║ ISA Bus: Symptoms/Solutions: Parallel/Serial Port and Clock Problems ║
║ ║
╚═════════════════════════════════════════════════════════════════════════╝
CLOCK.SYS (FOR THE PS-PC ONLY)
CORONA DOS 3.1 & CLOCK.SYS
Symptom: CLOCK.SYS always returns Msg. 101 on boot up. Corona DOS 3.1
apparently resets the clock chip on AB PS-PC. Have user try using MS-DOS
or PC-DOS. Lower versions of Corona DOS potentially have the same
problem.
DIAGRAPH AND CLOCK.SYS
Diagraph graphics software is incompatible with many DOS device drivers.
If you have problems using the Above Board clock with Diagraph Version
3.4, try the ABCLOCK program (available from the Intel Bulletin Board
System).
NORTON UTILITIES AND CLOCK.SYS
The early Norton Utilities "System Information" (SI) command returns an
error message if the AB Clock device driver is installed. To use SI,
remove the clock device driver and reboot.
Current versions of Norton Utilites potentially have the same problem but
this is unknown at this time.
OFFICE WRITER & CLOCK.SYS
Will not run properly with our clock installed. Office Writer looks for
time at INT 1A and is not changeable; CLOCK.SYS uses INT 2. The Office
Writer folks can be contacted at ph: (608) 274- 5047.
"PC TO MAC AND BACK" AND CLOCK.SYS
"PC to Mac and Back" is software that runs on a PC and allows you to
communicate with a MAC via serial port.
In a computer with an Above Board PS/PC "PC to Mac and Back" won't work if
the Above Board's clock is active. Remove the CLOCK.SYS device driver or
switch off the clock.
LOSS OF TIME OR DATE ON COLD BOOT
Check IBM PC power supply. If it says 'manufactured in Mexico', this may
be the problem. They will probably need to upgrade their power supply to
remedy this situation.
"SLOW" CLOCK PROBLEMS
The clock on the Above Board PS/PC is warranteed to 0.05% accuracy. This
amounts to approximately +/-5 minutes per month, or about 10 seconds per
day. If a clock is operating within these parameters, it is NOT
defective. This level of accuracy is consistent with that found in all
other manufacturers' boards.
CAN'T SET TIME AND DATE
If you're unable to set the time and date, make sure you have the latest
clock software, and remove the VERIFY ON command (if it exists) from the
AUTOEXEC.BAT file. Contact Intel's Customer Support or Intel's Bulletin
Board System for the latest software.
BREAKTHRU 286 TURBO (BY PCSG)
Users report this computer uses the same I/O ports as the Above Board
PS/PC's clock and returns clock message 101. Contact Intel's Customer
Support or Intel's Bulletin Board System for the latest ABCLOCK software.
INVALID DATE OR TIME MESSAGE
If you receive this message even after resetting the date and time
correctly, you may have a dead battery on your Above Board PS/PC. If you
do NOT have an Above Board PS/PC, the computer's battery keeping the CMOS
memory on the motherboard active might need replacing.
The battery on the Above Board PS/PC is designed to work for 1 year. The
Above Board PS/PC uses a 3-volt, H coin battery you can find at many
computer dealers, electronic stores and camera shops.
Some part numbers for batteries that will work in the Above Board PS/PC
are:
MANUFACTURER PART#
------------- ------
PANASONIC BR2325
RAY-O-VAC BR2325
PANASONIC/MATSUSHITA BR2325
PARALLEL PORT
PARALLEL PORTS
DOS assigns the names LPT1, LPT2, and LPT3 to parallel ports according to
the number of parallel ports in the computer and the I/O address each
uses. You can have up to three parallel ports in your computer only if
LPT1 is on the IBM Monochrome display Adapter or its equivalent.
Otherwise DOS limits your computer to two parallel ports (LPT1 and LPT2).
When you turn on or restart your computer, DOS checks for parallel ports
first at I/O address 3BC, then at 378, and finally at 278. The first port
it finds becomes LPT1, the second LPT2, and the third LPT3. The SETBOARD
program lets you name the Above Board's port.
You can't set the Above Board port to I/O address 3BC. This address is
reserved for video boards that contain a parallel port.
If you have only one parallel port in the computer, DOS always names it
LPT1, regardless of the I/O address it uses. If you have two parallel
ports, DOS assigns LPT1 to the port using the highest address.
SERIAL PORT MISSING IN COMPAQS
Problem: Compaq Deskpro 286 can't recognize a serial port on an Above
Board's Serial Port.
The problem is Compaq's Diagnostic disk. If you run diagnostics on the
system with an Above Board PS/286 or Plus I/O installed, the Com2 port
goes away until you cold boot. Proper installation is as follows:
1. Install Above Board, run Setboard, make the comm port COM2 (use
default interrupt 3).
2. Install serial software
3. Do NOT run COMPAQ diagnostics.
Diagnostic versions 5.07, 5.08 and 6.01 all produce the same problem. If
diagnostics are run, a cold boot will get things back to normal again.
DETECTING PORTS WITH DEBUG
If you're having a problem determining which ports (parallel and serial)
the computer is using, you can check for the I/O ports using DEBUG.
Follow these steps to use DEBUG:
1. Change to the directory containing the DEBUG program and type
"DEBUG".
2. At the DEBUG prompt, a dash, type "D 40:0" and press Enter.
This will display the hexadecimal values of the active I/O port
addresses, first serial then parallel. Here's an example:
C>debug
-d40:0
0040:0000 F8 03 00 00 00 00 00 00-BC 03 00 00 00 00 00 00
-q (to exit DEBUG)
This display indicates one serial port installed at 3F8 and one parallel
port installed at 3BC.
TIME IS OK, BUT DATE IS WRONG
This is caused by Compaq DOS Ver. 2.11 and lower and also by some versions
of PC DOS 2.1. It is a DOS problem and the only fix is to upgrade to a
higher version of DOS.
A customer reported that using Compaq DOS Ver. 3.1 on a Zenith 151 caused
the same problem when the machine was configured with three COM ports
(COM3 being a Hayes internal modem). Problem disappeared when modem was
removed.
