<question id="aci0-illegal-cable">
<para>When I boot my system, I get the error <errorname>ahc0:
illegal cable configuration</errorname>. My cabling is
correct. What is going on?</para>
</question>
<answer>
<para>Your motherboard lacks the external logic to support
automatic termination. Switch your SCSI BIOS to specify the
correct termination for your configuration rather than
automatic termination. The &man.ahc.4; driver cannot
determine if the external logic for cable detection (and
thus auto-termination) is available. The driver simply
assumes that this support must exist if the configuration
contained in the serial EEPROM is set to <quote>automatic
termination</quote>. Without the external cable detection
logic the driver will often configure termination
incorrectly, which can compromise the reliability of the
SCSI bus.</para>
