NEATFIX.DOC
PURPOSE:
--------
The NEATFIX program changes the programming of the Chips & Technologies 286 NEAT chip
set, specifically in the CompuAdd 220 (286/20 Mhz). The bus, as programmed by the CompuAdd
BIOS, will not allow the Artisoft AE2 adapter (16 bit Ethernet card) to operate correctly in 16 bit
mode, and causes the machine to hang at various times. This program should ONLY be used
in a CompuAdd 220. Its effect is to change the bus' mode from asynchronos to synchronous
operation. NEATFIX is provided as an interim solution, the user is urged to upgrade the 220
BIOS. CompuAdd Corp. released a new BIOS version in late January, 1991 that programs the
bus controller correctly.
Artisoft, Inc. assumes no liability for any damages resulting from the use or mis-use of this
program.
OPERATION:
----------
NEATFIX is run without any arguments, and should be placed in the computer's AUTOEXEC.BAT
file to be run at boot time. Since it changes programming which the machine's BIOS puts in
place, it must be run each time the computer is booted or rebooted. It must be run before any
Network Operating System (NOS) software is installed, and should be run before any TSR
application. To assure that it is run first, copy the NEATFIX.COM file into the root directory of
boot disk of your computer. Then add the line:
NEATFIX
to the AUTOEXEC.BAT file, using an ASCII file editor. This line should be placed somewhere
near the top of the file, preferably near the PATH and/or PROMPT statment(s). Save the changes
you've made, then reboot the computer.
To return the computer to original bus programming, remove the NEATFIX line from the
AUTOEXEC.BAT (or REM it out) and reboot the computer.
NEATFIX MESSAGES:
-----------------
NEATFIX will return one of 2 messages:
Message: "The Bus has been synchronized."
This message will appear if NEATFIX is successful in changing the bus programming.
Message: "NEAT chipset not installed. Nothing done."
This message will be returned if the bus is not a NEAT chipset or the program was unable to
change the programming for an undertermined reason.
