port parallèle + imprimante

ferberber · 22 janv. 2009

Je me suis monté un PC avec une carte mère INTEL DP45SG.
Cette carte n'étant pas équipée d'un port parallèle, j'ai alors ajouté une carte PCI-e pour avoir un port parallèle et ainsi pouvoir connecter mon imprimante.
Pour configurer l'imprimante j'ai fait: SYSTEME>ADMINISTRATION>IMPRESSION puis NOUVEAU.
S'ouvre alors la fenêtre de selection de périphérique mais je trouve pas de port parallèle à sélectionner !

En faisant lspci :

Il me semble que le port parallèle est bien présent!
Comment en être certain?
Comment faire pour avoir le port parallèle dans la fenêtre de sélection de périphérique?
Merci de pouvoir m'AIGUILLER !

pmarion · 22 janv. 2009

Peux-tu faire :
lspci -v -s 03:00.2
pour avoir plus de détail sur la carte et son driver.

Autre question bête :
Est-ce que ton imprimante est bien branchée en parallèle et sous tension lors du boot ?

ferberber · 22 janv. 2009

L'imprimante n'était pas connectée, je l'ai fait mis sous tension et rebooté le PC mais rien n'a évolué.
Le résultat de la commande: lspci -v -s 03:00.2

[fernando@ordiberber ~]$

Il semblerait que j'ai un "access denied" ...

ferberber · 24 janv. 2009

...en root peut-être !

non-prefetchable signifirait que des adresses mémoire n'ont pas été attribuées ?
comment je peux savoir si ma carte est reconnue ou pas ?
:hammer:

pmarion · 25 janv. 2009

La carte est reconnue, et l'IRQ 11 lui est attribuée .
l'IRQ 11 est-elle déjà utilisée ?
dmesg | grep -i irq
et
cat /proc/interrupts

Cette carte est-elle paramétrable ?

ferberber · 25 janv. 2009

Bonjour....aujourd'hui il fait beau !
J'ai à nouveau l'électricité pas encore l'eau et mon port parallèle...ça va venir 🙂

La carte ne posède aucun switch ou bien jumper de configuration...

pmarion · 25 janv. 2009

Peux-tu essayer de booter avec la ou les options
noapic
acpi=off

ferberber · 25 janv. 2009

ups...Je trouve où ces options.

pmarion · 25 janv. 2009

Il faut ajouter ces options au moment du boot (menu grub).
Normalement ce menu apparait avec une liste des différents noyaux (kernel) fedora (et autres ...) .
Si ce menu apparait pendant une certaine durée (cinq secondes?) tu peux utiliser la touche <e> (sans validation) pour intervenir et ajouter des options.
Si ce menu n'apparait pas c'est que la durée est paramétrée au minimum et il te faut utiliser la touche <ESC> pour interrompre le démarrage automatique et cela avant que le boot ne démarre.

Pour ajouter une/des options il suffit de se positionner sur une ligne de boot
Puis utiliser la touche <e> sur la première ligne .
Ceci doit afficher les trois lignes définissant un boot.
Se positionner sur la ligne «kernel ........»
Utiliser la touche <e>
Se positionner en fin de ligne pour ajouter
noapic
acpi=off
Comme le clavier est par défaut un qwerty tu devra saisir
noqpic
qcpi=off
Valider par la touche <entrée>
Puis utiliser la touche <b> pour booter avec les options spécifiées.

Si cela améliore la détection de la carte, on pourra modifier grub pour prise en compte permanente des options.

ferberber · 25 janv. 2009

J'ai ajouté à la fin de la ligne du kernel noapic acpi=off
puis <entrée> puis <b>

Au démarrage j'ai un message: " Your system had a kernel failure"
