I was using a VERY old PC (my grandparents computer for those who read my other thread) and I was thinking that if it had a decent modem, the internet connection wouldn't be so bad. However, when my uncle and I try to put in a new modem, the computer doesn't recognize it. Now, I think it has to be because the motherboard is so old and the modem is new, but what can I do to get it to work without putting any money into it? Will a BIOS flash help?
