SYMPTOMS
When you set up American Power Conversion (APC) Powerchute software, the
NoSerialMice:COMx option is added to the Boot.ini file as follows:
multi(0)disk(0)rdisk(0)partition(1)\WINNT35="Windows NT Workstation
Version 3.51" /NoSerialMice:COMx
multi(0)disk(0)rdisk(0)partition(1)\WINNT35="Windows NT Workstation
Version 3.51 [VGA mode]" /basevideo /sos /NoSerialMice:COMx
CAUSE
The COMx device is set according to the COMx option that is selected
during APC setup. If this COMx device is set incorrectly, or if it
is in conflict with a pointing device already using the COMx port, the
pointing device no longer functions due to an incorrect setting in
Boot.ini.
RESOLUTION
To correct this problem, modify the Boot.ini file as follows:
- On File Manager View menu, click By File Type and then click Show Hidden-System Files.
- Find Boot.ini in C:\ (or appropriate partition).
- On the File Manager menu, select Attributes and clear all file attributes.
- Edit the file using Notepad to contain the appropriate settings
according to the following information:
/NoSerialMice - Disables the detection of serial mice on all COM
ports.
/NoSerialMice:COMx - Disables the detection of serial mice on
COMx, where x is the number of the port.
/NoSerialMice:COMx,y,z - Disables the detection of serial mice on
COM x, COMy and COMz.
- Save and quit Notepad.
- Return the attribute permissions cleared in Step 3.
- Restart the computer.
