                     15: .I Ldpcs
                     16: loads microcode
                     17: from

                     21: the hardware ID register is checked
                     22: to see that the system is an 11/750
                     23: and that its base microcode revision level
                     24: is appropriately high;
                     25: the
                     26: .B -f

                     41: .PP
                     42: The patch file consists of

                     45: Each patch bit represents a 20-bit microcode word;
                     46: the patches themselves are 20-bit words
                     47: packed together.
                     48: The format is the same as that distributed by DEC.
