Hi all,
Let me begin by admitting that I am on a slightly different quest - I'm not looking to use OSX, but I do need to hack the BIOS of my D620 and I can see that this is one of the few sites on the net with the users and brains required to do the job.
My intended hack I believe is fairly minor. All I believe I need to do is to edit the DMI strings reported by BIOS to the OS. ( I need to do this because I am trying to install some industrial s/w that has recently included this limitation).
I also would like to change the BIOS splash screen, but tbh that is the icing on the cake, and if I have no cake I'm not bothered with the icing.
I have spent two full days trying to figure this out but only drawn blanks.
I have managed to use winphlash to retrieve the bios from machine, then tried to edit the strings but then got crc error as I have no idea how to calculate this. Also even tried to restore the backup file winphlash makes but I can't even get that to work - it looks like it nearly will if I use winphlash 1.6.5.6 but then it moans the bios is not flashable!
I am not looking for a solution to be handed to me on a plate, I wish to learn how to do this myself, but I am totally lost and have no idea where to begin!
