I am using Linux Fedora and not able to install linux drivers for WLAN. and my Kernel header is 2.6.23.1-42.fc8, The problem is i am not able to execute the 'Make KVER=2.6' command. also find the read me file below:

READ ME file:
To compile the driver sources for kernel 2.6, proceed as follows:
1. Open a root-shell.
2. Go to the directory /src/.
3. Edit the .config file:
- KVER=2.6
- for 8385, please take config-8385 as example
- for 8686, please take config-8686 as example
4. Execute the command "make KVER=2.6".
You will then find the
- bus driver in the directory ./src/release2.6/mrvlsdio.ko
- bus driver api in the directory ./src/release2.6/sdioapi.ko
- WLAN driver in the directory ./src/release2.6/sd83xx.ko

NOTE: The "make" process includes the kernel configuration
"/usr/src/linux/.config". In addition, the Linux file
rules.make is needed.

If the these files do not exist, proceed as follows:
1. Install the kernel header files.
2. Go to the directory /usr/src/.
3. Create a symbolic link that points to the kernel sources
by executing the command "ln -s <name header files> linux".
A valid configuration for your system is created.

To load the drivers, proceed as follows:
1. Open a root-shell.
2. Go to the directory /src/release2.4/ or /src/release2.6/.
3. Execute the "./up" script to load the drivers

NOTE: The "./up" script needs "FpgaConfig.xml" to get some parameters like sdio_voltage,
please refer to chapter "5.0 SDIO voltage parameter" for choosing the right value (default:3.3V)

To install the WLAN Module, proceed as follows ("ethx" is system dependent):

You haven't actually given enough information about the problem. What happens when you try to run "make KVER=2.6"? Do you get error messages and if so, what are they? Note that case is important, so you really do need to run "make KVER=2.6" and not "Make KVER=2.6".

Thank you for the reply. I am actually running the command "make KVER=2.6" and the terminal returns me with - bash: make KVER=2.6: Command not found - Do you have any solution.

Do you have gcc and the development tools installed? Put make in a root terminal and see if it responds the same way. If it is installed it should respond:

Sounds like you need to install make.

Yes i got a return as make: *** No targets specified and no makefile found. stop.
Watz the next step?
Thankz in advance

You did edit the ./config file as per instructed?

Yes, i have edited the config-8686 file.
