Abstract

When either a unique adapter 25 or a common function I/O adapter 50 (Fig. 1) is replaced because of an engineering design change, an upgrade to a new feature, or by the removal of a feature, the microcode in the computer system often times must also be changed to be compatible with that level of I/O adapter. This means that the microprograms that reside on the disk, diskette, etc., would not be compatible with different I/O adapters. This results in having different diskettes and/or different programs on the disk, tape, etc., for each level of I/O adapter.
