In general, you want to load the ispfw module or compile it into your
kernel.  The driver was tested with the firmware included in the module,
and may not work as well (or at all) with a different version.

If you know what changed between the firmware version compiled into the
ispfw module and the one you want to run, you can make any necessary driver
modifications.

You need to compile your kernel with:

options		ISP_TARGET_MODE=1

Otherwise you won't get target mode functionality in the isp(4) driver.

If I recall correctly, the firmware that is loaded on boot is loaded into
RAM on the card, not flashed.  I don't think it affects what is actually
flashed onto the board.

So that really is what you want to do.

Also, just FYI, in past testing with 4Gb Qlogic boards I was limited to
256MB/sec in each direction when I tried them out.  I haven't seen the same
limitation with the 8Gb boards.

It has been a few years since I tried out target mode with a 4Gb board, but
keep an eye out for that once you get it running.
