      <title>ISA legacy functions</title>

      <para>

	On older kernels (2.2 and earlier) the ISA bus could be read or

	written with these functions and without ioremap being used. This is

	no longer true in Linux 2.4. A set of equivalent functions exist for

	easy legacy driver porting. The functions available are prefixed

	with 'isa_' and are <function>isa_readb</function>,

	<function>isa_writeb</function>, <function>isa_readw</function>, 

	<function>isa_writew</function>, <function>isa_readl</function>,

	<function>isa_writel</function>, <function>isa_memcpy_fromio</function>

	and <function>isa_memcpy_toio</function>

      </para>

      <para>

	These functions should not be used in new drivers, and will

	eventually be going away.
