Attention

When changing your startup sequence, you must be extremely careful when doing write operations (such as copying, saving, or formatting). Your data or programs can be overwritten if you select the wrong drive.

For more information about the selectable drive-startup sequence, refer toThinkPadthe User's Guide.

Hardware Compatibility

The computer supports most of the interfaces used by the IBM Personal Computer AT* and the Personal System/2* (PS/2*)

products. In many cases, command and status organization of these interfaces are maintained.

The functional interfaces for the computer are compatible with the following:

Ÿ	The	Intel	8259	interrupt controllers	(edge	trigger mode).
Ÿ	The	Intel	8254	timers driven from	1.193	MHz (channels 0,	1, and
	2).

ŸThe Intel 8237 DMA controller-address/transfer counters, page

registers, and		status		fields only. The command and request
registers,	and	the	rotate and		mask functions, are not supported.
The mode	register		is	partially	supported.

Ÿ The NS16550 serial communications controller.

ŸThe Intel Pentium microprocessor (ThinkPador 560)

the Intel Pentium processor with the MMX technology (ThinkPad 560E).

ŸThe Intel 8086**, 8088**, 80286**, 80386**, and i486DX microprocessors.

Ÿ	The	Intel	8087**, 80287**, 80387** math coprocessors.
Ÿ	The	Intel	82077AA** diskette	drive controller.
Ÿ	The	keyboard interface at		addresses hex 0060 and hex 0064.

ŸDisplay modes supported by the IBM Monochrome Display and
