7.4.3 Populating the Ramdisk

Create an initrd directory structure to be used for the ramdisk. For this example, the initrd

directory structure is shown below:

# ls ${INITRD}

bin ccore dev etc linuxrc mnt modules proc sbin share var

Copy the BusyBox files:

# cp -a ${BUSYBOX}/_install/bin/* ${INITRD}/bin

# cp -a ${BUSYBOX}/_install/sbin/* ${INITRD}/sbin

Copy insmod from modutils:

# cp ${MODUTILS}/insmod/insmod.static ${INITRD}/bin/insmod

Copy the firmware and loading tools:

# cp ${AMSO1100}/verbatim/fw/boot ${INITRD}/ccore/ccos.boot

# cp ${AMSO1100}/verbatim/release/fw/boot_image ${INITRD}/ccore/ccos.bin

# cp ${AMSO1100}/verbatim/release/fw/boot_image_start \

${INITRD}/ccore/ccos.bin_start

Copy the AMSO1100 host device driver. This driver module must be built against the kernel

that will be PXE booted.

# cp ${AMSO1100}/software/host/linux/sys/devccil/obj_\

`uname -r`_release/ccil.o ${INITRD}/modules/net/

Depending on your kernel configuration, you may need to copy additional drivers to the

ramdisk. These drivers can be found in /lib/modules/`uname -r`/kernel/

With most RedHat installations we needed drivers to support NFS. The modules we needed

were sunrpc.{o,ko}, lockd.{o,ko}, and nfs.{o,ko}. They should be installed in

${INITRD}/modules/net/.

With most SuSE installations we needed drivers for Raw Socket support. The module we

needed was af_packet.{o,ko}. This module is installed in

${INITRD}/modules/net/.

Edit ${INITRD}/linuxrc accordingly (see below for some detail).

Example 1 [for RHEL 3, 2.4.21-15.ELsmp]:

# load the drivers

insmod /modules/net/sunrpc.o

insmod /modules/net/lockd.o

insmod /modules/net/nfs.o

insmod /modules/net/ccil.o

Example 2 [for SuSE 9, 2.4.21-102-smp]:

# load the drivers

insmod /modules/net/af_packet.o
