    We are trying to replace a BFEE module with a HFEE (due to availability) and whould like to keep the video controller into shutdown mode since not used.

    How can we control the PCI_VID_POWERDOWN# signal (comes out from CPLD) ?

    Is there available specification that describe the CPLD mapping into memory space and contol of output pins?

    We want to control the PCI_VID_POWERDOWN# pin from Linux and be able to script the video controller shutdown using "devmem" type commands.
    Please provide example if available.
