Description The IBM Personal System/2 Hardware Interface Technical Reference describes devices common to the PS/2 AT-bus system family. The IBM ThinkPad 560Z computer (hereafter called the 560Z, ThinkPad computer, or computer) is a notebook-size computer that features the AT* bus architecture. Each computer supports one external diskette drive and one internal hard disk drive. Programs can distinguish the foregoing models of computers from other ThinkPad models by reading the system ID: Interrupt X'15', function code (AH)=X'23', (AL)=X'10', returns (AL)=X'37' for the 560Z. The system microprocessor contains an internal cache and cache controller. Figure 1-1 lists the model bytes, submodel bytes, and system clock speed of the system board.
