+ * The VGA adapter uses two I/O port blocks. One of these blocks, the CRT
+ * controller registers, can be located either at 0x3B0 or at 0x3D0 in I/O
+ * port space. This allows compatibility with the monochrome adapter, which
+ * has the CRT controller registers at 0x3B0.
+ *
+ * It is assumed that compatibility with the monochrome adapter is not of
+ * interest anymore. As such, the CRT controller can be located at 0x3D0 in
+ * I/O port space unconditionally. This means that the 2 I/O blocks are
+ * always adjacent and can therefore be treated as a single logical I/O port
+ * range. In practical terms: there only has to be a single tag and handle
+ * to access all registers.
+ *
+ * The following definitions are taken from or inspired by:
+ *   Programmer's Guide to the EGA, VGA, and Super VGA Cards -- 3rd ed.,
