Disabling a card to free up a virtual slot.

Hi all,

Somehow this posted without the message.

I'd like to be able to assign my CFFA3000 virtual Disk ][ to the same slot as my real floppy drive controller. That way I could switch betweem the two without opening up the computer. At first I thought to cut the Ground trace on the card, and wire in a switch to turn off the whole thing. However, I am wondering if it is possible to disable the physical card with a machine language routine?

Is anyone familiar with doing something like this? RamWorks appears to come with a SLOTCHANGER program that can reassign a slot for it's emulated RamDrive.

I've seen hacks where people

I've seen hacks where people made a switch to exchange slot numbers, so for example you could put one in slot 6 and one in slot 7 and flip a switch to swap them around. It shouldn't be too hard with a DPDT and planning it out on paper.

I think you only have to swap one wire...probably 41 /DEVSEL but you will have to break the connection from the board to the slot and intercept it with your switch.

In my case, I need to assign

In my case, I need to assign a virtual device to the same slot as a real one, and toggle between them. Could I add the switch to Devsel to disable the physical card? I would sooner modify the disk controller than the mobo.

Just trying to figure out if disabling Devsel or IOsel is the right move.
