I am trying to install vmware server on CentOS:
In vmware installation guide it says before intalling:

Before you begin, read the following notes and make adjustments to your host system:
The real‐time clock function must be compiled in your Linux kernel.
The parallel port PC‐style hardware option (CONFIG_PARPORT_PC) must be built and loaded as a kernel module (that is, it must be set to m when the kernel is compiled).

How Can i do that? what is command to do that?

Thanks.
