 OpenBSD/MACHINE requires the SRM console.  Some alphas come with
 the AlphaBIOS (also known as the ARC firmware on older machines) instead;
 this is what Windows NT uses. It is fairly simple to replace the AlphaBIOS

+EISA configuration:
+
+    A few MACHINE systems support EISA devices. However, the SRM firmware
+    has only a very limited knowledge of EISA devices and is not able to

+    Every time an EISA board is added to or removed from the system, the
+    EISA Configuration Utility needs to be run from a floppy disk using the

+    be provided with EISA-capable systems; this disk will be updated with
+    the current configuration every time it is run, and needs to be
+    writeable. ECU disks should not be shared between systems.
