You are useing AF under WinXP, so yes you are useing WinUAE...
Bdsocket is a small patch that allows (Win)UAE to use the TCP/IP-stack of the host-OS.
Don't try to use Genesis/Miami/AmiTCP on UAE !!!
You just need to check the "bdsocket"-flag in the UAE-setup dialog (where you can also select which kind of CPU and how much RAM the emulated Amiga should have).
As for the Peg-G4 ....
