Changeset 10550:dbbee17f23e1 --------------------------- x86: pc: Put a stub IO device at port 0xed which the kernel can use for delays. There was already a stub device at 0x80, the port traditionally used for an IO delay. 0x80 is also the port used for POST codes sent by firmware, and that may have prompted adding this port as a second option.
