        MegaRAID Enterprise 1600 Hardware Guide

Configuration on Disk (drive roaming) saves configuration information both in NVRAM on
MegaRAID and on the disk drives connected to MegaRAID. If MegaRAID is replaced, the new
MegaRAID controller can detect the actual RAID configuration, maintaining the integrity of the
data on each drive, even if the drives have changed channel and/or target ID.

MegaRAID can be installed in an IBM AT®-compatible or EISA computer with a motherboard
that has PCI expansion slots. The computer must support PCI version 2.1 or later. The computer
should have an Intel Pentium or more powerful CPU, a floppy drive, a color monitor and VGA
adapter card, a keyboard, and mouse.
