I've added an XTIDE rev 4 card to an Amiga 2K, but have no idea what to set all 16 dip switches to for this config, and Google has failed me. Is there any guidance you can give? What I've found so far is that the ROM address is fine at the default of D000, but I've no idea what IRQ to use, and the XTIDE came with no instructions. Searching turns up mostly results for rev two of the board, and almost nothing for rev 4.
