Intel^® 82598EB 10 GbE Controller - Hardware EEPROM Sections
3.4.3.3.9 PCIe Control – Offset 8 – Sub-System ID
If the load sub-system IDs in offset 0x7 of this section is set, this word is read in to initialize the sub-
system ID. The default value is 0x0.
3.4.3.3.10 PCIe Control – Offset 9 – Sub-System Vendor ID
If the load sub-system IDs in offset 0x7 of this section is set, this word is read in to initialize the sub-
system vendor ID. The default value is 0x8086.
3.4.3.3.11 PCIe Control – Offset 10 – Dummy Device ID
If the load vendor/device IDs in offset 0x7 of this section is set, this word is read in to initialize the device ID of the
dummy device in this function (if enabled). The default value is 0x10A6.
3.4.3.3.12 PCIe Control – Offset 11 – Device Revision ID
Bit
7:0
Name
DEVREVID
Default
Description
0x0
Device Rev ID
The actual device revision ID is the EEPROM value XORed with the hardware value
(0x00 for 82598 A-0).
3.4.3.4 EEPROM PCIe Configuration Space 0/1 Sections
Word 0x7 points on the PCIe configuration space defaults of function 0 while word 0x8 points to
function 1 defaults. Both sections are loaded at the de-assertion of LAN_PWR_GOOD, internal power on
reset, and a PCIe in-band reset. In addition, function 0 defaults are loaded after the de-assertion of
PCIe config 0 reset; function 1 defaults are loaded after the de-assertion of PCIe config 1 reset.
The structure of both sections is identical as listed in the following table:
Offset
0x1
0x2

3.4.3.4.1
3.4.3.4.2
3.4.3.4.3
3.4.3.4.1 PCIe Configuration Space 0/1 – Section Length
The section length word contains the length of the section in words. Note that the sections length does
not contain the section length word itself.
