I installed CentOS4.4 on Dell optiplex sx280 but it doesn't recognize NIC. I read about problems for broadcom then I tried to install driver following the guidelines from broadcom. The guidelines says "build the binary driver for your kernel" and show the command "rpm -bb SPECS/tg3.spec or rpmbuild -bb SPECS/tg3.spec". But those commands are not able to run because of these errors (-bc: unknown option and rpmbuild: command not found).
How can I install the driver or if you have any other solutions please let me know.
