My purpose is to get my Asrock K7VT6 bios to recognise my new sata2 HDD. I have read several pages where are told this procedure to move some parts of bios from an another bios. MMTOOL does not work with my bios. I haven't found any other software to this job. Would someone please help me to find a proper program or perhaps to edit my bios? I have never done anything with any bios My mobo is Asrock K7VT6 and newest bios (ami) is k7vt6_160, with a controller via 8237 which could not recognise sata300. Unfortunately I could not post any links because this is my first message here. To get me more clear what I ment I put here following quote from discuss from Icequake.net: "I read some stuff on the Internet and I think that I have to use the MMTOOL v3.22 to replace the PCI Option ROM (DeviceID 3149) of the official 1.80 BIOS with a newer ROM, extracted from another BIOS. Personally, I used the VIA VT8237 option ROM from the GigaByte GA-VM800PMC, version 4.97 (237R497.rom)." I would much appreciate from any help to get this procedure going forward. I have spend hours already reading several pages about bios editing, nothing progress still ...
