Is it possible to activate(enable) and deactivate(disable) pci cards like soundblaster cards by code?
what i want to do is to have up to 6 Soundblaster PCI cards installed but only use 2 at the time. 4 must be deactivated. but i want to be able to choose what card to be enabled.

I don't know the answer, but I would probably start looking at the SetaAPI set of functions, maybe you can do something with those:

Perhaps the following example helps / works:
Code: Select all
EnableExplicit
Define *F1, *F2, *F3
Define devhandle.l, id.s
OpenLibrary(1,"setupapi.dll")
*F1 = GetFunction(1, "CM_Locate_DevNodeA")
*F2 = GetFunction(1, "CM_Disable_DevNode")
*F3 = GetFunction(1, "CM_Enable_DevNode")
;look in registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum
;to find Identifiers for PCI/USB ... Devices
id.s = "PCI\VEN_1022&DEV_9609&SUBSYS_00000000&REV_00\3&267a616a&0&50" ;sample usb wlan
CallFunctionFast(*F1, @devhandle, @id, 0)
;Debug CallFunctionFast(*F2 ,devhandle, 0) ;disable device
;Debug CallFunctionFast(*F3 ,devhandle, 0) ;enable device
CloseLibrary(1)

I don't find right ID String to use.
id.s = "PCI\VEN_1022&DEV_9609&SUBSYS_00000000&REV_00\3&267a616a&0&50"
in my registry i don't have \3&267a616a&0&50 or smiliar to this.
Only PCI\VEN... 4-5 lines and i tryed all combinations but nothing helps.

OK. I thought it was clear that you are looking for "Sound Blaster" or similar in the branch "PCI".
Main point it works now.
