Installation Media
This section will help you determine which different media types you can use to
install &debian;. There is a whole chapter devoted to media,
, which lists the advantages and
disadvantages of each media type. You may want to refer back to this page once
you reach that section.
CD-ROM/DVD-ROM/BD-ROM
Installation from optical disc is supported for most architectures.
On PCs SATA, IDE/ATAPI, USB and SCSI optical drives are supported, as are
FireWire devices that are supported by the ohci1394 and sbp2 drivers.
USB Memory Stick
USB flash disks a.k.a. USB memory sticks have become a commonly used
and cheap storage device. Most modern computer systems also allow
booting the &d-i; from such a stick. Many modern computer systems, in
particular netbooks and thin laptops, do not have an optical drive
anymore at all and booting from USB media is the standard way of
installing a new operating system on them.
Network
The network can be used during the installation to retrieve files needed
for the installation. Whether the network is used or not depends on the
installation method you choose and your answers to certain questions that
will be asked during the installation. The installation system supports
most types of network connections (including PPPoE, but not ISDN or PPP),
via either HTTP or FTP. After the installation is completed, you can also
configure your system to use ISDN and PPP.
You can also boot the installation system over the
network without needing any local media like CDs/DVDs or USB sticks. If
you already have a netboot-infrastructure available (i.e. you are already
running DHCP and TFTP services in your network), this allows an easy and fast
deployment of a large number of machines. Setting up the necessary
infrastructure requires a certain level of technical experience, so this is
not recommended for novice users.
This is the preferred installation technique
for &arch-title;.
Diskless installation, using network booting from a local area network
and NFS-mounting of all local filesystems, is another option.
Hard Disk
Booting the installation system directly from a hard disk is another option
for many architectures. This will require some other operating system
to load the installer onto the hard disk. This method is only recommended
for special cases when no other installation method is available.
Un*x or GNU system
If you are running another Unix-like system, you could use it to install
&debian-gnu; without using the &d-i; described in the rest of this
manual. This kind of install may be useful for users with otherwise
unsupported hardware or on hosts which can't afford downtime. If you
are interested in this technique, skip to the . This installation method is only recommended
for advanced users when no other installation method is available.
Supported Storage Systems
The &debian; installer contains a kernel which is built to maximize the
number of systems it runs on.
Generally, the &debian; installation system includes support for IDE (also
known as PATA) drives, SATA and SCSI controllers and drives, USB, and
FireWire. The supported file systems include FAT, Win-32 FAT extensions
(VFAT) and NTFS.
IDE systems are also supported.
Any storage system supported by the Linux kernel is also supported by
the boot system.
Any storage system supported by the Linux kernel is also supported by
the boot system. This means that FBA and ECKD DASDs are supported with
the old Linux disk layout (ldl) and the new common S/390 disk layout (cdl).
