steering the BE# ?

[tw38966@is1.bfu.vub.ac.be (Rafiki Kim Hofmans)]

Hi,

how can I steer the BE# ?

e.g for a target-only device :

Suppose I want to do a write a byte to targetaddress (Base address +
0001)  with IO mapped IO. 
How can I set the BE#, can it be done through software ?

Suppose I want to write a double word to targetaddress (Base address +
0011) with IO mapped IO, what happens with the BE# ?

And in case of a memory mapped IO write to the same address, what happens
with AD1 and AD0 ?

Thanks,

Kim
