Not really. Only two of the switches are real toggles: one selects
whether hardware compression defaults to on or off, and the other one
selects whether the hardware compression might be changed with a SCSI
command.
The remaining 6 switches must be taken as a whole, in that they simply
select one out of 64 ``quirk behaviours'' for the firmware. That's
why there is this ``uses this for that'' description, it merely works
around known idiosyncrasies of the various operating system drivers.

Well, QIC-150 cartridge prices are as low as 0 for me. :)
