Wireless networking is in general supported as well and a growing number of wireless adapters is supported by the official Linux kernel, although many of them do require firmware to be loaded. Wireless NICs that are not supported by the official Linux kernel can generally be made to work under &debian;, but are not supported during the installation.

437.

The use of wireless networking during installation is still under development and whether it will work depends on the type of adaptor and the configuration of your wireless access point. If there is no other NIC you can use during the installation, it is still possible to install &debian; using a full CD-ROM or DVD image. Select the option to not configure a network and install using only the packages available from the CD/DVD. You can then install the driver and firmware you need after the installation is completed (after the reboot) and configure your network manually.

Devices Requiring Firmware

455.

Besides the availability of a device driver, some hardware also requires so-called <firstterm>firmware</firstterm> or <firstterm>microcode</firstterm> to be loaded into the device before it can become operational. This is most common for network interface cards (especially wireless NICs), but for example some USB devices and even some hard disk controllers also require firmware.

456.

In most cases firmware is non-free according to the criteria used by the &debian; project and thus cannot be included in the main distribution or in the installation system. If the device driver itself is included in the distribution and if &debian; legally can distribute the firmware, it will often be available as a separate package from the non-free section of the archive.

457.

However, this does not mean that such hardware cannot be used during an installation. Starting with &debian; 5.0, &d-i; supports loading firmware files or packages containing firmware from a removable medium, such as a floppy disk or USB stick. See <xref linkend="loading-firmware"/> for detailed information on how to load firmware files or packages during the installation.

SCSI, SATA and IDE/ATAPI CD-ROMs are supported. The <ulink url="&url-cd-howto;">Linux CD-ROM HOWTO</ulink> contains in-depth information on using CD-ROMs with Linux.

498.

Generally, the Debian installation system includes support for floppies, IDE (also known as PATA) drives, IDE floppies, parallel port IDE devices, SATA and SCSI controllers and drives, USB, and FireWire. The supported file systems include FAT, Win-32 FAT extensions (VFAT) and NTFS.

499.

Disk interfaces that emulate the <quote>AT</quote> hard disk interface &mdash; often called MFM, RLL, IDE, or PATA &mdash; are supported. SATA and SCSI disk controllers from many different manufacturers are supported. See the <ulink url="&url-hardware-howto;">Linux Hardware Compatibility HOWTO</ulink> for more details.
