11Type the following commands to complete the driver installation:

For Debian 32-bit:

cp -f /AACRAID/aacraid.ko-POST_MOD /target/lib/modules/2.6.26-2-686/kernel/ drivers/scsi/aacraid/aacraid.ko

chroot /target /sbin/depmod -a 2.6.26-2-686 update-initramfs -u -v

exit

For Debian 64-bit:

cp -f /AACRAID/aacraid.ko /target/lib/modules/2.6.26-2-amd64/kernel/drivers/ scsi/aacraid/aacraid.ko

chroot /target

/sbin/depmod -a 2.6.26-2-amd64 update-initramfs -u -v

exit

12Press CTRL+ALT+F5 to switch back to the installation screen, then reboot.

Installing with Ubuntu Linux

Note: You will need your Ubuntu Installation CD and a USB flash drive to complete this task. You must have root privileges to install the driver image.

To install the Adaptec RAID controller driver while installing Ubuntu Linux:

1Create the driver disk:

aInsert and mount the Adaptec Installation DVD:

mount /dev/cdrom /mnt/cdrom

bInsert and mount a USB flash drive:

mount /dev/sda1 /mnt/aacraid-driver

cChange to the Linux driver directory on the Adaptec Installation DVD, locate the .tgz archive file for your Ubuntu operating system version (32-bit or 64-bit), then extract the contents of the archive to a temporary location.

dCopy the contents of the archive to the USB drive by typing this command:

cp /<tempdir>/* /mnt/aacraid-driver

where tempdir is the temporary location of the driver files.

eUnmount and remove the Adaptec Installation DVD and the USB drive.

2Insert the Ubuntu Installation CD, then restart your computer.

3When the Welcome screen appears, select Install Ubuntu Server, then type CTRL+ALT+F2 to switch to the console.

4Insert the USB drive, then type the following command to scan for the device:

fdisk -l

Note: The following steps assume that the USB drive is assigned to /dev/sda1.
