Well like I said I have it working, OEM-pre-activated with windows 7 and put my modded BIOS through an extensive amount of hours of building, and testing on the presario v3000 hardware - so I'm confident that it won't brick anybody's laptop.
Thanks dviper785 your bios mod works great on mi Presario V3217la, it should work on the v3000-v3400 series because they have the same motherboard only some minor changes (Ram CPU HD) between each model. Regards from México.!!!
