maybe u should try tutorials on youtube.

i agree with maverick.

case Hash Sum missmatch use no-cache option on apt-get, for example:

apt-get update -o Acquire::http::No-Cache=True

check this http://www.backtrack-linux.org/forums/showthread.php?t=52532

what about others linux, like ubuntu or opensuse, is there a same problems like u wanted install backtrack ?

try another way, maybe using addtional driver.

just search available driver on amd.com

hello all, let me try a lot tutorials in this forums ;)

thanks man, this worked.
