Table 58. 24-bit OUI Identification Number
Table 59. MDI Identification Registers 2 and 3: PHY ID Encoding
The revision number is a 4-bit value assigned by the manufacturer identifying the PHY revision
number. The Intel devices use revision numbers “0000” through “0100.” The Intel 82558 has a
revision ID number of 0000b, and the 82559, 0100b.
The map below shows how the these three numbers (OUI, model and revision numbers) are
mapped into the MDI registers.
The PHY identification register values are as follows:
Auto-Negotiation Advertisement Register: Register 4
This register contains the advertisement ability of the PHY. It is used by software to determine the
highest common denominator technology after the auto-negotiation process has finished. Any
changes to this register prior to auto-negotiation must be followed by setting the Renegotiate bit in
the Command register.

Description
Next page is not supported and this bit should be
set to 0b.
This bit position in the transmitted code word is
used to indicate an acknowledge. It is set only by
the auto-negotiation logic after receiving three
consecutive and matching code words from the link
partner.
This bit indicates remote fault in the local station. It
may be set by management to indicate the remote
fault condition of the partner.
These bits are reserved.
This bit indicates that Pause is supported by the
local node.
This field indicates that 100BASE-T4 is supported
by the local node.
This indicates that 100BASE-TX full duplex is
supported by the local node.
This bit indicates that 100BASE-TX is supported by
the local node.
