Chapter 3
Address Space
The design of the hardware for the system bus (the XMI) and for the
optional VAXBI bus affects addressing. The XMI card cage has its 14
slots permanently assigned to specific address locations. For the Model
500, no modules that require I/O cables can be installed in the middle
four slots (slots 6 through 9). The VAXBI bus consists of two VAXBI card
cages that are physically fastened together and logically connected as one
12-slot VAXBI bus. For more information on VAXBI node addressing, see
Section 3.2.
