This article describes the booting process of SME Server.
==Installation==
When booting from the installation CD you will get a boot prompt where you can simply press Enter to start the standard installation (or upgrade) routine. On i586 (e.g. VIA C3) based machines type smei586 and press Enter.

From SME ISO releases 7.5.1 and SME 8.0beta6 the installer will automatically exclude the drive containing the install media or ks files. Refer http://forums.contribs.org/index.php/topic,46866.msg230681.html#msg230681

==General Boot Help==
Certain hardware configurations may have trouble with the automatic hardware detection done during the installation. If you experience problems during the installation, restart the installation adding the ''noprobe'' option.

==Kernel Parameter Help==
Some kernel parameters can be specified on the command line and will be passed to the kernel. This does not include options to modules such as ethernet cards or devices such as CD-ROM drives.

To pass options to modules, you will need to use the noprobe mode to disable PCI autoprobing. When the installer asks for your device type that needs an option or parameter passed to it, there will be a place to type those in at that time.

==Rescue Mode Help==
The installer includes a rescue mode which can be used when a system does not boot properly. The rescue mode includes many useful utilities (editor, hard drive and RAID tools, etc.) which will allow one to restore a system to a working state.
