firmware

  • There are several different firmwares for different hardware. so you have to pick the right one, download, rename and put it into the right place... Normally this should be /lib/firmware. However some distributions put firmware in a different place.
  • miniPCI / PCMCIA don't forget to rename it: isl3886

  • USB 1st generation rename it to: isl3890usb

  • USB 2nd generation rename it to: isl3887usb_bare

    additionally, firmwares can be extracted from windows drivers fwextract3
