I have just installed FreeBSD 2.0, and I have has some problems getting
a couple of parts working:

  + I don't seem to have a device for any serial ports, so I can't get the
    mouse working, so I can't get X working...  I have the mouse on COM2:,
    a 16550 based serial port at the standard address
  + I am using a 1GB enhanced IDE hard disk.  The disk runs as 525 cylinders
    with 64 heads under dos, but FreeBSD doesn't support more than 16 heads
    so it has to run as 2100 cylinders with 16 heads.  FreeBSD can't boot
    past 1024 cylinders, and DOS just plain won't read past it, so basically
    I have to re-write the partition table to a different geometry every time
    I want to switch between DOS and FreeBSD.  Is there any way around this?
