Interest in a driver for PCMCIA Bus toaster (New Media) with advansys chip set?

[Stefan Schmitt]

Hallo,

the card is labelled PS: 404-15-02A. As much as I could see, there
is no linux driver available.

        Product Name:   PCMCIA Bus Toaster SCSI Adapter
        Identification: manf_id: 0x10cd card_id: 0x0001
                 function: 8 (SCSI)
                 prod_id(1): "PCMCIA Bus Toaster" (0x590031a6)
                 prod_id(2): "SCSI Adapter" (0x96269fcd)

I have an initial version of driver code (for the 2.6 kernel). I could send 
the code to someone more experienced if there is interest.

Cheers,
Stefan

Is it (in any way) similar to the PCI/ISA advansys chipsets?  (see
drivers/scsi/advansys.c)  If so, we should probably merge the drivers.

the code is sort of similar, so maybe this could be done. Here are the main 
differences:

 (1) the PCMCIA card uses memory mapped IO in contrast to the PCI/ISA drivers
 (2) the PCMCIA card does not do DMA [at least not on my computer] so there is 
an extra part in the driver for doing PIO.

I also experienced some difficulties with a few other parts of the PCI/ISA 
driver code and this PCMCIA board. The microcode can be shared in any case.

I suspect this will turn out as it did for me when I tried to do
something similar with the Symbios Logic 53c500 version of the New Media
Bus Toaster :-).  Since you presumably have access to the card, you're in
the best position to do further development and testing on the driver.

Maybe the other one or two people running Linux who have one of these
beasts will come forward and volunteer to help with the testing, but the
53c500 version was supposedly newer (circa 1997), so the odds aren't
good.  Even so, I'd say please submit the driver.  I wouldn't trade my
experience with the driver development process for anything: it was fun
and I learned a lot.

In case someone is interested: the code is available here:
