<h3><a name="main">Boot Loader Help</a></h3>
|
|
Welcome to <em>&product;</em><br><br>
|
|
|
|
Use this menu to select the desired function. If you have
|
|
problems navigating in this help system, press
|
|
<em>F1</em> to enter the <a href="#help">description</a> of the help
|
|
system. The main functions in this menu are:<br><br>
|
|
|
|
<a href="#harddisk">Boot from Hard Disk</a>: This selection will not do
|
|
anything to the system. It only starts a previously installed
|
|
operating system.<br><br>
|
|
|
|
<a href="#linux">Installation</a>:
|
|
This installation mode works on most machines. If you experience a
|
|
system freeze during boot or problems with detection of your hardware
|
|
components, such as disk controllers or network cards, try one of the
|
|
following installation options. <br><br>
|
|
|
|
<a href="#noacpi">Installation -- ACPI Disabled</a>: Many of the
|
|
currently-sold computers have incomplete or faulty ACPI
|
|
implementations. This selection disables ACPI support in the
|
|
kernel, but still enables many performance features, like DMA for IDE
|
|
hard disks. <br><br>
|
|
|
|
<a href="#failsafe">Installation -- Safe Settings</a>: If you were not
|
|
successful with <em>Installation</em>, this selection might
|
|
solve the issue.<br><br>
|
|
|
|
<a href="#rescue">Rescue System</a>: This boot image starts a small
|
|
Linux system in RAM. This is useful if the system does not start properly.
|
|
After booting this system, log in as root. <br><br>
|
|
|
|
<a href="#memtest">Memory Test</a>: Memory testing is useful for more than
|
|
checking installation of new memory modules. It is a stress test
|
|
for a big part of your computer system and may indicate hardware
|
|
problems. <br><br>
|
|
|
|
<a href="#opt">Boot Options</a>: The boot options may change the
|
|
behavior of your system completely. They are settings for
|
|
the kernel.<br><br>

|
<a href="#help">F1 Help</a>: This is context sensitive. It will
|
|
show different screens depending on the active element of the

boot screen. There is also a description of this help system
|
|
available.<br><br>
|
|
|
|
<a href="#videomode">F2 Video Mode</a>: Here, choose between

replaces the old APM system. <br><br>
|
|
|
|
Select <em>Installation -- ACPI Disabled</em> if you encounter
|
|
problems during boot of the kernel. Known problems with machines that
|
|
have problems with ACPI are:
|
|
<br><br>
|
|
|
|
* kernel freezes when booting<br>
|
|
* PCI Cards are not detected or initialized properly<br><br>

<h3><a name="opt">Boot Options</a></h3>
|
|
|
|
There are two types of boot options available. First, there are
|
|
options that affect the installer. Second, there are kernel
|
|
options. Some of the more common options are: <br><br>
|
|
a) installer options<br>
|
|
<br>
|
|
<a href="#o_install">install</a> -- select an installation source<br>
|

b) kernel options<br>
|
|
<br>
|
|
<a href="#o_splash">splash</a> -- influence the behavior of the splash screen<br>
|

<h3><a name="o_install">Installer Options: install</a></h3>
|
|
|
|
By default, the local CD-ROMs are searched for the installation source.
|
|
For a network install, select the
|
|
<em>install</em> option. Possible installation protocols are<br>
|
|
* FTP<br>
|
|
* NFS<br>
|
|
* HTTP<br>
|
|
The syntax to use is just like standard URLs. For example,
|
|
if your server is found at 192.168.0.1 and you want to do an NFS-based
|
|
install from the directory /install on this server, specify
|
|
the source as follows:<br><br>
|
|
|
|
<em>install=nfs://192.168.0.1/install</em><br><br>
|
|
|
|
The network card will either be configured with <em>dhcp</em> or you
|
|
must specify the parameters yourself as described in the
|
|
<a href="#network">network options</a>.<br>

<h3><a name="o_splash">Kernel Options: splash</a></h3>
|
|
|
|
|
|
The splash screen is the picture shown during system start-up.<br>
|
|
<br>
|
|
<em>splash=0</em><br><br> The splash screen is switched off. This may be useful
|
|
with very old monitors or if some error occurs.<br>
|
|
<br>
|
|
<em>splash=verbose</em><br><br> Activates splash, kernel and boot messages are
|
|
still shown.<br>
|
|
<br>
|
|
<em>splash=silent</em><br><br>
|
|
Activates splash, but no messages. Instead a progress bar is drawn.<br>

|
<h3><a name="network">Installer Options: Network Options</a></h3>
|
|
|
|
It is possible to configure the network interface right now. The
|
|
hardware will be detected later by YaST2. The minimum set of options
|
|
to configure your network card consists of host IP and netmask. For
|
|
example:<br><br>
|
|
|
|
<em>hostip=192.168.0.10 netmask=255.255.255.0</em><br>
|
|
<br>
|
|
or in a shorter form:<br><br>
|
|
|
|
<em>hostip=192.168.0.10/24</em><br>
|
|
<br>
|
|
|
|
If you specified a <a href="#o_install">network-based install</a> and do
|
|
not specify both of these options, the installer tries to configure
|
|
the network interface with <em>dhcp</em>. If you need a default
|
|
gateway, specify this with the option <em>gateway</em>. For
|
|
example:<br><br>
|
|
|
|
<em>gateway=192.168.0.8</em><br>

|
To enable the VNC installation, specify the
|
|
parameters vnc and vncpassword:<br><br>
|
|
|
|
<em>vnc=1 vncpassword=example</em><br><br>

<h3><a name="o_apm">Kernel Options: apm</a></h3>
|
|
|
|
APM is one of the two power management strategies used on current
|
|
computers. It is mainly used with laptops for functions like suspend
|
|
to disk, but it may also be responsible for switching off the
|
|
computer after power down. APM relies on a correct working BIOS. If
|
|
the BIOS is broken, APM may have only limited use or even prevent the
|
|
computer from working. Therefore, it may be switched off with the
|
|
parameter<br><br>
|
|
|
|
<em>apm=off</em> -- switch off APM completely<br><br>
|
|
|
|
Some very new computers may take more advantage from the newer
|
|
<a href="#o_acpi">ACPI</a>.

|
|
<h3><a name="o_acpi">Kernel Options: acpi</a></h3>
|
|
|
|
ACPI (Advanced Configuration and Power Interface) is a
|
|
standard that defines power and configuration management interfaces
|
|
between an operating system and the BIOS. By default, <em>acpi</em> is
|
|
switched on when a BIOS is detected that is newer than from year
|
|
2000. There are several commonly
|
|
used parameters to control the behavior of ACPI:<br>
|
|
<br>
|
|
<em>pci=noacpi</em> -- do not use ACPI to route PCI interrupts
|
|
<em>acpi=oldboot</em> -- only the parts of ACPI that are relevant
|
|
for booting remain activated<br>
|
|
<em>acpi=off</em> -- switch off ACPI completely<br>
|
|
<em>acpi=force</em> -- switch on ACPI even if your BIOS is dated
|
|
before 2000<br>
|
|
<br>
|
|
Especially on new computers, it replaces the old
|
|
<a href="#o_apm">apm</a> system.

IDE is, unlike SCSI, commonly used in most desktop workstations.
|
|
To circumvent some hardware problems that occur with IDE systems, use the
