I believe that in the early days of Centrino Intel was forced to partner with other WIFI chip makers to meet their release date. Which may have set the standard lower than was expected from the very beginning. It may also be as simple as the chassis being pre-stickered Centrino and assembled with a Broadcom chip due to a back order on the Intel chips. Byron -- gentoo-user@gentoo.org mailing list

No pentium m processors have integrated wireless. the pentium m is a cpu. However centrino machines have built in wireless, its part of the centrino spec. centrino also uses pentium m. but just because your machine has a pentium-m cpu, doesn't make it centrino. lspci should tell you if you have a wireless chipset in your machine. If it has a centrino sticker, then it should have wireless. Hope that clears up the confusion. -- Nick Rout Ha I was told it would cost extra to get a computer without windows.

(Answer: Because MonopolSoft threatens vendors into doing this.) I suggest NOT buying from vendors that do this. If Linux ever reeally becomes *important* in the $$market, they'll pay for that behavior. Hopefully, that will feed back to MS hurt them even more. I think windows devalues the computers Travis R.

They (Intel)took the awesomeness of the Pentium3 family, added the cool SSE stuff from theP4, gave it a lot of on-die cache (the Dothan core has 2 MB L2 cache), increasedthe instruction pipline, and also made it consume a _lot_ less power. In fact,when the P4 came out originally I honestly thought that it would be the end ofIntel; then they started producing their Centrino[2] laptop chipset (Pentium Mwith Intel mobile chipset and integrated Intel PRO/Wireless). It consumes verylittle power but it can perform really well. In fact, My brother gave me a goodrule-of-thumb about this when he was explaining it to me a while back: Add 1 GHzor so and that's the equivalently rated P4. For example, a 1.5 GHz Pentium Mwill likely perform just as well, if not better, then a ~2.5 GHz Pentium 4.[1] http://en.wikipedia.org/wiki/Pentium_M[1] http://en.wikipedia.org/wiki/Centrino--()The ASCII Ribbon Campaign - against HTML Email,/\vCards, and proprietary formats.---Peter A.

However, the P4 can't really do a lot per cycle. Intel is moving towards incorporating a lot of Pentium M features in their desktop processors. Unfortunately the results for Linux are somewhat mixed...extra cache is good, but gcc treats it as a regular P4, and misses out on a bunch of features.
