I have a Acer Aspire 5315 with a CPU T8100
The BIOS contains the folloing problems.
-Max CPU is 2.00GHz not 2.10GHz
-I can't use different steps, the CPU is fixed at 2.00GHz
The official bios is no longer updated by ACER.
I have used a modified BIOS (icl50_1.45_black_edition_40.fd) that fix some problems (like VT support)
I have also updated the CPU microcodes on the BIOS, but not fix my problem with the DSDT
There is any way to improve the BIOS to get better support of T8100?

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 2.00 GHz - 2.00 GHz
available frequency steps: 2.00 GHz, 2.00 GHz
available cpufreq governors: conservative, powersave, userspace, ondemand, performance
current policy: frequency should be within 2.00 GHz and 2.00 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 2.00 GHz (asserted by call to hardware).
