So this isn't a bios mod persay, but rather an interesting situation. There seem to be many people on this board knowledgeable about BIOS programming, so I thought I'd ask for some help. I have a Vostro 3400 laptop that recently had a motherboard replacement. For whatever reason, the motherboard came incorrectly flashed with a Vostro 3500 bios. Now, the 3400 and 3500 are very similar, so it works, but I'd like to re-flash it to the correct model. I'm having difficulty getting Dell to exchange the motherboard again as the customer service people don't understand the issue and it's not malfunctioning persay, it's just...wrong. I downloaded 3400_A10.exe from Dell. When running from Windows or DOS it I get the message: "Can't find Rom image to match with Main board." Interestingly, I can flash the 3500_A10 just fine... I know with some older Dell BIOSes, you could force it to flash using the parameter -forcetype from DOS. That doesn't work with the 3400 BIOS exe. Does anybody know of an equivalent switch I can use? Or some other way to force this thing to flash to the correct model's BIOS? Thanks for any help, I really appreciate it!
