backtrack

This is my first linux,,,and I choose backtrack 3 final release, I think to use dual OS,,I need sometimes to insert my backtrack to the hard drive,, and when I got it, I have another problem… where is my wifi,, my wifi didn’t detect on backtrack 3. My Wifi is Rtl8187b and the backtrack use 2.6.21.5. In that kernel Rtl 8187b wasn’t include, so I upgrade my kernel to be 2.6.28
Follow this step to upgrade your kernel
1. download kernel from ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.tar.bz2
2. tar xvf linux-2.6.28.tar.bz2 -C /usr/src/
3. cd /usr/src/linux-2.6.28
4. make menuconfig———–after you done, it will show configuration and you must choose your wifi,don’t forget to include file system
5. make && make modules-install
6. cp -v arch/i386/bzImage /boot/linux-2.6.28
7. cp -v System.map /boot/System.map-2.6.28
after that dont forget to apdate your lilo or grub
and type “lilo”
last “reboot”
good luck friend
