 If more partitions are going to be used (like you want to have separate /boot or /home) then these need to be mounted now, too.
-===== Network configuration =====
+===== Network configuration of RescueCD =====
-''RescueCd'' should configure (using DHCP) our network automatically during a boot process. If DHCP is not present, We need to do it manually. Let's assume We want to set IP to 192.168.0.2. **/etc/sysconfig/interfaces/ifcfg-eth0** should looks like:
+RescueCD and installed PLD system will use the same way of configuring network.
+By default both try to use DHCP to automatically configure network interface during a boot process.
+If that works for you you don't need to do anything.
+If manual configuration is required then configure networking using files below.
+==== eth0 interface configuration: /etc/sysconfig/interfaces/ifcfg-eth0 ====
+Assume you want 192.168.0.2 with /24 network (CIRD notation is preferred)
 <file>DEVICE=eth0
-IPADDR=192.168.0.2
+IPADDR=192.168.0.2/24
 ONBOOT=yes
 BOOTPROTO=none
 </file>
-In file **/etc/sysconfig/static-routes**  We added route to gateway (ex.: 10.0.0.254):
-<file>eth0 default via 10.0.0.254
+==== Default gateway and default gateway interface configuration: /etc/sysconfig/network ====

-In file **/etc/resolv.conf** we add at least one adress of DNS server:

 ==== Prepare to install kernel ====
+Before installing kernel you need to mount kernel proc, sys and dev filesystems inside of chroot:
 <file># mount -o bind /proc /pld/proc

 # mount -o bind /dev /pld/dev

+You need to tell initrd generator which hardware driver is needed to access your rootfs filesystem
+by setting scsi_hostadapter alias in **/etc/modprobe,d/modprobe.conf** (or any other file in that directory)
+<file>alias scsi_hostadapter ahci</file>
+**lspci -k** command run on rescuecd can help you to find a correct driver:

+:01.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)

+You can also install multiple different kernels.
+By default kernel installation also generates initrd based on mounted /proc, /sys, /dev files and configured fstab, modprobe.conf and few others configuration files. generated initrd (which by default is initramfs cpio image) is saved in /boot.
+If something fails or you want to regenerate initrd manually you can do it using:
+<file>/sbin/geninitrd -v -f /boot/initd-XXX-Y.gz XXX-Y</file>
+command. Real example:
+<file>/sbin/geninitrd -v -f /boot/initd-4.20.3-1.gz 4.20.3-1</file>
+//-v// option causes geninitrd to write additional information, so you can see if proper kernel modules are being installed into initrd.
+If booting with new initrd fails you can use **debuginitrd** and **debuginitrd=sh** boot kernel cmdline options to debug the problem.
