Hi,
This seems a silly question but - I have an intel celeron 800mhz CPU and thus
it is of the Coppermine breed. But under cpu selection when configuring the
kernel, should I select PIII or PII/Celeron? Just wondering, since Coppermine
is basically a newish PIII with 128K less cache...
TIA

Try both, and see if your machine throws up.

800Mhz Celeron is actually a CeleronII, and it does SSE just like PIII (the
only difference being cache). Therefore PIII option should work.
Perhaps this should be fixed in the config menu (or is it already? Which
kernel are you compiling?)

You should select PIII. Configure.help already says that, but here is a
patch against linux-2.4.4 that reflects that change in
arch/i386/config.in as well. Please apply.

PIII, the differnce in the options is stuff like SSE that your PIII/Celeron
has.

compiling kernel 2.4.4 on mandrake 8.
Just checked - no mention of Celeron II in there-
Pentium Pro/Pentium II/Celeron
is the only line mentioning the celeron; maybe the PIII line could be changed
to something like "Pentium III/Celeron II"?
I would supply a patch, but I don't know how to write such a thing :)

It seems Erik Mouw already submitted a patch, altough I agree that "Celeron
II" might be a better name for the thing than "Celeron (Coppermine)".

So what about this one? This time I had to change Configure.help and
setup.c as well to reflect the changes in config.in :)

Hmm. I just checked Intel's web site (should've done so earlier), and it
appears that Intel still dubs the new revision as "Celeron", although I'm
sure it was introduced as CeleronII in some sources (try
http://www.google.com/search?q=CeleronII). So I'll just have admit that your
first patch was technically correct, and I was wrong. Sorry for the
inconvenience.
I still think "Celeron II" is clearer, but heaven knows what Intel will sell
by that name three years from now (just think of i860).
