And among so many IO devices , i would rather start first with the PCI Express SLOT hotplug,putting something like scsi a little later. 2 there are few mainboard that support pci express hotplug nowadays ,but i found one which maybe useful: that is the intel E7520AF2 server board using the E7520 chipset.now the Dell PowerEdge 2800 is said to support pci express hotplug ,but till now i doubt the bios of the 2800 do not support ACPI _OSC or OSHP method yet. i am contacting with dell now 3 according to linux and openbsd ,hotplug archtecture is rather clear , a thread waiting for the interrupt from the slot ,do the init and driver-attaching then leaves it to userspace 4 i am so small and fragile ,so any gentlemen would like help are warmly welcome!! --=20 we who r about to die,salute u!
