I have read some previous questions concerning the same problem, but haven't sucessfully installed the modem yet. I have a Supra Express 56K internal V.90 voice modem with no physical jumpers on the modem card. (PCI) I am currently using NT 4.0 w/ SP 1. I am using a Baby AT board and I believe there are only two COM ports (1 & 2). In my BIOS, the default IRQ and I/O base address for COM 1 is IRQ 4/3FxB (mouse is using COM 1), for COM 2 is IRQ3/2FxB. There is also an option called "Interal Modem Use IRQ": which I don't know what value to set to.
My questions are (Mouse is using COM 1 currently)
1) Should I let NT automatically detect my modem? Or should I use the "Have disk" option and installed the modem driver for NT? Everytime I installed using the "Have disk" option and used COM 2, NT will say the modem is current using COM 2 but is "Inactive" and "Unavailable".
2) What value should I set the "Modem use IRQ " in BIOS to? (I usually use 3)
3) Should I enable or disable Com 2? When I disable serial port 2 in my BIOS, then COM 2 is gone in NT.
4) I have installed PnpIsa , but didn't detect the modem
5) (Serial Port 2 is Enabled) I have tried to remove all ports and reboot again, everytime I do that, only Com 2 is available, then I set the address to 2FxB and IRQ to 3 : the same settings on the BIOS for serial port 2 and let NT reboot. Should I add more com ports such as 4 and 5?
6) I have used the NT Diagonistic tool and discovered that "Serial" is using IRQ 3 and 2FxB when the mouse is on COM
1 and if I switched my mouse to COM 2, "Serial" will be using IRQ 4, 3FxB : the settings mouse was using.
I have tried all these different methods, do they look reasonable and am I missing some critical steps?
Any help or advice would be wonderful!
