BIOS Updates forum

I recently updated my bios in XP , but then it went blank in its rebooting. Then i checked the solutions on the internet and find that there is one--The "Fn + Esc" one. i absolutely follow the steps like unpluging the battery ,unpluging the ac/dc cable and pluging the ac/dc cable after holding keys ...

i know why i can`t boot from the usb floppy~ when i enter the Caps Lock,there is no response which there should be something happen from the keyboard light, i guess when the bios failed, the keyboard hadn`t been
checked by motherboard, So the "Fn+Esc" method won`t help~

i follow the crisis methods,but it still can not boot from the usb-floppy.i don`t
know why ~
