Wish I didn't have to come back so soon. For some odd reason the networking drivers aren't being detected (I made sure they were lower-case, and to make double sure I moved them to an exfat partition I had so they wouldn't be case-sensitive, and I did point the config file to that partition), I also noticed I couldn't click the "configure host" button. Whenever I click on the networking tab, or clicked configure host this, I'm getting this error:
You need to run ./configure with --enable-networking swith for the build to have networking support. Using slirp is included in the sources. I think that additional sources are needed for pcap support (i haven't tested that much).
Also, I don't know what you mean with drivers. You need to install the drivers inside of the guest OS, not on the host OS.
Also, be aware that the NE2000 configuration might need some adjustment for it to work initially. Verify that the port and IRQ are the same on PCem's configuration and on the guest OS.
