Controlling PC motherboard?
Reza Khoshkish
Is any body know how can I controll a PC mainboard by simulating the
keyboard and Video card signals for fooling the BIOS? I want my own program
on a floppy take control of PC instead of operating system. Please inform me
if you know any solution for doing that.

if you are not given that option, get another MB

If your BIOS doesn't give you the option of continuing on errors, then
do the following:
(1) Get hold of an old keyboard. It must have working electronics
(usually just the one IC), but need not have functioning keys, or
LEDs. Use a hacksaw to cut out the electronics around the IC. Leave
the cable and connector intact, but cut through the traces going to
the key matrix. Throw this PCB stub into a box such as can be obtained
from electronic hobby stores and there you have it. Alternatively, if
you can find a keyboard with a membrane keypad (eg non-click types
such as Optima), then the job is even easier. The electronics in these
keyboards is located on a small detachable PCB (~14x6 cm).
(2) You can avoid VGA POST errors in the absence of a monitor by
adding three 75 ohm resistors between each of the RGB outputs and
their respective ground returns, ie between pins 1 & 6, 2 & 7, and 3 &
8.
