			==Boot ROM usage==

			You can use the MXV11-B2 ROM chip set ([https://github.com/larsbrinkhoff/DECROMs 23-145E4-00 / 23-146E4-00]) to convert the MXV11-B into a boot module for [[QBUS]] [[PDP-11]]s capable of booting:
			* [[RL01]] / [[RL02]] (DL)
			* [[RX01]] / [[RX02]] (DX,DY)
			* [[TU58]] (DD)
			* [[TSV05]] (MS)
			* [[MSCP]] type Devices e.g. [[RD51]], [[RX50]] (DU)
			* [[DECnet]] via [[DPV11, [[DLV11-E]], [[DLV11-F]], [[DUV11]]

The '''MXV11-B Multifunction Option Module''' is a [[QBUS]] [[DEC card form factor|dual-height]] [[peripheral]] board ('''M7195'''), intended to allow the creation of complete systems in a minimal-sized QBUS [[backplane]]. It is very similar to the earlier [[MXV11-A Multifunction Option Module]], except that it is a [[QBUS#Variable address size|Q22]] device.

It contains two [[asynchronous serial line]]s (using the [[DL11 asynchronous serial line interface|DL11]] programming standard), an optional [[clock]], a block of [[main memory]], and some [[read-only memory|PROM]] for [[bootstrap]] purposes. The serial lines are connected via 10-pin [[Berg connector]] headers on the top edge of the card, using the standard [[DEC asynchronous serial line pinout]], and line 1 can be set to [[halt]] or boot the machine on a [[Asynchronous serial line#Break|break]].

The clock is program-compatible with the [[KW11-L Line Time Clock]], but it is not a [[line time clock]], since it cannot be driven from [[alternating current|AC]] wall power; it can be connected to 50Hz, 60Hz, or 800Hz clock signals from a divided-down 20MHz crystal which is also used to provide the clock to the serial lines.

The board contains 128Kbytes of [[Random Access Memory|RAM]]; it can hold a pair of 2, 4, 8 or 16KB ROMs.
