Mam nadzieję że przestawiłeś ten jumper "Slot/Socket"
Jeżeli w Twoim egzemplarzu jest bios AMI (podobno bywały też Awardy), to pokombinuj Amibcp (ustaw defaulty pod konkretny system). Jak pisałem u mnie zadziałało. Najlepiej postaraj się o drugi EEPROM - będzie bezpieczniej. Ja musiałem kombinować dłuższy czas. No ale to tylko PCChips
Spróbuj też jakiegoś wcześniejszego biosu:
