I built a sydtem using this motherboard ,I had on problem bringing the system up and installing win2000 all the drivers loaded with on problem (video,sound card,modem)
when tried to use the modem I'm getting a message
unable to open port.I went into system and tried to change the basic config I still could not open the port .I added another port
using add new hardware but that port could not be open, out of four com ports only com port1 is working.I need help on how to open com ports. thanks

I guess you had _no_ problem, not _on_ problem installing the OS and drivers?

Why no COM port access for the modem? Simple, the modem is not a legacy serial device on a COM port, it's a PCI device integrated into the onboard sound unit. Access goes through the PCI bus, not over a legacy ISA bus COM port.

The modem driver installs a software emulation of an extra COM port to make old software happy that still thinks modems are accessed through COM ports. They're not - in Windows, modems are accessed through their respective modem driver, not a COM port driver. Not that Microsoft has gotten that right in everything that ships with Windows, e.g. HyperTerminal still can't use those :-(
