║ Classic Above Board Problems in Compaq Computers ║
║ ║
╚═════════════════════════════════════════════════════════════════════════╝
COMPAQ DESKPRO 286 & 164, 201 MSGS.
Compaq systems need to have all motherboard sockets filled before
trying to add additional memory to the system.
COMPAQ EXPANSION UNITS & ABOVE BOARDS
There have been customer reports that Above Boards may not be reliable
in COMPAQ expansion units.
COMPAQ PORTABLE ROM CONFLICT
We have a field report that Rev E of the Compaq Portable (8088 based)
ROM will not support our EMM 4.0. The customer stated that he
installed a Rev. J of the ROM and the problem went away.
COMPAQ SYSTEM PROBLEMS
If, after adding an Intel product, (such as an Inboard, Above Board, or
Math Coprocessor), the COMPAQ Deskpro 286 system suddenly begins to
reboot itself automatically, here's some help. This is usually a
symptom of one or two things.
First the power supply could be failing and the Intel product could be
taxing it beyond its capabilities. The only solution is to replace the
power supply.
Second, and something to check BEFORE replacing the power supply, is a
defective connection between the power supply and the motherboard.
This will allow the system to operate until (a) an additional burden is
placed on the power supply, or (b) enough oxide builds up on the
connection, causing the system to exhibit the failure. The cure for
this is to vigorously "reseat" the connection a couple times. Be
careful to not apply excessive force and break the connector or
motherboard.
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.
