The BIOS settings are locked. I extracted the .hdr and .rom files from dell's 3555A04.exe and copied to usb, then tried to power holding end key, but no luck. I can't find what to name the .hdr file. Also, the machine will not boot from DVD or USB probably due to settings lock. Please help! Thank You! service tag is 79BFMP1 , Express service code 15800876965, HDD S/N A6101947 (also pw locked)
my mistake on the model name--it's Vostro 3550. So now I'm trying with dell files 3550-A09.exe and 3550A11.exe converted to 3550-a09.hdr and copied to USB but can't get it to flash.
I was able to flash the BIOS by copying the dell .exe files to a HDD with Win 7 and running from Win 7, but the BIOS Setup Lock remains Locked with Admin Password Set and System Password Set. Can anyone tell me how to clear these?
