RedHat 7.x (and Enterprise Edition) Installation Notes for the 
Intel (R) PRO/100 and PRO/1000 family of network adapters.


This README applies to RedHat* 7.0 only and addresses 2 areas: Basic compiling of all 3 Intel nic drivers on the RedHat 7 distribution 
and Enterprise Edition kernel source matching.

I. For RedHat 7 (only) installation of Intel's e100, e1000, and iANS drivers, please ensure the following are installed:
 - C libraries
 - Kernel source package (REQUIRED)
 - Specific symlinks (due to RedHat directory structure changes)
 - kgcc (because in the make file you should use cc=kgcc (instead of cc=gcc)
      

Here is a step by step method for insuring a compile ready system:
   
Install kgcc.
 Steps: Mount the install CD-Rom and change to  /Redhat/RPMS/ 
        Type  
            rpm -i kgcc-1.1.2-40.i386.rpm
      To make sure kgcc is installed, you can use the commands
            rpm -q kgcc     and     rpm -q kernel-source

Save the old include files:
   mv  /usr/include/linux  /usr/include/linux.original      
   mv  /usr/include/asm   /usr/include/asm.original 

Link the new include files
   ln  -s  /usr/src/include/linux  /usr/include/linux            
   ln  -s  /usr/src/include/asm   /usr/include/asm    
     
Link the man pages to their former location
   ln  -s  /usr/share/man  /usr/man            

Then change to the Linux source directory:
   cd  /usr/src/linux

Confirm that the kernel you are running was compiled using the source 
in  /usr/src/linux. Your kernel source should be in a directory /usr/src/<kernelversion> 

Ensure two symlinks
   /usr/src/linux pointing to <kernel version>
   /usr/include/linux pointing to ../src/linux/include/linux 

Clean up version.h 
   make mrproper     

Match running kernel                                      
   make oldconfig                                                         

Create good version.h file
   make dep                                                                  
Build the driver using kgcc  



II. The Enterprise Version - this version was built using extra patches and hence doesn't match the kernel-RPM installed source. You must install the patches from the kernel SRPM and apply them to the source to recreate the proper source tree. 

The procedure to recreate the 2.2.16-22enterprise kernel source is as follows:

1) install kernel-2.2.16-22.src.rpm and kernel-source-2.2.16-22.i386.rpm

2) make a copy of the source tree installed from kernel-source-2.2.16-22.i386.rpm

3) apply the following patches from the kernel SRPM to the new kernel source tree
	/usr/src/redhat/SOURCES/linux-2.2.16-lfs.patch
	/usr/src/redhat/SOURCES/linux-2.2.16-lfs-bigmem.patch

The patches will not install cleanly, but you can ignore the failures.

4) clean out the kernel source tree and reconfigure for the enterprise kernel
	make mrproper
	cp configs/kernel-2.2.16-i686-enterprise.config .config
	make oldconfig
	make dep

Ensure /usr/src/linux is a symlink pointing to the new enterprise kernel source, and in the Makefile change "CC=gcc" to "CC=kgcc"
