Yup, had that happen on one of my machines with a 100 MBit/s NIC wired to
a GBit switch. It dropped all the way down to 10 MBit/s half-duplex and
still lost packets at a hilarious rate - because the cable had gone bad.
After replacing the cable it was back to 100 MBit/s.
But the point is: the GBit switch followed along all the way down to
10 MBit/s half-duplex "hey, if that's all you can do, fine", just as
the spec said it should.
Kind regards,

It is not unheard-of for classic PCs -- even ISAbus ones -- to have
10Mbps ethernet. Most, if not all, 100Mbps ethernet ports will fall
back to that.
Not only that, but all correctly implemented GigE devices will fall back not just to 100
but also to 10 Mb/s. That's part of standards conformance, and from what I can tell
even low cost devices like D-Link or Netgear do this. Yes, including half duplex mode.
