Okay...
So, I'll take it from the start now... since I do know how to solve the problem, but it isn't possible to do it the way I am supposed to.
1. To get my HD up and running I need to patch the scsi.device.
2. I'm running a Blizzard 1260, and to patch the scsi.device I need to have it in FastROM mode. (I'm trying to use Frap to do the patch, can't find any other program).
3. When the scsi.device is patched, I need to extract it from the ROM, using GetSCSI, and turn it into a "real" device that I can put into Devs.
4. After all this is done, I can softkick everything up to 3.1, since I don't currently have my 3.1 ROM in this very A1200.
But, Frap refuses to work. It simply says "Unable to write into the FastROM".
No matter if i turn on or of my only jumper on the 1260.
