If I am running router or server on Compaq Deskpro EN (PIII 733 mHz, Motherboard Compaq 187498-001, Bios: Compaq Basic 09/13/02 686P2 v 3.14) how to boot up with unplugged keyboard? There is not option in Bios settings: "System boot stops for any errors except keyboard error". In POST screen it always shows: "304-Keyboard Error". Thanks
