+ floppy=broken_dcl
+ Don't use the disk change line, but assume that the disk was
+ changed whenever the device node is reopened. Needed on some
+ boxes where the disk change line is broken or unsupported.
+ This should be regarded as a stopgap measure, indeed it makes
+ floppy operation less efficient due to unneeded cache
+ flushings, and slightly more unreliable. Please verify your

+ floppy=debug
+ Print debugging messages

+ floppy=messages
+ Print informational messages for some operations (disk change

+ floppy=silent_dcl_clear
+ Uses a less noisy way to clear the disk change line (which
+ doesn't involve seeks). Implied by daring.
