I have GA-MA790GP-DS4H motherboard, reading from the manual: it has OnChip SATA Type (SATA2_0 ~ SATA2_3 connectors) Mode: Native IDE RAID AHCI - Advanced Host Controller to enable advanced Serial ATA features such as Native Command Queuing and hot plug. Is it the one AHCI? I've never used it. I'm more interested in configuring it as an auxiliary drive "sdb" to serve as a bootable backup. The box will be installed in a remote location and I'll have an ssh access to it. The box is running in a medical clinic and I'm mostly concern that after the emerge if something happens, I want the user to be able to boot "grub" from second drive, and it will be "sdb" (hd1); but during normal operation, when running from "sda" I want to backup some application files to it so "sdb" stays current. -- Joseph
