Hi Group...
At last i could connect to Internet using Pear PC on MAC OS X 10.2..
Various steps i followed were like this..
1) First i installed PearPC for MAC OS X 10.2
2) Downloaded Open VPN Beta 2.0 and Installed TAP Win32 driver on my windows XP SP1
3) Then started PPC...but no success!!!! i did not get any alert saying "New Network card found"...Where as i got a message in the command prompt syaing "Netwrok card initialized!"..
4) After fiddling around for 2 days..as per some of the group members suggestion..i installed 3com driver for linux downloaded from Pearpc.sourceforge.net on my PearPC emulator...using the steps given at the site..
5) Then i downloaded the pear PC 0.2 pre .zip from nightly builds site
6) Then changed the config file
pci_3c90x_installed = 1
pci_3c90x_mac = "de:ad:ca:fe:12:34" (i removed the windows one "pci_rtl8139_installed" and "pci_rtl8139_mac" from config file)..
7) And then started Pear PC...Clicked on System Pref-->Network option..

Bingo!!!!!!!!!!!!!!!!!!!!!!!!...To my surprise it gave me an alert saying "New Network Card Found"...then i had entered 192.168.0.18 in the IP address (random IP) after selecting "Using DHCP,set manually" option...and clicked on 'Apply Now' button....
9) Restarted Pear PC...Opened IE and went to apple.com to see the site in action...
Well i really don't know why this happened...my big doubt is..
Am i browsing internet using 3com driver or RealTek driver? Why did the "Local Area Connection" icon in my system tray is getting enabled even i did not mention "pci_rtl8139_installed" in my config file?..Well,Source forge guys may have to answer this...
And one more bug i identified was "Full Screen" option is not fully functional with 1024 resolution...It's functional with 800*600 ....
Thanks & Regards
Kiran...
