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
Physical Address Extension (PAE)
Most modern Linux distributions use PAE kernels which will fail to boot if this feature is not present in the CPU. The Dothan core is said to support PAE even though it doesn't report the feature to the operating system. As a workaround, kernel parameter forcepae
can be used to successfully use PAE-kernels on any Dothan core.
All second generation Dothan models with a 533 MHz FSB and some newer model first generation Dothan cores with a 400 MHz FSB do report PAE and NX in their CPU flags. All others must use the workaround.
Note: As a direct result, when the CPU flag PAE and NX (No eXecute, the XD-Bit) is not reported, 32-Bit-Windows starting with Windows 8 will also not run (Windows doesn't have a forcepae option), leaving 32-Bit Windows 7 the last supported Windows operating system on Pentium M CPUs before the second generation Dothan core.
