    According to Intel specs, i5-2410M does not have AES-NI
    Intel® Core? i5-2410M Processor (3M Cache, 2.30 GHz)

    But at very end of the page there are statement: "Some products can support AES New Instructions with a Processor Configuration update, in particular, i7-2630QM/i7-2635QM, i7-2670QM/i7-2675QM, i5-2430M/i5-2435M, i5-2410M/i5-2415M. Please contact OEM for the BIOS that includes the latest Processor configuration update."

    So, for unlock AES-NI you need updated BIOS with new CPU microcode revision. For Compal PBL20/21, BIOS since v.2.10 include microcode revision 1A, which unlock AES-NI.

    I've flashed latest BIOS v.2.50 (was 1.71) and now AES-NI is ON. :) Benchmarks in Truecrypt give speed 1.3GB/s for AES algorithm (without hardware acceleration only 240MB/s).
