Re: Problem of 1.0-8762 installation in 2.4.21--need help!
You stated that "I setup and configure the 2.4.21 kernel-source". If you're running RHEL3, all you need to do is install the kernel-source RPM that Redhat provides. If you've done anything beyond that, that's likely the source of your problem.
If you need further assistance, please post the NVIDIA installer log.
