wireless Keybroad and mouse won't work

I installing windows xp then when it get installing devices my mouse and keybroad don't work i look at the bios but don't seem to have usb legacy

but it works in dos and strat up just not while installing windows xp

i plugged in ps/2 mouse and it works but i dont have ps/2 keybroad

is there way to get the wireless keybroad and mouse working.

 

don't know if this helps but on the bottom of the mouse there is a switch to turn on the mouse and same on the keyboard you should have a green light on

 

maybe its to do with the bios but i dont what i need to change please help

 

not really anything to do with the bios if you are plugging in a wireless mouse & keyboard
the receiver that's plugged into the usb port is it turned on where is says connect and do you have the light on in the bottom of the mouse

 

yes it is on
