I had them too. Booting the floppies worked okay, but later, after 
booting from the hard disk the first time the floppies (fd0)
are not recognized by the autoconfigure code. Sometimes I had success
when actually removing the floppy from the drive or powering off/on the
system. There still are some quirks in the fd driver.
