You don't have to remove the battery for a semi-soft BIOS reset. Turn off your DT366, press and HOLD the power button. Keep holding for about 3 seconds and you will see the center LED come on. Keep holding it in maybe 5-6 seconds total and the left most LED will flick an the power will go off. Then you can let go of the power button, push again for a normal power up. This trick will load the default BIOS settings but leave the time and date untouched.
I have a few tricks I have found with this thing. This is a good one for the fool that wonders if you can gain system RAM by changing the video memory from 16mb to 8mb then it would be cool to get more memory by setting the video memory to zero. Or maybe the bonehead that wonders what that "X2" is in the display type - I can use it twice the size.....
These other numb-skull moves can be easily corrected with this semi-soft BIOS reset.
Of course, not me...... -Dave
