MS600 problems accessing Modem and Remote
Control
A problem has been found on a small number of MS600
Pentium 2 300mhz machines, where the remote control does not work, and the Modem either
does not work or only works erratically.
The problem is caused by a BIOS setting being incorrect
when the PC is switched on for the first time. To check the BIOS press F2 after
switching on the computer, to enter the BIOS setup utility. Then select Advanced,
then Peripheral Configuration. If the machine is affected, then the Serial Port
B Mode will be set to IR-DA.
This setting causes the modem not to configure correctly
when the computer is switched on for the first time, when Windows 95 has to install
and configure any devices present. The modem will be detected correctly, but it will
reside on COM 2 rather than COM 3, therefore causing it to conflict with the remote
control hardware which also resides on COM 2.
To fix the problem, you need to enter the BIOS setup
utility (as described above), select Advanced, then Peripheral Configuration,
then change the setting for the Serial Port B Mode from IR-DA to ASK-IR.
Once changed, press F10 to save the settings and exit the setup utility. To
complete the fix you will need to run the Emergency Recovery Kit, which will
restore the pre-installed software back to how it was when the computer left the factory.
This will allow the Modem and the Remote Control to correctly configure when
Windows 95 starts for the first time.
Note:-
Running the Emergency Recovery Kit will remove any data that has been created on the
computer. Before running the Recovery Kit, make sure that any important data has been
backed up beforehand.
