Hi at all , I hope somebody help me to solve this problem , i'm new in device driver developing and bios structure study. I try to fix the incompability on modern PC of old PCI/ISA soundcard gameport on Win7 64bit S.O. I saw that Acpi Table DSDT in my AMI Bios release 2.0 do not have control method for assign resource to "Device Gameport" at I/O port 0x201. My Question is : The action to fix this incompability is only to add a control method or i do anything else? Regards A
