Latest Atari compatible hardware like Medusa, Hades or Milan have PCI bus to improve the system extensions. However, specific drivers are required for each PCI card. Currently the nfpci driver only allows you to list host PCI devices (a good start!). Just install 'nfpci.prg' in the AUTO folder to run it at your system's boot. This program is TOS resident, so it must be run before MiNT kernel.
