Bits

7–4

These

bits

are

reserved.

 

 

 

 

 

 

 

 

 

 

Bit

3

This

bit

provides

a

security

lock for the secured area of

 

 

RT/CMOS. If this bit is set to 1, the 8-byte power-on

 

 

 

password

is

locked

by

the

software. After

this

bit

is

set

 

 

by

POST,

it

can

be

cleared

only

by

turning

the

system

 

 

 

off.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Bit

2

This

bit

is

reserved.

 

 

 

 

 

 

 

 

 

 

 

 

Bit

1

This

bit

is used to enable the ‘addressA20 )

20’ signal

(

 

 

 

when

the

microprocessor

is

in

the real address mode. If

 

 

this bit is A20set cannotto0, be used in real mode

 

 

 

 

 

addressing. This

bit

is

set

 

to 0 during a system reset.

 

Bit

0

This

bit

provides an alternative method of resetting the

 

 

 

system microprocessor. This alternative method

 

 

 

 

 

supports

operating systems requiring faster operation

 

 

 

 

than that provided on the IBM Personal Computer AT.

 

 

 

 

Resetting the system microprocessor switches the

 

 

 

 

 

microprocessor from protected mode to real address

 

 

 

 

mode.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This

bit

is set to 0 by either a system reset or a write

 

 

operation. If

a

write

operation

changes

this bit from 0

to

 

 

1,

the

‘processor

reset’

signal

is

pulsed

after

the

reset

 

 

has occurred. While the reset is occurring, the latch

 

 

 

remains

set

so

 

that

POST

can

 

read

this

bit. If

the

bit

is

 

 

set

to

 

0, POST

assumes

that

the

system

was

just

 

 

 

 

 

powered

on. If the bit is

set to 1, POST assumes that

 

 

 

the

microprocessor

has

been

 

switched

from

protected

 

 

 

 

mode

to

real

mode.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If

bit

0 is used to reset

the system microprocessor to the

 

 

real

mode,

use

the

following

procedure:

 

 

 

 

 

1.Disable all maskable and nonmaskable interrupts.
