+Read the Boot Initiator Mailbox in hex dump or in text mode.
+
+By default the whole mailbox is read. If block number is specified,
+that particular block is read. For block 0 or when the whole
+mailbox is read, the Boot Initiator IANA Enterprise Number and
+the corresponding enterprise name are printed.

+
+Write the specified <block> or the entire Boot Initiator Mailbox in text mode.
+It is required to specify a decimal IANA Enterprise Number recognized
+by the boot initiator on the target system. Refer to your target system
+manufacturer for details. The rest of the arguments are a text string.
+
+When single block write is requested, the total length of <data> may not
+exceed 13 bytes for block 0, or 16 bytes otherwise.
