Both SiI and nForce's should support hot-swap, though if ata(4) actually handles them correctly is another matter. I have an nForce 4 Pro board (a Tyan K8WE, CK804 chipset) which in FreeBSD gracefully handles hot removal, but needs a reboot to correctly recognise hot-plugged devices. I thought I'd filed a PR about it, but I can't seem to find it... I also have an 8 port Marvell SATA controller (88SX6081) which needs an atacontrol reinit to pick up new devices, but otherwise seems to work fine. -- Thomas 'Freaky' Hurst http://hur.st/
