For some reason my F-12 system is not seeing my floppy disk controller at boot time. If I manually run "modprobe floppy" the controller is recognized ("FDC 0 is a post-1991 82077") and the drive works. Any ideas? F-11 finds the controller OK.
The solution turns out to be really simple. I did not have the floppy drive hooked up when I did the install. As a result, anaconda did not create the /etc/modprobe.d/floppy-pnp.conf file. With that file in place, F-12 sees the floppy drive just fine at boot. $ cat /etc/modprobe.d/floppy-pnp.conf alias pnp:dPNP0700 floppy alias acpi:PNP0700: floppy The final glitch I had to fix is that all Linux kernels I've tried have problems with DMA when writing to the built-in floppy controller on my motherboard (ASUS M4A78T-E). The symptom is that the driver writes the first 2 bytes and than hangs forever with the floppy motor running. Workaround for that is to add "floppy=nodma" as a parameter to the floppy module. That's almost certainly non-optimal (it applies to reading, too), but I don't use floppy disks often enough to care. I added a file in /etc/modprobe.d : $ cat /etc/modprobe.d/floppy-nodma.conf options floppy floppy=nodma -- Bob Nichols "NOSPAM" is really part of my email address.
