ABSTRACT:
A computer system having: a central processing unit (CPU), having a system bus associated therewith, a first bus interface circuit (BIC) in circuit communication with the CPU and generating a peripheral bus, such as the MICRO CHANNEL bus, a floppy drive controller (FDC), and an Integrated Drive Electronics (IDE) hardfile (hard drive). The IDE hardfile is in electrical circuit communication with the peripheral bus via a second bus interface circuit. The second bus interface circuit includes a writable latch having at least two states and in circuit communication with the peripheral bus. The latch states are selectable by the CPU via the system bus. The second bus interface circuit also has an access control circuit in circuit communication with the peripheral bus, the system bus, and the latch for selectively allowing data transfers between the CPU and either the FDC or the IDE hard drive, depending on the state of the latch.
