===Intel Mobile Pentium M (Dothan)===
The Dothan Pentium M is the second generation Pentium M processor. The fabrication process was reduced to 0.09µm and the L2-Cache was doubled to 2 MB. A second generation of Dothan Pentium M processors features a 533 MHz FSB and accompanies the Sonoma Centrino platform.

===Features===
*1.0-2.26 GHz tact
*400/533 MHz FSB
*170 Million Transistors
*0.09µm fabrication process
*2 MB L2-Cache
*[[SpeedStep|(Enhanced) EIST]], XD-Bit
*[[SIMD|MMX]], [[SIMD|SSE]], [[SIMD|SSE2]] instruction sets

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

==GCC Optimization Flags==
You should use the following for GCC version 3.4.4 and later if you have a Pentium M:
-Os -march=pentium-m -pipe

For GCC version 3.3.5 and earlier use the following:
-Os -march=pentium3 -msse2 -pipe

Also, if you don't plan to use debugging information, then you can safely add the following to either of the above for a possible performance improvement:
-fomit-frame-pointer
