ƒ  Debian Sarge 3.1 2.6.8-3-686,  

ƒ  Debian 4.0 etch Kernel version 2.6.18-4-686,  

ƒ  Scientific Linux 4.4 Kernel version 2.6.9-11.EL) 

The following tar files exist with the driver and library compiled with the GNU gcc version shown: 

ƒ  AcqirisLinux-3.1a-gcc-3.3.tar.gz - compiled under Suse 9.2 with GNU gcc 3.3. 

ƒ  AcqirisLinux-3.1a-gcc-3.4.tar.gz - compiled under SL 4.4 with GNU gcc 3.4. 

ƒ  AcqirisLinux-3.1a-gcc-4.1.tar.gz - compiled under Debian etch with GNU gcc 4.1. 

The Kernel Driver source code is available for recompilation for users with other Linux systems. 

The appropriate tar file should be copied to a local directory (e.g. your home directory) and then unpacked by using 
the following command  

tar xzf AcqirisLinux-3.1a-gcc-X.x.tar.gz  

The resulting directory AcqirisLinux contains an install script drv-install and a graphical Demo program 
demo/AcqirisDemo.  

Before installing the driver you have to put the correct version of the Kernel mode driver into acqirisPCI.o. Type 
 cd 

AcqirisLinux/lib/modules 

and either 
 

cp acqrsPCI.o[.n] acqrsPCI.o  

 

(Linux kernel 2.4) 

or  
     cp acqrsPCI.ko[.n] acqrsPCI.ko         

(Linux kernel 2.6) 

where [.n] is the running version of the Linux kernel. This can be obtained by running the command  
 uname 

-r 

The following versions exist: 

acqrsPCI.o.2.4.21-4.EL    

for Red Hat Enterprise Linux version 3 

acqrsPCI.ko.2.6.8-3-686     

for Debian 3.1 'sarge' 

acqrsPCI.ko.2.6.8-24-smp     

for Suse 9.2 

acqrsPCI.ko.2.6.9-11.EL   

for Scientific Linux 4.4 

acqrsPCI.ko.2.6.18-4-686    

for Debian 4.0 'etch' 

To install the driver and the load script to the system, you have to get super user privileges and execute the driver 
install script by typing,  

cd AcqirisLinux 

./drv-install add 

You can check that the driver is loaded properly with lsmod or dmesg. The drv-install script has the following 
additional functionality: 

drv-install rem  to remove the driver and load script 

to restart the driver 

If you intend to use an Averager, an Analyzer, or a 12-Bit Digitizer you must install the Firmware .bit files. You can 
either copy them from the Firmware directory of the CD-ROM or download them from our WEB site. They should 
be placed in the Firmware subdirectory of AcqirisLinux. In the case of the CD-ROM, this can be done by continuing 
the above command sequence with the following: 
 

cp /mnt/CDRom/Firmware/*.bit Firmware/ 

For some special kernels, for example SMP, the kernel mode driver will have to be recompiled on the target system. 
All files needed to compile a new kernel mode driver are in AcqirisLinux/linuxdriverpci for Kernel 2.4 or in 
AcqirisLinux/linux2.6driverpci for Kernel 2.6 

The makefile can be used for compilation under a standard compatible distribution. To compile the driver, the kernel 
header files need to be installed. Furthermore, depending on the Linux distribution, the kernel source files may need 
to be installed. The makefile will try to guess where they are located. If it fails, see instructions inside the makefile 
itself to specify manually where these kernel header files are located. 

To compile a new kernel under linux-2.4, issue the following commands: 

ƒ  cd linuxdriverpci
