Thank you. 
The transfer rate was around 64 K/s. 

Anyone can instrust me how to build a boot image? I tried one to build a custom one 
with the following steps.. 

dd if=/dev/zero of=customboot.fs count=5760
vnconfig -t floppy288 -v -c /dev/vnd0d customboot.fs
disklabel -rw /dev/vnd0d floppy288
newfs -B le -m 0 -o space -i 204800 -c 80 /dev/rvnd0a floppy288
/usr/mdec/installboot -v -f /usr/mdec/biosboot.sym /dev/rvnd0a
mount /dev/vnd0a /mnt
gzip -c -9 /usr/src/sys/arch/i386/compile/CUSTOMBOOT/netbsd > /mnt/netbsd
chmod a+x /mnt/netbsd
umount /mnt
vnconfig -u vnd0d
mkisofs -o customboot.iso -b customboot.fs -c boot.catalog -a -l -J -r -L /cdresources
