an Intel Core 2 Duo (codenamed Merom) processor with a 667 MT/s FSB for Napa Refresh platform, or.an Intel Core Solo, Core Duo (codenamed Yonah) processor, or.
The platform initially supported Intel Core Duo processors but the newer Core 2 Duo processors were launched and supported in this platform from Jonwards.Īn Intel Mobile 945 Express series chipset (codenamed Calistoga with Intel GMA 950), including ICH7M southbridge. The codename Napa designates the third-generation Centrino platform, introduced in January 2006 at the Winter Consumer Electronics Show. Unfortunately, the introduction of PCI Express and faster Pentium M processors causes laptops built around the Sonoma platform to have a shorter battery-life than their Carmel counterparts Sonoma laptops typically achieve between 3.5–4.6 hours of battery-life on a 53 W-h battery. The Mobile 915 Express chipset, like its desktop version, supports many new features such as DDR2, PCI Express, Intel High Definition Audio, and SATA.
Īn Intel PRO/Wireless 2200 BG or 2915 ABG mini-PCI Wi-Fi adapter (both codenamed Calexico2). an Intel Pentium M (codenamed Dothan) processor with a 533 MT/s FSB.
Intel used Sonoma as the codename for the second-generation Centrino platform, introduced in January 2005.Īn Intel Mobile 915 Express series chipset (codenamed Alviso with Intel GMA 900), including ICH6M southbridge. Carmel also allowed laptop manufacturers to create thinner and lighter laptops because its components did not dissipate much heat, and thus did not require large cooling systems. Carmel could attain or exceed the performance of older Pentium 4-M platforms, while allowing for laptops to operate for 4 to 5 hours on a 48 W-h battery. Later, Intel allowed the 855GME and 855PM chips, which did support external graphics, in Centrino laptops.ĭespite criticisms, the Carmel platform won quick acceptance among OEMs and consumers. Initially, Intel permitted only the 855GM chipset, which did not support external graphics. At the same time, they permitted the new Dothan Pentium M to substitute for the Banias Pentium M. In early 2004, after the finalization of the 802.11g standard, Intel permitted an Intel PRO/Wireless 2200 BG to substitute for the 2100. Intel responded that the IEEE had not finalized the 802.11g standard at the time of Carmel's announcement.
Industry-watchers initially criticized the Carmel platform for its lack of support for IEEE 802.11g, because many independent Wi-Fi chip-makers like Broadcom and Atheros had already started shipping 802.11g products.
Once you have the firmware loader in place (or if you aren't sure and you just want to try things to see if it works), you need to install the firmware file into the appropriate location.Notebook implementations Carmel platform (2003) The steps for installing and configuring this are very distribution specific and the tools differ, but distributions have this enabled. In addition to having the firmware_class support in your kernel, you must also have a working userspace infrastructure configured. You can determine if your kernel currently has firmware loader support by looking for the When you configure the kernel, you can find this option in the following location:
In order to function correctly the driver requires this to be enabled in your kernel. More information can be found under in the Documentation/firmware_class/README file in the kernel source. The driver loads the firmware using the kernel's firmware_class infrastructure. If that doesn't work, or you need newer firmware, read on.? Note that many distributions ship the firmware, you could install the “linux-firmware” package or similar. The firmware necessary to support the devices is distributed separately under the firmware license.
