hm2_pci is a device driver that interfaces Mesa’s PCI and PC-104/Plus based Anything I/O boards (with the HostMot2 firmware) to the LinuxCNC HAL.
The supported boards are: the 5i20, 5i22, and 5i23 (all on PCI); the 4i65 and 4i68 (on PC-104/Plus), and the 3x20 (on PCI Express, probably using a 6i68 or 7i68 carrier card).
The driver programs the board’s FPGA with firmware when it registers the board with the hostmot2 driver. The firmware to load is specified in the config modparam, as described in the hostmot2(9) manpage, in the config modparam section.
