Compiling drivers in SMP mode

I'm running SuSE Enterprise Server 7 on a dual processor ia32 and trying to compile driver source. I'm relatively new to Linux. Initially I received two warnings: kernel source version (2.4.7) does not match running kernel (2.4.7-64GB-SMP) and kernel source configuration (UP) does not match running kernel (SMP) I was able to eliminate the first warning by running "make include/linux/vershion.h CONFIG_SMP=1 CONFIG_HIGHMEM64G=1" which fixed the UTS_RELEASE define in version.h. But I don't know how to configure the source for SMP at compile time. Any pointers appreciated. Chris H
