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
