The IBM Personal System/2 Hardware Interface Technical Reference
describes devices common | to | the PS/2* | system | family. | |
The IBM ThinkPad 560/560E computer (hereafter | called | the | 560, | ||
ThinkPad computer, orcomputer) | is | a | 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 15H, function code (AH)=23H, (AL)=10H, returns (AL)=0EH for the 560/560E.
The system microprocessor contains an internal cache and cache controller.
