Unfortunately, the module is not smart enough to infer
existence of a
second FDC from the existence
of a drive numbered 4, so both options (two_fdc and
4,4,cmos) need to be
given.
I have tried with and without the two_fdc option.
But I thought from the Documentation, the kernel module didn't need the
two_fdc parameter if you were making a cmos declaration for a 4th (or
higher) drive......
floppy=two_fdc
<http://www.mjmwired.net/kernel/Documentation/floppy.txt#74>floppy=<address>,two_fdc
<http://www.mjmwired.net/kernel/Documentation/floppy.txt#75>Tells the
floppy driver that you have two floppy controllers.
<http://www.mjmwired.net/kernel/Documentation/floppy.txt#76>The
second floppy controller is assumed to be at <address>.
<http://www.mjmwired.net/kernel/Documentation/floppy.txt#77>This
option is not needed if the second controller is at address
<http://www.mjmwired.net/kernel/Documentation/floppy.txt#78>0x370,
and if you use the 'cmos' option.
Thanks for the response - will try giving the 1542b its own IRQ and DMA when
I get home
