Disklavier

Hi Folks, I've recently joined this group and have read some of the 
past correspondence between members and am impressed with the 
knowledge people have.
I have an Upright MX95 (serial # 4959049) which has a separate not 
built in Yamaha DKC5R Control Unit. The unit uses 720K 2DDformatted 
disks in ESEQ and has a MIDI function. Thanks to you guys I've been 
able to download a few MIDI tunes and play them through my PC 
running Windows XP Professional. I've also downloaded the 
dkvutilities program containing ESEQ Explorer, MID2ESEQ and 
ESEQ2MID,Veloset & dkvcopyI and need help with this.

I'm trying to Copy downloaded FIL files & MIDI files on to  floppys 
I can play through the Control Unit but am not getting anywhere 
despite following the readme instructions that came with the 
dkvutilities program. I'm not getting to first base.  I can't seem 
to format 720K discs on my PC. The Format option in Windows is set 
to 1.4 and does not allow any other format option to be made; Can't 
format through Windows DOS. I've tried changing the BIOS (during 
boot up) to the 720K format option but the PC looks for a 5.25 
drive. I've tried the different options in the floppy bios setup to 
no avail. If I format a disc in the Control unit the PC cant read 
it – says unformatted disc. At the risk of boring people, I would 
appreciate someone guiding me through the steps I should take on the 
PC to achieve the format process that will allow me to convert MIDI 
and TIF files to the ESEQ the Disklavier will read.
