98 PCA-6157/6157L User's Manual
The following three options affect the amount of memory used by
the driver. For information on how memory is allocated by the
driver, and to get an approximate feel for the amount of memory
which may be saved by invoking these parameters, refer to
Memory Allocation under Important Additional Information at the
end of this section.
Using the Maximum Host Adapters Option
Command line option: max_hbas=<option>
Default value: 8
Valid options: 1-8
Function: Specify the maximum number of Host
Bus Adapters to support.
Possible Impact: If number is reduced, may allow for
reduction in memory used by the driver.
Applicable Versions: 3.04.00 and higher
This parameter may be used to optimize the use of dynamically
allocated memory by the driver. If less than 8 NCR based PCI host
adapters, including any on board (built in to) the motherboard, are
being used, this parameter will allow for a reduction in the total
memory being used for the driver.
Using the Maximum SCSI IDs Option
Command line option: max id=<option>
Default value: 32
Valid options: 8-32
Function: Specify the maximum number of SCSI
IDs each host adapter board should
support.
Possible Impact: If number is reduced, may allow for
reduction in memory used by the driver.
Applicable Versions: 3.04.00 and higher
