Какой BIOS может игнорировать встроенную графическую карту и просто использовать дискретную графическую карту?

Я использую ноутбук GT630M, ubuntu 12.04 64 бит.

Вот моя информация о BIOS:

  sam@sam:~$ sudo dmidecode -t bios
  # dmidecode 2.11
  # SMBIOS entry point at 0x000f04c0
  SMBIOS 2.7 present.

  Handle 0x0000, DMI type 0, 24 bytes
