Attention
The term Reserved describes certain signals, bits, and registers
that should not be changed. Use of reserved areas can cause
compatibility problems, loss of data, or permanent damage to the
hardware. When the contents of a register are changed, the
state of the reserved bits must be preserved. When possible,
read the register first and change only the bits that must be
changed.

Description
The IBM Personal System/2 Hardware Interface Technical Reference
describes devices common to the PS/2* AT-bus system family.
The IBM ThinkPad 560/560E computer (hereafter called the 560,
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 15H,
function code (AH)=23H, (AL)=10H, returns (AL)=0EH for the
560/560E.
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.
