P166MMX is longer enough to handle this speed.

> Hi all,
>
> I've installed RTLinux v1.1 on a Toshiba Libretto CT100 notebook
> (Pentium 166 MMX) because we want to capture data from the serial
> interface at 500K Baud. Unfortunately, my module (based on rt_com) still
> loses bytes from the serial interface (i.e., I get the OVERRUN error
> from the UART). Running the "measure" example on the notebook shows that
> the maximal delay time for the scheduler can be as worse as 300
> microseconds. My own PC at home shows always a maximal delay of 20
> microseconds.
>
> Now my question: Could it be the case that the hardware is responsible
> for this behavior (i.e., because the notebook does not have a 2nd level
> cache)? Is there perhaps a cure?
