INSTALLING AND OPTIMIZING QEMM-386 AND QRAM ON THE IBM PS/1

There are a few unusual aspects to the IBM PS/1 computers that must be
addressed in order to install QEMM-386 or QRAM and run OPTIMIZE.

PART I : INSTALLATION

1) The IBM PS/1 boots off a ROM with a built-in CONFIG.SYS and AUTOEXEC.BAT.
These files cannot be changed, which QEMM-386 or QRAM and OPTIMIZE must do.
This may be changed by choosing the "IBM DOS" selection from the opening
screen when the machine boots, then choosing the "Customize How System Starts"
selection from this menu.
In the middle of this screen you will see:

Choose where the computer looks for the operating system:
Start From Built-in DOS
Try Diskette First (Otherwise Start From Built-in DOS)
Try Diskette First, Then Try Fixed Disk

choose the last option "Try Diskette First, Then Try Fixed Disk".

On the bottom of this screen you will see:

When the System Starts From Built-in DOS the Following
Options Can be Set:
Read CONFIG.SYS: Built-in From Disk
Read AUTOEXEC.BAT: Built-in From Disk
Disk to Read From: A: C:

Choose the "From Disk" option for both the CONFIG.SYS and the AUTOEXEC.BAT.
Choose the "C:" option for "Disk to Read From:". This will cause your
computer to boot from the CONFIG.SYS and AUTOEXEC.BAT on the hard disk instead
of from the ROM.

2) The CONFIG.SYS on the hard disk is Read-Only. It must be changed to
Read/Write. This can be done by typing:

C:\DOS\ATTRIB -R C:\CONFIG.SYS

at the DOS prompt, then pressing the "Enter" key.

3) There is a line in the CONFIG.SYS which causes a shell program to be
loaded. This will keep OPTIMIZE from working properly. This line must be
disabled for the duration of OPTIMIZE. This line is:

INSTALL=C:\DOS\SHELLSTB.COM C:\DOS\ROMSHELL.COM

You must insert the word "REM" at the beginning of this line, making it:

REM INSTALL=C:\DOS\SHELLSTB.COM C:\DOS\ROMSHELL.COM

Be sure to use a word processor that does not add any formatting characters.
The program "EDLIN", or "Works", both supplied with your computer, will do
just fine. This "REM" may be removed after OPTIMIZE has finished.

4) You are now ready to install QEMM-386 or QRAM and run OPTIMIZE.

PART II : OPTIMIZE

5) After the first step of OPTIMIZE, the process will halt without
completing. This is due to an obscure bug in the way batch files are executed
in this version of IBM PC-DOS written for the PS/1. This problem is easily
solved. First, edit the file C:\OPT2.BAT. The last line will be something
like:

@C:\QEMM\OPTIMIZE /SEG:xxxx /B:C C:\QEMM\LOADHI.OPT

On a completely new line after this one, insert the word "VER". Don't make
any changes to the original line, just add a new line, with the word "VER".
The end of your AUTOEXEC.BAT will now look like:

@C:\QEMM\OPTIMIZE /SEG:xxxx /B:C C:\QEMM\LOADHI.OPT
VER

Be sure to use a word processor that does not add any formatting characters.
The program "EDLIN", or "Works", both supplied with your computer, will do
just fine.

6) Now run OPT2.BAT by typing:

C:\OPT2.BAT

and then pressing the "Enter" key.

7) OPTIMIZE will now complete. If you desire, you can now reverse step 3.


STEALTH

1) ST:F works on the PS/1. ST:M works only if certain Excludes are used.
These Excludes can be discovered by using techniques described in the
Quarterdeck Technical Bulletin #205, "Stealth Troubleshooting."

2) The obscure bug that causes regular OPTIMIZE to abort prematurely also
causes OPTIMIZE/STEALTH to abort prematurely. The same solution, appending an
extra line with the word "VER" on it, must be applied to OPT1TEST and
OPTAUTO.BAT after the first reboot (then run OPT1TEST) and to OPT2.BAT after
the second re-boot.
