1. Download and decompress the driver
2. In the src directory edit the Makefile
3. In the header of the Makefile turn off iANS and PRODIAG
4. Close & save the Makefile
5. make clean
6. make CFLAGS_EXTRA="-D__BOOT_KERNEL_BOOT=1 -D__BOOT_KERNEL_SMP=0 -D__BOOT_KERNEL_BIGMEM=0 -D__BOOT_KERNEL_UP=0"

   This should compile the driver for the Redhat BOOT kernel (e1000.o)

Part B: Unzip and mount the image you wish to modify:

1. Locate the initrd ramdisk image you wish to modify
2. gzip -dc initrd.img> /tmp/initrd.ext2
3. mkdir /mnt/initrd
4. mount -o loop /tmp/initrd.ext2 Z

Part C: Decompress the modules.

1. gzip -dc /mnt/initrd/modules/modules.cgz >/tmp/modules.cpio
2. cd /tmp
3. zcat /tmp/modules.cpio | cpio -ivd
4. Copy the e1000.o into the directory created by the last command
5. cd /tmp (if you left)
6. find (directory created by cpio)/ | cpio -ov -H crc | gzip > modules.cgz
7. cp /tmp/modules.cgz /mnt/initrd/modules (and replace existing)

Part D: Add new driver info to modules and recompress the image

1. cd /mnt/initrd/modules
2. edit module-info and copy the pro100 lines modifying them for the e1000.o module
3. Add the new device ID's to the file called pcitable to support auto-detection of drivers (otherwise you will need to manually select the correct driver from the client during install)
4. leave the /mnt/initrd directory structure
5. umount /mnt/initrd
6. gzip -9 /tmp/initrd.ext2
7. mv /tmp/initrd.ext2.gz /tmp/initrd.img

You can now use the image in the /tmp directory.
