center,
then Zeno will lock up your computer at a certain point whenever you try to
view a line of text longer than 80 characters. Run "Boxes" before loading Zeno
to see the right display. Also, I have included a sample text file longer than
80 chars called "85chars.Txt". Just put TYPE 85CHARS.TXT at the DOS prompt,
first before Zeno, then after. It shouldn't lock up your PC. If so, you can
fix this by running an ANSI device driver such as ANSI.SYS or ZANSI.SYS from
within Config.Sys. DOS comes with ANSI.SYS. Hopefully you don't have to resort
to this. "Zenotest.Com" is a screen performance measuring tool. You should see
a definite reduction in "screen ticks" after loading Zeno. My old PC would go
from 17 to 4 before and after Zeno. This new one goes from 7 or 6 to 5 or 4.
______________________________________________________________________________
For those of you running Lisa version 8.0, there is a small error in it which
may affect performance. It was corrected in version 9.0.
Also, version 9.0 contained an error which could prevent Lisa_3.Exe from
running on some machines. It was corrected in version 9.1.
Version 9.1 contained no errors, but;
This version, 10.0, has been further optimized for even more performance.
Note: Do not compress any of these TSRs with PkLite or any other executable
file compressor. Exclude Lisa from -any- "on the fly" file compressors;
Stacker is an example; exclude these TSRs from such utilities. (In fact,
no TSR or device driver should ever be compressed in this manner).
