Sorry if this has been asked before, I couldn't find an answer relating to floppy controllers.

I know using an add-in IDE controller frees up some clock cycles on the CPU thus leading to more cycles for other things, but does the same translate for FDD controllers? I have the Adaptec AHA-1542CF and in addition to SCSI it has a FDD controller, I'm wondering if it's better to use the Adaptec, or the on-board FDD controller? I have both 3.5" + 5.25" floppy drives.

Thanks 😀

If it doesn't conflict with the motherboard FDDC I see no reason not to use it, or at least try and see if it makes a difference. I think on the 1542CF you can configure it so it doesn't conflict.

I/O, I/O,
It's off to disk I go,
With a bit and a byte
And a read and a write,
I/O, I/O
