&arch-title; machines are generally self-configuring and do not require firmware configuration. However, you should make sure that you have the appropriate ROM and system patches. On the Macintosh, MacOS version >= 7.1 is recommended because version 7.0.1 contains a bug in the video drivers preventing the boot loader from deactivating the video interrupts, resulting in a boot hang. On the BVM VMEbus systems you should make sure you are using BVMBug revision G or higher boot ROMs. The BVMBug boot ROMs do not come as standard on the BVM systems but are available from BVM on request free of charge.
