    I attached an IOMEGA parallel zip drive to the parallel port
    and insmod-ed ppa . I wasn't able to mount the thing (not
    going to use it, so am not worried about it), but could tell
    from the lines in /var/log/messages that it was being recognized.
    Hence, I think the problems I am having with the Trakker
    is a result of something other than parport and parport_pc.

    cat /proc/parport/0/irq gives "7".

    cat /proc/parport/0/hardware gives :
    base: 0x378
    irq: 7
    dma: none
    modes: SPP
    (want to change to EPP, but forgot which function key brings
    up the bios settings on this Aptiva 486DX ...)

     
    /dev/ftape is linked to rft0
    is this correct?

    I used ftape's default lines for Trakker in MCONFIG.
    Is this correct?
     
    TRAKKER_DEV=0
    FDC_OPT += -DCONFIG_FT_FDC_PARPORT_$(TRAKKER_DEV)=-1 \
                    -DCONFIG_FT_PAR_$(TRAKKER_DEV)=1 \
                    -DCONFIG_FT_TRAKKER_$(TRAKKER_DEV)=1

    After testing the zip drive, switching back to the
    tape drive (unplugging and plugging in the latter),
    I got different error messages in /var/log/messages .
    I thought it might work, but no such luck.

    Any advice appreciated.
