* A rewrite of the pcmcia-cs add-on driver for newer (circa 1997)
5
* New Media Bus Toaster PCMCIA SCSI cards using the Symbios Logic
6
* 53c500 controller: intended for use with 2.6 and later kernels.
7
* The pcmcia-cs add-on version of this driver is not supported
8
* beyond 2.4. It consisted of three files with history/copyright
