I upgraded my cpu to a sempron with 64bit extension (Sempron 3400+ for
754, to be precise). After some googling and reading, I still can't
figure those out:

- Why do some instruction flags don't appear at /proc/cpuinfo? sse3 and
x86-64, specifically. Do they have different names? (output follows).
According to a tom's hw chart, there's no such thing as a sempron 3400
for 754 platform without sse3 and x86-64.

The machine now runs a 64bit sarge netinstaller (which it didn't
before), so I know the 64bit instructions are there. Is the complete
64bit reinstall worth the hassle?
just guessing...
what kernel are you using?



kernel is 2.6.8-2-k7 stock sarge.


i havent tried though i doubt that a normal 686 or k7 kernel supports
either of these extentions and therefore will not test for them...

what does it say when you start the amd64 installer and open a console?




I didn?t try that. Will try as soon as I get back home.
thanks for the tips, albert. I?ll try some livecd?s as well.
One clue: mplayer?s ./configure told me arch is 'k8', instead of 'k7'.
By the way, here?s the processor:
