Battery MOD on Dell Inspiron E1505

[masster]

hi
I would like to bypass the power charger check Dell Bios is doing so that I can use a standard 2-wire charger instead of special 3-wire type. The best option would be a new setting in Bios menu: Bypass? yes/no

I extracted MM061A17.rom using MM061A17.exe -writeromfile but when I tried opening it in Phoenix Bios Editor Pro 2.2, I got an error: No BCPs found!

So I would need a little guidance here, please.
