Hello. So i was browsing for 7 days, i'm currently using my home made computer due to the problem with my Dell. well at first everything was working like a charm, i installed the DVD-Writer and put it in Slave mode. that day, when i wanted to install Vista on it, i tried to make the DVD-Writer as a primary drive, when i entered the BIOS, everything was alright but when i tried to change anything it tell me that the SETUP is locked, there is no password at all, its just this Factory password, so i tried to remove the Battery like has been suggested everywhere, but unfortunately XP isn't working at all, neither from the safe mode, all i get is that windows cannot start probably. tried to enter the BIOS, the date is back to 2005, and the factory password was still on, and the setup is locked. now, i think my problem is in the BIOS, i need to put my dvd-writer as primary, but i need the Master Password. I tried to contact Dell but they needed some details that i don't have, its just they are asking too much and i just have few info. and above all, i don't have a fax machine. so any help would be appreciated.
