Driver Installation 11 At the loader prompt, load twa.ko from the floppy using "load disk0:twa.ko" (assuming disk0 is the floppy drive). 12 Remove the floppy and then boot by typing "boot". 13 Once the system boots up, replace the twa driver sources at /sys/dev/twa and /sys/modules/twa with the new sources and build the kernel with the new driver sources. See "Updating the Kernel with the New Driver Source" on page 199 for more details. 14 Reboot your system. Installing the 3ware Kernel Driver on a FreeBSD System that Boots from a Different Device Use the steps in this section if FreeBSD boots from a different device and you will be using the unit on your 3ware RAID controller for secondary storage. When you use the unit managed by the 3ware RAID controller for secondary storage, you do not need to use a driver diskette for driver installation. Tip: Install FreeBSD on the drive attached to the mother board before installing the 3ware RAID controller. This avoids the possibility of installing to the wrong drive or unit. 1 Get the latest driver source files for your version of FreeBSD. See "Obtaining 3ware Linux Drivers" on page 43. 2 Make sure the 3ware RAID controller is not yet installed in the system. 3 Install FreeBSD on a disk attached to the motherboard. Be sure to install the full FreeBSD source. 4 Once FreeBSD is installed, power down the system and install the 3ware RAID controller. For assistance, see the installation guide that came with the controller. 5 Create the RAID unit or units on drives attached to the 3ware RAID controller using 3BM. For details on how to create and order units, see "Creating a Unit through 3BM" on page 91of the 3ware SAS/SATA RAID Software User Guide, Version 9.5. 6 Boot to FreeBSD. 7 Follow the instructions in "Updating the Kernel with the New Driver Source" on page 199 to update the kernel. 56 3ware SAS/SATA RAID Software User Guide, Version 9.5.1
