<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.
