 Hi!
 
 Forget to note that FDD works fine in FreeBSD 4.11
 that is installed here too. More, there is very strange effect:
 
 1. I boot FreeBSD 4.11 and make sure FDD works (mount FAT floppy, ls etc.)
 2. Warm reboot to FreeBSD 6.2-PRE and see that FDD became to work there too,
 it detects 1.44 floppy in drive at boot time, it reads all its contents
 to image with dd, it successfully formats floppy with fdformat
 and writes image back to the floppy with dd then mounts floppy Ok.
 2. Warm reboot 6.2-PRE again and FDD does not work again.
 
 This is 100% reproduceable.
 
 I did not try this machine's floppy with more early 6.x version.
