|
|
This structure contains the hints for where we should look for the
|
|
host adapter. If you want to change where we search or reduce the
|
|
places we search to avoid confusing some other device, either
|
|
specify explicit addresses in the kernel config file (preferred)
|
|
or change this array.
|
|
|
|
If the kernel config file has multiple ? entries, the probe routines
|
|
will use this table multiple times and will eliminate each failed
|
|
entry that probe tries.
|
|
|
|
WARNING: The number of controller entries for this driver in config
|
|
must be less than or equal to the number of hints if hints are used.
|
|
|
|
If you add entries to the table, add them immediately before
|
|
the -1 end-of-table marker. The values already present are
|
|
the ones used by Creative Labs boards and those of a few
|
|
other vendors.
|
|
|
|
Each additional entry increases the boot time by four seconds,
|
|
and can increase the chance of accessing some other device.
|
|
Therefore, the list should be kept to a minimum. Once the
|
|
devices have been correctly located, the kernel should be
|
|
configured so that it looks only at the correct location from
|
|
that point on.
|
|
|
|
Be sure to search devices located below 0x3ff BEFORE scanning
|
|
higher locations. Some boards don't decode all I/O address lines,
|
|
so 0x230 and 0x630 appear identical.
