AVG / DOS

I have created a set of startup floppy disks (two disks) for AVG
using AVD > > http://www.avdisk.org/pages/download.html .
( I used AVD for F-Prot that is working fine ).
The diskettes were succesfully created... When I boot
and type "AVG" to the prompt I get the AVG GUI .
But when I want to test the disk, I get "OK" and only 1 object
is tested ! No scan is performed !
Any help ? thanks a lot.
