Chapter 7: Installing the Driver and an Operating System 66

5Type the following commands to begin loading the driver:

mkdir /mnt2 /AACRAID mount /dev/sda1 /mnt2 cp -R /mnt2/* /AACRAID umount /mnt2

6Copy the driver file to the /lib/modules directory:

cp -f /AACRAID/aacraid.ko-PRE_MOD /lib/modules/2.6.<version>-generic/kernel/ drivers/scsi/aacraid/aacraid.ko

where <version> is 32-24 for Ubuntu 10.x and 38-8 for Ubuntu 11.x.

7Remove the USB drive.

8Install the loadable module:

insmod /lib/modules/2.6.<version>-generic/kernel/drivers/scsi/aacraid/ aacraid.ko

where <version> is 32-24 for Ubuntu 10.x and 38-8 for Ubuntu 11.x.

9Press CTRL+ALT+F1 to switch back to the installation screen, then follow the on-screen prompts to continue the installation.

10When prompted to reboot the system, press CTRL+ALT+F2 to switch to the console. Do not reboot!

11Type the following commands to complete the driver installation:

For Ubuntu 32-bit:

cp -f /AACRAID/aacraid.ko-POST_MOD /target/lib/modules/2.6.<version>-generic- pae/kernel/drivers/scsi/aacraid/aacraid.ko

chroot /target

/sbin/depmod -a 2.6.<version>-generic-pae update-initramfs -u -v

exit

where <version> is 32-24 for Ubuntu 10.x and 38-8 for Ubuntu 11.x.

For Ubuntu 64-bit:

cp -f /AACRAID/aacraid.ko-POST_MOD /target/lib/modules/2.6.<version>-server/ kernel/drivers/scsi/aacraid/aacraid.ko

chroot /target

/sbin/depmod -a 2.6.<version>-server update-initramfs -u -v

exit

where <version> is 32-24 for Ubuntu 10.x and 38-8 for Ubuntu 11.x.

12Press CTRL+ALT+F1 to switch back to the installation screen, then reboot.
