+Generic 4 drives/port support

+  Certain older chipsets, including the Tekram 690CD, use a
+  single set of I/O ports at 0x1f0 to control up to four drives,

 Console on serial port
 CONFIG_SERIAL_CONSOLE
-  If you enable this option, all kernel messages will be sent to the
-  device /dev/ttyS0 which corresponds to a serial port; this could be
-  useful if you attached a terminal or printer to that port. (You can
-  change the number of the serial port used from 0 to something else
-  by setting the variable CONFIG_SERIAL_CONSOLE_PORT.) You can use
-  this option in combination with the option "Console on virtual
-  terminal" above, in which case you get the output on both the serial
-  port and on your display. Most people say N here so that they can
-  use the serial port for modem, mouse or some other device.
+  If you enable this option, it is possible to use a serial port as the
+  console. By default still the virtual console will be used at the
+  system console but you can alter that using a kernel command line
+  option. If you don't have a VGA card installed the kernel will
+  automatically use /dev/ttyS0 as system console if this option is
+  enabled.
