which kernel?


on two different sid-installations i got different kernels installed by usual upgrades.
2.6.29-2-686; which seems to be the actual one for sid
and
2.6.26-2-686
2.6.26-2-486

till now i allways used the 686-kernel.
whats the difference between 686 and 486 or how may i find out which one(486 or 686) to take?
thanks a lot for a help

If I were choosing between the 686 and the 486, I would use the 686 always. I googled "386 vs 686" and came up with this on the Debian User Forum:

To quote, in 2007 'Zen-Owl' said

As far as I understand, an i486 kernel is optimized for all Intel Pentium processors and AMD processors, i686 is optimized for Pentium 4's and AMD Athlon.

The 486 package targets an older hardware platform. The 686 platform came out with Pentium II intel compatible chipsets. The 486 would be compatible with more hardware but would not be optimized if you run linux on recent hardware. You might have to run the 486 kernel for some AMD processors too.

That's a 4. Pentium 2 is pretty old at this point, the processors in the second generation were between 100-450 mhz or so, its been years since I've seen one.

Peace,
