New firmware upgrade. This new release fixes one bug that affected the video buffer manager and lead to wrong appearance/disappearence of chars when positioning the cursor in different locations with LOCATE. Other changes involve the serial and audio sections: the SIO special condition interrupt won't reset the system anymore; the audio init code has been revised and optimized.
