COM Port and IRQ Conflicts
If you have isolated the problem to an IRQ or COM port conflict, refer to the following sections for
resolving IRQ and COM port conflicts in Windows 3.1x, Windows 95, Windows 98, or
WindowsNT.
Windows 3.1x
To look for COM port or IRQ conflicts in Windows 3.1x, select File | Run in Program Manager,
type MSD, and click Enter. Then select Mouse, COM Ports, and IRQ Status and note the
addresses and IRQs that are in use. If you find an IRQ conflict, note which IRQs are not being
used, then change one of the conflicting devices to use one of the unused IRQs. If you find an
address conflict, change the address of one of the conflicting devices.
To change a port address or IRQ in Windows 3.1x, double-click the Control Panel icon, then the
Ports icon. Click on the port you want to change, click Settings, click Advanced, and select the
new port address and/or interrupt. If you wish to use COM3 or COM4, note that COM3 shares
an IRQ with COM1, as does COM4 with COM2, so you should change their IRQs to unused
ones, if possible.
Windows 95/98
Windows 95/98 provides a complete "Plug n' Play" System that will automatically recognize and
configure most PC Cards.
As Multifunction PC Cards put a heavy demand on a system's resources, please resolve all
system conflicts, errors, and Windows 95 issues before installing the MT5634ZLX/E.
Windows NT 3.51 and NT 4.0
Windows NT provides support for PC Card (PCMCIA) compatibile systems. Do not run any of the
MT5634ZLX/E install programs as they are unnecessary for the NT environment. Multifunction
PC Cards put a heavy demand on a system's resources. Please resolve all system conflicts,
errors, and Windows NT issues before installing the MT5634ZLX/E.
Note: running Windows NT 4.0 with Service Pack 1 may cause some portable PCs to hang up
on Shutdown or Restart. If this occurs, please update to Service Pack 3 (or higher).
