9Changing the Operating System
The GM56PCI-SM Modem software is the same for Windows 95 and Windows 98. If the modem
is installed on Windows 95 and you upgrade to Windows 98, the GM56PCI-SM will continue to
function as before. No new drivers are required.
However, if you change from Windows 95 or Windows 98 to Windows NT you must get a new set
of drivers for that operating system. The GM56PCI-SM modem software for Windows 9x will not
work under Windows NT. Contact your direct modem vendor or PC supplier for drivers, or visit
their Web sites.
10 Using the GM56PCI-SM Modem
DOS-Based Applications and Games
Importnt: DOS box support is disabled after the GM56PCI-SM is installed. After install is
complete, you must enable it via the Advanced tab in the GM56PCI-SM Control Panel application
(Start->Settings->Control Panel, then double-click the GM56PCI-SM Modem icon). Make sure
the DOS box check box is checked. If not, click it to check it, exit the GM56PCI-SM Control
Panel application and restart the computer. You must restart the computer to complete DOS box
enabling.
The GM56PCI-SM can be used by DOS applications only through a Windows 95/98 DOS box.
Win 9x DOS box support is achieved by virtualizing the standard I/O and IRQ assigned to a COM
port. This means that the GM56PCI-SM drivers capture and redirect all I/O to/from the standard
I/O address for the COM port to which it assigned. In simpler terms, you tell the application the
COM port that the GM56PCI-SM modem is installed on, and then use all the standard I/O and
IRQ settings. Standard I/O addresses and IRQs for COM Ports 1-4 are as follows:
