Indeholder ofte nyttig information om konfiguration eller brug af dit udstyr.
Dokumentation af S/390-specifik opstartssekvens, kommandoer og enhedsdrivere (f.eks. DASD-, XPRAM-, Console-, OSA-, HiperSockets- og z/VM-interackion)
IBM Redbook der beskriver hvordan Linux kan kombineres med z/VM på zSeries- og S/390-udstyr.
IBM Redbook der beskriver Linuxdistributionerne tilgængelige for mainframen. Bogen har ikke et afsnit om Debian, men de grundlæggende installationskoncepter er de samme på tværs af alle S/390-distributioner.
I mange tilfælde vil installationsprogrammet automatisk kunne detektere dit udstyr. Men for at være forberedt anbefaler vi at du gør dig bekendt med dit udstyr før installation.
Udstyrsinformation kan indsamles fra:
Manualerne som følger med hver stykke af udstyr.
The BIOS setup screens of your computer. You can view these screens when you start your computer by pressing a combination of keys. Check your manual for the combination. Often, it is the Delete or the F2 key, but some manufacturers use other keys or key combinations. Usually upon starting the computer there will be a message stating which key to press to enter the setup screen.

Many products work without trouble on Linux. Moreover, hardware support in Linux is improving daily. However, Linux still does not run as many different types of hardware as some operating systems.
Drivers in Linux in most cases are not written for a certain “product” or “brand” from a specific manufacturer, but for a certain hardware/chipset. Many seemingly different products/brands are based on the same hardware design; it is not uncommon that chip manufacturers provide so-called “reference designs” for products based on their chips which are then used by several different device manufacturers and sold under lots of different product or brand names.
This has advantages and disadvantages. An advantage is that a driver for one chipset works with lots of different products from different manufacturers, as long as their product is based on the same chipset. The disadvantage is that it is not always easy to see which actual chipset is used in a certain product/brand. Unfortunately sometimes device manufacturers change the hardware base of their product without changing the product name or at least the product version number, so that when having two items of the same brand/product name bought at different times, they can sometimes be based on two different chipsets and therefore use two different drivers or there might be no driver at all for one of them.
For USB and PCI/PCI-Express/ExpressCard devices, a good way to find out on which chipset they are based is to look at their device IDs. All USB/PCI/PCI-Express/ExpressCard devices have so called “vendor” and “product” IDs, and the combination of these two is usually the same for any product based on the same chipset.
On Linux systems, these IDs can be read with the lsusb command for USB devices and with the lspci -nn command for PCI/PCI-Express/ExpressCard devices. The vendor and product IDs are usually given in the form of two hexadecimal numbers, seperated by a colon, such as “1d6b:0001”.
Et eksempel på resultatet for lsusb: “Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub”, hvor 1d6b er leverandør-id'et og 0002 er produkt-id'et.
Et eksempel på uddata for lspci -nn for et Ethernetkort: “03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 06)”. Id'erne er givet inden for den højre firkantede parentes, dvs. 10ec er levereandøren - og 8168 er produkt-id'et.
Et andet eksempel, et grafikkort kan give det følgende resultat: “04:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV710 [Radeon HD 4350] [1002:954f]”.
On Windows systems, the IDs for a device can be found in the Windows device manager on the tab “details”, where the vendor ID is prefixed with VEN_ and the product ID is prefixed with DEV_. On Windows 7 systems, you have to select the property “Hardware IDs” in the device manager's details tab to actually see the IDs, as they are not displayed by default.
Searching on the internet with the vendor/product ID, “Linux” and “driver” as the search terms often results in information regarding the driver support status for a certain chipset. If a search for the vendor/product ID does not yield usable results, a search for the chip code names, which are also often provided by lsusb and lspci (“RTL8111”/“RTL8168B” in the network card example and “RV710” in the graphics card example), can help.
Debian GNU/Linux is also available as a so-called “live system” for certain architectures. A live system is a preconfigured ready-to-use system in a compressed format that can be booted and used from a read-only medium like a CD or DVD. Using it by default does not create any permanent changes on your computer. You can change user settings and install additional programs from within the live system, but all this only happens in the computer's RAM, i.e. if you turn off the computer and boot the live system again, everything is reset to its defaults. If you want to see whether your hardware is supported by Debian GNU/Linux, the easiest way is to run a Debian live system on it and try it out.
There are a few limitations in using a live system. The first is that as all changes you do within the live system must be held in your computer's RAM, this only works on systems with enough RAM to do that, so installing additional large software packages may fail due to memory constraints. Another limitation with regards to hardware compatibility testing is that the official Debian GNU/Linux live system contains only free components, i.e. there are no non-free firmware files included in it. Such non-free packages can of course be installed manually within the system, but there is no automatic detection of required firmware files like in the debian-installer
, so installation of non-free components must be done manually if needed.

Hvis din computer er forbundet til et fast netværk (dvs. et Ethernet eller en tilsvarende forbindelse — ikke en opkalds-/PPP-forbindelse) som administreres af andre, så skal du spørge dit netværkssystems administrator om denne information:
Dit værtsnavn (du kan også vælge dette på egen hånd).
Dit domænenavn.
Din computeres IP-adresse.
Netmasken at bruge med dit netværk.
IP-adressen for adgangspunktsystemet du skal vidersende til, hvis dit netværk har et adgangspunkt.
Systemet på dit netværk som du skal bruge som en DNS-server (Domain Name Service).
Hvis netværket, du er forbundet til, bruger DHCP (Dynamic Host Configuration Protocol) til at konfigurere netværksindstillinger, så skal du ikke bruge denne information, da DHCP-serveren vil angive dem direkte til din computer under installationsprocessen.
Hvis du har internetadgang via DSL eller kabelmodem (dvs. over et kabel-tv-netværk) og har en router (ofte forhåndskonfigureret af din telefon- eller catv-leverandør) som håndterer din netværksforbindelse, så er DHCP normalt tilgængelig som standard.
