    PCI Express Power Pin Toggle (on/off) function call ?

    I need to toggle the power pin(s) to the PCI Express Bus slot.

    I know the pin outs, I just don't know how to turn the power on or off. is there a function call, maybe in the HAL ?

    Here's some pin out info.

    Pin 1 Side B = +12v Side A is pulled low to indicate card inserted
    Pin 2 Side B & Side A = +12v
    Pin 3 Side B = Reserved Side A = +12v

    and it goes on pin 9 & 10 are + 3.3v etc.

    Thanks,
    Areal

    Are you sure they are programmable? I wouldn't be surprised if they are just hardwired to the voltage planes.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
