Well, all I wanted to do is to get rid of these IDE cables inside my desktop case, just to gain more space inside. So one friend of mine lent me his SATA to IDE adapter he bought. This adapter supposed to work under Amiga, as a guy stated in a thread on Amiga.org's site.
This adapter you can find it here.
I received it today and I tested it. I have good news and bad news.
Good news first:
My Amiga recognised my SATA HD I've connected to; using HDToolBox. I loaded up Workbench and I've already formatted it. So far so good.
Bad news second:
My Amiga refuses to recognise my SATA DVD-ROM as a scsi.device, unit=1 (that's supposed to be the correct one configuration, if you use normal IDE HD and DVD-ROM combination).
I tried to play with the adapter's jumper, it has a Master/Slave jumper, but with no luck.
Thus, it's impossible install AmigaOS 3.9 again in my SATA HD.
Any ideas how I can get these 2 SATA devices to work together?
