manybodies are saying that sometimes floppy is disapeared on DP264.
It's sometimes detected sometimes doesn't.
Certain board always failed to detect floppy drive.
So I've look at the problem but I couldn't find the reason
but I've found a work around for this problem.
If I put the controller's state to normal before floppy driver
reset the controller then it works fine.
SRM doesn't detect or initialize floppy controller until it's really used
and I think It makes the problem.
I'm not used to floppy so I need confirmation from experts.
Is this safe?
Here's the patch.
