    initial v1  
    11Added two (yet uncommitted) patches:
    221) http://trac.netlabs.org/vbox/attachment/ticket/45/cdflop-avail-upd.diff, update to floppy-detection code, distinguishes between floppies and other media types. Known drawbacks: considers erased CDRW's to be floppies.
    3 2) http://trac.netlabs.org/vbox/attachment/ticket/45/host-cdflop.diff, host CD/floppy attach code. Opens/writes/reads/ejects/locks/unlocks door on the CD/floppy on the host computer. Known bugs: a) floppy performance is poor, because it VBox asks for 1 sector at a time. Need to try reading by 1 track at a time b) it traps sometimes when floppy is inserted, on some VM's c) traps rarely in pmmerge, probably, because of stack corrupting d) erases CDRW successfully, but I still have got a trap when trying to write ISO to CDRW in Nero in guest winxp.

Need to find the way to distinguish between CD and DVD.
