When I install PNP modem , first be sure of its PNP mode.
and then setup BIOS ,
some guys like to disable COM2 (I don't think it is a good idea)
I often make PNP OS installed , to assign
IRQ3/IRQ4 to PNP or any other things.
Sometimes I succeeded,Sometimes I failed depends
on the motherboard.
I can not make a general conculsion about how
to setup BIOS to install PNP modem , and it is
suitable to most kind of motherboard.
Can anyone help me.
