===Intel Celeron M ===
The Celeron M is a budget processor based on the Pentium M. Compared to the Pentium M it has only half the L2-Cache and lacks the [[SpeedStep]] feature (excl. Banias family).

===Features===
*800-1600 MHz tact
*400 MHz FSB (Supports 533 MHz with CPU-Pin Hack and DDR2,see [http://www.overclockers.com/tips1204/ this] This puts the Clock speed in the 1066-2130 MHz range. Tested with a 370 Dothan)
*170 Million Transistors
*0.13µm or 0.09µm fabrication process
*512 KB or 1 MB L2-Cache
*QuickStart, Deeper Sleep
*[[SIMD|MMX]], [[SIMD|SSE]], [[SIMD|SSE2]] instruction sets

==Thermal Specifications==
The max. Core Temperature is 100°C.

==GCC 3.3 Optimization Flags==

CHOST="i686-pc-linux-gnu"
CFLAGS="-march=pentium3 -msse2 -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

==GCC 3.4 and Later ==

CHOST="i686-pc-linux-gnu"
CFLAGS="-O2 -march=pentium-m -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

Someone can expirence problems with GCC 3.4.5
The solution can be

CFLAGS="-mcpu=i686 -O3 -pipe"

==Speed Step==

For using the speed step with the celeron M you must add the module p4-clockmod.

==Kernel Options==

When compiling the kernel choose the pentium-M processot type
