8 Red Hat Boot Diskette Modification Process
1. Copy the Network Boot Diskette (bootnet.img) and Supplemental Driver Diskette (drvnet.img) files
from the installation media (CD or ISO) to a temporary staging area.
# cp /mnt/cdrom/images/{bootnet.img,drvnet.img} .
# ls
bootnet.img drvnet.img
2. Create the temporary mount point and two module directories.
# mkdir -p mnt/{boot,drv,initrd}
# ls mnt
boot drv initrd
# mkdir modules-boot modules-drv
# ls
bootnet.img drvnet.img mnt modules-boot modules-drv
3. Mount the bootnet.img file via the loopback device
# mount -o loop bootnet.img mnt/boot
# ls mnt/boot
boot.msg general.msg ldlinux.sys rescue.msg vmlinuz
expert.msg initrd.img param.msg syslinux.cfg
4. Uncompress the initrd.img file to the staging area.
# gunzip -c < mnt/boot/initrd.img > tmp.img
# ls
bootnet.img drvnet.img mnt modules-boot modules-drv tmp.img
5. Mount the uncompressed initrd.img file (tmp.img) via the loopback device.
# mount -o loop tmp.img mnt/initrd
# ls mnt/initrd
bin dev etc linuxrc lost+found modules proc
sbin tmp var
# ls mnt/initrd/modules
module-info modules.cgz modules.dep pcitable
6. Mount the drvnet.img file via the loopback device.
# mount -o loop drvnet.img mnt/drv/
7. Extract the driver modules from the archive stored in the initrd.img file to the first module directory
created in step #2 (modules-boot).
# cd modules-boot
# gunzip -c < ../mnt/initrd/modules/modules.cgz | cpio –id
1412 blocks
# ls
2.4.9-e.40BOOT
# ls 2.4.9-e.40BOOT/
3c59x.o hid.o lockd.o scsi_mod.o usb-ohci.o vfat.o
eepro100.o input.o nfs.o sunrpc.o usb-storage.o
fat.o keybdev.o pcnet32.o usbcore.o usb-uhci.o
# cd ..
8. Extract the driver modules from the archive stored in the drvnet.img file to the second module
directory created in step #2 (modules-drv).
# cd modules-drv
# gunzip -c < ../mnt/drv/modules.cgz | cpio –id
