ADVANCE INFORMATION
ROM Code: Need to turn off internal termination resistors in SERDES
The SERDES implementation in this device has internal termination resistors enabled by default. During PCIe boot, the ROM code does not disable these termination resistors, which results in reduced voltage swing of the PCIe reference clock, potentially less than the minimum limit defined for a PCIe reference clock. This can result in PCIe boot failure.
