this version include: - Support for version 2.x firmware (2.42 or later recommended). This means we are the only open-source driver supporting these adapters. This code has only been tested on a Digital KZPCA adapter in an Alpha system, but is believed to be correct. NOTE: EISA adapters are not yet supported. - Support the BIOS/Firmware initialisation handshake protocol. This allows the driver to bring the card up to operational state even if the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system). - A working command pasthrough interface. This allows a user-space configuration tool (under development) to issue arbitrary commands to the controller or to devices in the system.
