Bits
Name
Description
Word
AH,
15:14
Signature
The Signature field is a signature of 01b, indicating to the 82559 that there is a
valid EEPROM present. If the Signature field is not 01b, the other bits are
ignored and the default values are used.
Word
AH, 13
ID
The ID bit indicates how the Subsystem ID and Subsystem Vendor ID fields are
used as described in
Section 8.1.12, “PCI Subsystem Vendor ID and
Subsystem ID Registers” on page 61
. Default value is 0b.
Word
AH, 12
Reserved
This bit is reserved and should be set to 0b.
Word
AH, 11
Boot Disable
The Boot Disable bit disables the Expansion ROM Base Address Register (PCI
Configuration space, offset 30H) when it is set. Default value is 0b.
Word
AH,
10:8
Revision ID
These three bits are used as the three least significant bits of the device
revision, if bits 15, 14, and 13 equal 011b and the ID was set as described in
Section 8.1.12, “PCI Subsystem Vendor ID and Subsystem ID Registers” on
page 61
. The default value depends on the silicon revision (for example, the
82559 C-Step’s Revision ID is 09h).
Word
AH, 7
82559 B-step
This bit is reserved and should be set to 1b.
82559 C-step
Alternate ID
This bit is used in conjunction with the Signature field and the ID bit to help
define the Device ID. When bit 7 equals 1b, the Device ID is 1229H and the
device is compatible to previous steppings of the 82559. When bit 7 equals 0b,
the LAN function reports a Device ID of 1029H and the device is not compatible
with the 82559. Details regarding the 82559 ID programming are described in
Section 8.1.12, “PCI Subsystem Vendor ID and Subsystem ID Registers” on
page 61
