Thanks for posting to the forum. I'll do some digging, however from what I can tell thus far, the default value is still what we use as default in our retail devices. When a LOM (LAN On Motherboard) is placed on a motherboard, the system manufacturer usually modifies it for thier needs, including any BIOS workarounds.
If memory serves, this issue was BIOS related and the change in the EEPROM was done by some server manufactures as a workaround. However I will go do some research and double check.
