This field is har dwir ed to 0.

Bit

10~31

These bits are hardwired to 0 to indicate the Memory space size that

the device requires.

A value is 0 after har dwar e r eset.

These bits is readable and writable. This field can be programmed

by BIOS to specify the base address.

Descr iption

The value is 0 after har dware r eset.

This field is readable and writeable.This bit is set to 1 if the device

requires the expansion ROM space, else it is set to 0. After the load-

ing of ROM size from EEPROM, the value is set 1 if the ROM size

is not equals to zero,

This field is har dwir ed to 0.

The value is 0 after har dware r eset.

This field is partitioned to two parts, one is for size and another is

for base address. Size field is hardwired to 0 dependent on ROM

size. Base Address field is read-write bits which can be allocated by

BIOS.
