A rewrite was +long overdue, and the current version addresses the following concerns: + + (1) extensive kernel changes between 2.4 and 2.6. + (2) deprecated PCMCIA support outside the kernel. + +All the USE_BIOS code has been ripped out. It was never used, and could +not have worked anyway. The USE_DMA code is likewise gone. Many thanks +to YOKOTA Hiroshi (nsp_cs driver) and David Hinds (qlogic_cs driver) for +the code fragments I shamelessly adapted for this work. Thanks also to +Christoph Hellwig for his patient tutelage while I stumbled about. + +The Symbios Logic 53c500 chip was used in the "newer" (circa 1997) version +of the New Media Bus Toaster PCMCIA SCSI controller. Presumably there are +other products using this chip, but I've never laid eyes (much less hands) +on one. + +Through the years, there have been a number of downloads of the pcmcia-cs +version of this driver, and I guess it worked for those users. It worked +for Tom Corner, and it works for me. Your mileage will probably vary. + +--Bob Tracy (rct@frus.com) -- cgit v1.2.3
