PS/2 Keyboard Numlock On/Off

Hi

My platform is NSC Geode GX1 and Windows CE .NET 4.1.

I want to add a feature, it's let user to choose the numlock status
after the machine power on.

It's very same as the NUMLOCK ON setting in PC's BIOS.

I read throught all of codes in ps2_8042 floder, then the following
codes into ps2keybd.c.

BOOL
Ps2Keybd::
Initialize(
Ps2Port *pp2p
)
{
...
v_pp2k -> m_pp2p -> KeyboardLights(0x2);
...
}

I think those codes will let keyboard light the numlock LED while it's
initializing.

But I got nothing.

Why?

Anyone can help me?

Setting the LED like that should work, but it is not the right way to do it
since the keyboard driver bases the LEDs on the current internal state.

What you should probably do is have something call keybd_event(VK_NUMLOCK,
... key down) at boot. This could even be the keyboard driver calling it.
This will set both the internal NumLock state and the LEDs to match.

Yes, Yes, Yes

I did this task for 3 days.

Then use 1 command to solve it.

Thanks
