<title>Supported Devices Overview</title>

<para>This section contains additional information about what

devices may or may not be supported by &os;/&arch;.</para>
|
|
|
|
<para>Except for the PC chipset embedded &man.ata.4; controllers,
|
|
most should work out of the box. Eventually, all
|
|
&arch;-compatible ATA controllers are expected to be fully
|
|
supported. Refer to the following sections for various disk
|
|
controllers and their current status.</para>

|
|
<para>In general, <quote>PC standard</quote> serial ports
|
|
supported by the &man.sio.4; driver are expected to work on
|
|
Intel legacy machines, but not PA legacy machines. The reason
|
|
is that all devices on HP machines are memory-mapped and there
|
|
is <emphasis>no</emphasis> ISA device support other than the PCI
|
|
dictated VGA legacy.</para>
|
|
|
|
<para>In addition to &man.sio.4; devices, the following devices
|
|
fail on non-Intel legacy machines (but should work on boxes with
|
|
an Intel legacy) because their drivers make ISA-specific
|
|
assumptions that do not hold:</para>
