Ok some further info. I can put a single PATA drive converted to SATA onto an MCP55 SATA port, with 6.2 on it. It will bootup detect drives and shut down ok. More importantly the BIOS will then properly detect all drives at restart i.e. no problems at all. With 7.0 I have found that with just a proper SATA drive connected or even no SATA drives at all connected, after 7.0 has run the BIOS cannot then detect any drives at restart. It just hangs. Something 7.0 is doing is screwing up this controller. So not only is 7.0 failing to probe PATA-SATA converted drives, it is also messing up the controller full stop. There seems to be something screwy in the 7.0 ata code?
