Please can you help me with a few of missing bits. I have ordered an ASUS M2N SLI Deluxe which in addition to the NVIDIA SATA controller, has a JMicron 363 SATA controller which handles one internal SATA connector and an external eSATA connector. My understanding is that the JMicron will work using kernel AHCI support and the board BIOS has an AHCI setting. My hope is to be able to connect an Addonics AD5APM-E 5 disk port multiplier module to this. From the photo and some other information at their website, this appears to use either a Silicon Image 3124 or 3132 chip. Do you think this will work, if I use the current patch 20060710 on your Wiki? If so, and it supports hotplugging, which I believe it may do, what exactly does this mean? Can I power up an external enclosure containing the Addonics and 3 drives, configured as a RAID 5 and plug it straight into the running system? If so, can this be set up to mount automatically? Can I unmount the connected and mounted array and just unplug the array with no further concern? I hope I have not wasted your time by asking this. If the information is elsewhere, please let me know. Kind regards, Richard Scobie
