PCMCIA is ISA 16 bit.

WIN2000 and WINDOWS XP disable ISA to PCI IRQ routing and therefore the serial card will not work.

I went into the regedit and added the necessary line to change that, but it still wont work.    I am sending it back . 

 

thanks for the help

Actually there are 3 lines and you may need to remove the hardware from the device manager in safe mode. Also you may have to disable the onboard serial if you have one.

 

Enable ISA IRQ Routing.

Then plug in the card and Detect it etc.

Win2000 SP1 AND XP SP1 etc and up DISABLE ISA IRQ

This makes it so the card WILL NOT WORK.

This symptom may occur with 16 Bit Non Cardbus PCMCIA adaptors.

 

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Pcmcia\Parameters]
"SoundsEnabled"=dword:00000001
"IsaIrqRescanComplete"=dword:00000000
"DisableIsaToPciRouting"=dword:00000000
