Chapter 2 51
NOTE As stated earlier, HP recommends you to always use the A6829A’s
maximum bus width (16 bits), unless you have Narrow (8-bit) devices on
the bus and you are experiencing problems with the connection.
If you decrease the maximum bus width value (16 bits) when the
transfer rate (MT/sec) is set to 80 or 160, the following message is

decrease the corresponding bus width value.
