I tried something different this time; I compiled my kernel without SMP.
Why was my kernel built with SMP, you ask? Well, it wasn't my idea. Linux 2.1 seems to default to "SMP = 1", so I had to go in and turn it off. Took me a while to figure that out.
So anyway, now I get this:
/proc/cpuinfo: processor : 0 cpu family : 4 model : 6x86MX 2.5x Core/Bus Clock vendor_id : CyrixInstead stepping : 1.3 fdiv_bug : no hlt_bug : no sep_bug : no f00f_bug : no fpu : yes fpu_exception : yes cpuid level : -1 wp : yes flags : bogomips : 149.91
It looks a little bit better, but the "cpu family" is still 4, rather than 6, and the "cpuid level" is still -1, instead of 1. Also there are no "flags" listed for the cpu, like there should be.
Also, my boot message shows this:
CPU: Cyrix 6x86MX 2.5x Core/Bus Clock stepping 1.3
I don't understand how the system can get a "CyrixInstead" vendor_id out of the chip if the "cpuid level" is -1. That doesn't make much sense.
