boot0sio is wholly dependent upon BIOS support for addressing the 
on-board COM1 port. It is not intended (read: very unlikely) to work 
with USB dongles.

If your BIOS does not support the call that it uses, then the symptoms 
will be similar to what you've seen. Unfortunately there is just not 
enough space in the MBR to implement any workarounds for this.
