Access to pci-e card after bios update

Products & Technology ODYSSEY Serials

In the meantime i tried two different ones.

  1. New Digitus DS-30020-1 Rev. 2 with AX99100 chip. I have w10 driver and it works fine in your board. Is not enabled in mint 19 as lspci shows.

  2. An older EXSYS EX44092-2 with OXmPCI952 chip.
    Lspci shows normal registers (0xE060) but nothing in the high range (normal is plus 0x0400 higher). This one was working in normal pc in EPP mode for cnc milling. Not working in w10 (not needed)

After googling as fare as i can understand it is a functionality of the bios to help linux to activate the epp part of the chip…
Mike and thx in advance for your help.
