Hi,
I have an Adaptec 1542B ISA card, which works fine as a primary FDC (jumpered for 0x3F0), but I can't get Linux to see it as a secondary FDC (jumpered for 0x370)
I've read the fdutils documentation; specifically the sections on floppy=two_fdc and floppy=drive,type,cmos, but I'm not clear. It doesn't explain how to express drive; is it a single digit ? Is if fdx, where x is a single digit ?
Based on the following setup :
Primary FDC (on motherboard) - 2.88Mb 3.5" FDD, and 360K 5.25" FDD
Secondary FDC (AHA-1542B) - 1200K 5.25" FDD
....could somebody shed some light on the parameters I need for the "modprobe floppy" command ?
Thanks in advance

Drives on the second FDC start being numbered starting at 4.
/dev/fd4 = first drive on second FDC /dev/fd5 = second drive on second FDC.

These are the same as the boot time parameters (described in /usr/src/linux/Dcoumentation/blockdev/floppy.txt)
