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.

482.

IDE/ATAPI CD-ROMs are supported on all ARM machines.

On SGI machines, booting from CD-ROM requires a SCSI CD-ROM drive capable of working with a logical blocksize of 512 bytes. Many of the SCSI CD-ROM drives sold on the PC market do not have this capability. If your CD-ROM drive has a jumper labeled <quote>Unix/PC</quote> or <quote>512/2048</quote>, place it in the <quote>Unix</quote> or <quote>512</quote> position. To start the install, simply choose the <quote>System installation</quote> entry in the firmware. The Broadcom BCM91250A supports standard IDE devices, including CD-ROM drives, but CD images for this platform are currently not provided because the firmware doesn't recognize CD drives. In order to install Debian on an Broadcom BCM91480B evaluation board, you need an PCI IDE, SATA or SCSI card.

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.

You must have at least &minimum-memory; of memory and &minimum-fs-size; of hard disk space to perform a normal installation. Note that these are fairly minimal numbers. For more realistic figures, see <xref linkend="minimum-hardware-reqts"/>.

Installation on systems with less memory<footnote condition="gtk"> <para> Installation images that support the graphical installer require more memory than images that support only the textual installer and should not be used on systems with less than &minimum-memory; of memory. If there is a choice between booting the regular and the graphical installer, the former should be selected. </para> </footnote> or disk space available may be possible but is only advised for experienced users.
