“The ecn26j60 will only work if i disconnect the 2 pfc8574, But i don’t have any relays working” — that’s just because the firmware detects the existence of these chips to tell which version of hardware it is, and as you know, it only enabled ENC28J60 for OS 3.2. There is a good reason for that, because earlier hardware versions use some of the SPI pins for other purposes, so if you enable ENC28J60 for the earlier hardware versions, then those SPI pins will have unexpected behavior that should be avoided. So my suggestion really is to follow OS 3.2 design.
