# HG changeset patch # User Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx> # Date 1310493177 14400 # Node ID d42a0c7903e6828cccfc8b9fc7d15ba578019674 # Parent 841e8a1304e707bb9f077d014fb59d46133fbeae doc: Update the com1,com2 section with pci and amt options. The "xen: Automatically find serial port on PCI/PCIe and AMT devices." provides the functionality to probe for the I/O base using the "pci" and "amt" option. Update the documentation with this fact.
