Specifications

The first two numbers are specified in units of kB. The default buf_size is 32kB, and the maximum size
that can be specified is a ridiculous 16384kB. The write_threshold is the value at which the buffer is
committed to tape, with a default value of 30kB. The maximum number of buffers varies with the number of
drives detected, and has a default of two. An example usage would be:
st=32,30,2
Full details can be found in the README.st file that is in the scsi directory of the kernel source tree.
6.2 Arguments for SCSI Host Adapter Drivers
These are arguments for low level SCSI host device drivers, and as such are typically only used by those that
compile their own kernel with the SCSI driver built in. These people are advised to check the source for the
latest list of options that can be supplied to their driver.
