Glenn,
Below are the instructions I use for adding a network module to the
bootnet.img in Redhat 7.1. I have made the instructions based on
previous postings to this list plus my own experiences. Hopefully
the instructions will prove useful even though they are for RH 7.1.
Set up
1. Make the following directories:
/tmp/boot
/tmp/boot/custom_img
/tmp/boot/initrd_img
/tmp/boot/modules
2. Copy the bootnet.img to /tmp/boot. Bootnet.img can be grabbed from
CVS or RedHat CD #1.
3. Rename the bootnet.img to custom.img
Mount and decompress the files from the boot image
1. Move into the working directory
cd /tmp/boot
2. Mount the custom.img as a filesystem mount
mount -o loop custom.img custom_img
3. Decompress
gzip -dc custom_img/initrd.img > initrd.ext2
4. Mount initrd.ext2 as a filesystem mount
mount -o loop initrd.ext2 initrd_img
5. Get the modules
gzip -dc initrd_img/modules/modules.cgz >modules.cpio
6. Extract the cpio archive
cd /tmp/boot/modules
cpio -idumv < /tmp/boot/modules.cpio
Get the new modules in place
1. Copy the new modules (*.o) to /tmp/boot/modules/2.4.2-2BOOT
2. Remove unwanted modules in /tmp/boot/modules/2.4.2-2BOOT to free up
some space
3. Edit /tmp/boot/initrd_img/modules/module-info Remove the old modules
and enter info for new modules
4. Edit /tmp/boot/initrd_img/modules/modules.dep Update with new
dependencies
5. Edit /tmp/boot/initrd_img/modules/pcitable Update with new hardware
Rebuild the boot image
1. Get into the modules directory
cd /tmp/boot/modules
2. Create new modules.cpio file
find 2.4.2-2BOOT -print -depth |cpio -H crc -ovF modules.cpio 2>
/dev/null
3. Compress the file
gzip -S .cgz modules.cpio
4. Remove the old modules.cgz
rm /tmp/boot/initrd_img/modules/modules.cgz
5. Move the new modules file into place
mv modules.cpio.cgz /tmp/boot/initrd_img/modules/modules.cgz
6. Get into the boot directory
cd /tmp/boot/initrd_img
7. This is an important step if the floppy is full. The ext2 partition
has junk left over from the removed files. It will not compress and
fit on the floppy without zeroing unused bits to improve compression
ratio. You will get an error that says "No Space Left on Device" --
just continue on.
touch zerofile
cat /dev/zero > zerofile
rm -f zerofile
8. Move directories again
cd /tmp/boot
9. Unmount the initrd filesystem
umount initrd_img
10. Recompress it
gzip initrd.ext2
11. Remove old initrd.img
rm custom_img/initrd.img
12. Place new initrd on boot image
mv initrd.ext2.gz custom_img/initrd.img
13. Remove unneeded *.msg files from /tmp/boot/custom_img to free
up some space.
14. Unmount the bootnet filesystem
umount custom_img

Hi All,
I am using Redhat 8.0 with a custom ks.cfg file to load many servers. The
new servers I have use a new (different) Ethernet card (Broadcom 5700). The
standard RedHat 8 doesn't support this card out of the box. I was wondering
if there is documentation on adding that module (bcm5700.o) as well as
updating the files (pcitable?) in the initrd.img and recreating it so it
will find the card.
Any help would be great, thanks
Glenn MacGregor
