    Since this Dell Studio 1450 uses a regular Phoenix BIOS (i.e. WPH), you need to search in the executable for the string "NAPI". Then you need to play around with 256KB (0x40000) offsets to find the beginning and end of the BIOS ROM and cut it out of the executable.

    For the 1450_A06.EXE, I cut the range 0x2FEE00 to (0x4FEE00 -1). I found those based on the NAPI string and the start of the platform data signature "BCÖñ" at 0x4FEE00.

    Code:
    NAPI -1536K => 0x2FEE00 = 3141120  (start block)
    NAPI        => 0x47EE00 = 4713984
    NAPI +512K  => 0x4FEE00 = 5238272  (so use 5238271 as the end block)
    
    Here's some old posts from Yen regarding the NAPI string.

    Hi tqhoang,

    Can you mod this bios to disable whitelist check ? accidentally i broke my lcd and tried to replace it with compatible one from ebay. since its not from dell and it does not have exactly same part number bios is not accepting it and giving 8 beep. (Laptop studio 1450, Service tag 97GG4BS, Old lcd is from samsung and new is LG)

    Even though this thread has been inactive for five months, you still responded to my post. All i can say is THANK YOU VERY MUCH! This day, i will try to repair my 1450 by the ROM and WPH you provided.
