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

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
