appreciate your help.
dmesg.boot shows the processor as being:
CPU: VIA C3 Samuel 2 (601.37-MHz 686-class CPU)
Origin = "Centaurhauls" Id = 0x673 Stepping = 3
Features=0x803035<FPU,DE,TSC,MSR,MTRR,PGE,MMX>
[ ... ]
These VIA C3 processors are basically a low-power Pentium+MMX processor, and
I've used:
CPUTYPE=pentium
CFLAGS=-O2 -pipe
...OK under later 5.x and 6.x releases. Using CPUTYPE=i686/pentium2 resulted
in the bootloader and the kernel containing instructions which the CPU
couldn't handle (ie, the system halted and panic'ed) when I tried.
I believe you could use CPUTYPE=pentiumpro or pentium-mmx OK, but there didn't
seem to be any performance difference, and I'm leery of chasing the compiler
optimizer too far when it doesn't change the system performance by a noticable
amount.
