PCMCIA driver package

I found the package (I think) I need for the 3COM ...556... modem/net
card on my PC. But every time I try to download it from RedHat, I get ma
message (running from my NT system) 'do I want to install Real Player'
!

Why, how?? This is a bit of insanity! Will all **.rpm files give me this
from windoze based access?

Thanks for any info!
