This guide is a general guide to XP downgrade for all HP/Compaq consumers notebook, with NO affiliation what so ever with HP.



Be sure that you use your complete Model # (section 1) or P/N (section 2) from Service Tag when checking your specs to determine correct drivers, here.



If you require more help, start a new thread in laptop forum, using full model # and P/N from Service Tag,along with drivers you have tried that work/didn't work and any features that are not functioning.





1. For Difficult Models, it is reported that using SP3 is better than SP2 (no more devcon utility)
2. Always make Vista Recovery cd/dvd before downgrade to XP. see it here
3. You have a folder with drivers & programs that may prove very helpful after XP downgrade.
Copy folder C:\Swsetup to DVD Before formatting your hdd.
4. If you have a SP2 XP cd, get the full SP3 to Integrate with Nlite: SP3, Nlite HERE







3. Difficult Models



For NEW notebook consumer models e.i. Presario, Pavilion, and HDX models are difficult to downgrade. It is possible task but needs many efforts.



Difficult models are CQ40, CQ35, CQ45, CQ61 Presario models, dv2, dv3, dv4, dv5, dv6, dv7 Pavilion models and all HDX models



Some information from XP downgraders

1. For Intel platform, some of XP downgraders have to utilize devcon utility to restart MS-UAA automatically, XP-SP3 may solve this issue.
2. HP Quick Launch Buttons software do not install proper keyboard layout that lead some Fn feature malfunctions, i.e (brightness control) a BIOS update may solve this problem, please read extra caution below and update it only while in Vista.
3. HP has released XP ENE CIR driver, download below.
4. XP driver is not available for IDT sound chip, “old” Vista driver can be used however, needs some tricks to make it work properly, using audio driver from C:\swsetup is reported solve this issue
5. HD and Blue Ray features may not run properly in XP.



Precautions to Take Before BIOS UPDATE

1. Connect the notebook to the AC power supply, exit all other programs, and allow the computer to restart after applying the updated BIOS.
2. Do not turn off the computer while the BIOS is updating. Attempting to cancel this update operation will cause damage to the BIOS and will require that the computer be repaired at an HP authorized facility.



Our recommendation is stay with Vista or wait for Windows 7; however, if you think XP is a must, dual boot would the best way for these notebooks.



SATA DRIVERS



You may use external floppy drive and use the option of F6 during windows XP installation, however if you don’t have it, use Nlite.

A good guide to slipstream sata driver (the guide only shows ICH8 sata driver) here

Nlite download: Here



Notebook with Intel processors installed, use ICH9 sata driver,

ICH9 sata driver, here

The driver is located in iaAHCI.inf and is called ICH9M-E/M SATA AHCI Controller



Notebook with AMD processors installed, use AMD sata driver.



AMD SATA AHCI Controller, here


Or, AMD SATA AHCI driver from HP , here

Extract sp43839 to a folder and use files in RAID7xx folder



Important Notes:

1. In Nlite, choose the option of insert -> multiple driver folder
2. Select ONLY x86 driver for AMD SATA AHCI when asked.
3. Never choose x64 driver when asked



For Difficult Models, reading Joshua Wood’s guide is a must before proceed to XP downgrade, here

Falls du mehr hilfe brauchst, mache einen thread im laptop forum, und sag welche treiber gefailt haben .

1. Fuer schwerere Modelle, solltest du Service Pack 3 benutzen (besser als SP2).
2. Mach eine Vista backup cd/dvd bevor du auf xp gehst.
3. Backup den ordner "C:\Swsetup" bevor du deine Harddrive formatierst.
4. Wenn du eine Service Pack 2 XP cd hast, hol dir eine SP3 cd dass Nlite funktioniert.

Fuer neue laptop benutzer modelle z.b. Presario, Pacilion, und HDX modelle is es schwer zu downgraden. Es ist zu schaffen aber braucht viele versuche.

Schwerere modelle sind CQ40, CQ35, CQ45, CQ61 Pavilion modelle und alle HDX modelle.

Einige Informationen von XP downgradern (die personen)

1. Fuer eine Intel plattform, muessen einige XP downgrader das Devcon Dienstprogramm nutzen um die MS-UAA neu zu starten. XP-ServicePack3 loest das problem vielleicht.
2. HP quick launch tasten werden die tastatur nicht richtig installieren, was fehlfunktionen aufrufen wird. Ein BIOS update wird das problem vielleicht beheben. Updaten NUR IN VISTA.
3. HP hat einen XP ENE CIR driver releast, download ist unten irgwo.
4. XP treiber gibts nicht fuer IDT sound chip. Der "alte" vista driver funktioniert aber mit ein paar tricks zum richtig funktionieren, wenn man den audio driver von C:\swsetup benutzt. Dieser soll angeblich helfen.
5. HD und Blue Ray funktionen funktionieren vielleicht nicht wenn du XP drauf hast.


Vorsichtsmaßnahmen die man beachten muss bevor man BIOS updated.
1. Schliesse den laptop an die AC stromversorgung, schliesse alle programme, und erlaube dem computer neuzustarten nach dem BIOS update.
2. Mach den pc auf keinen fall aus waehrend er BIOS updated, das zerstört deinen pc.

Unsere empfehlung ist bleib bei vista oder warte auf Win7, aber wenn du unbedingt XP willst, dual booten wird der beste weg sein fuer diese laptops.

SATA DRIVERS
Sie duerfen externe floppy laufwerke benutzen und die option von F6 bei der winXP installation benutzen. Wenn du das nicht hast, nimm Nlite.
Ein guter guide zum sata driver slipstreamen hier -> *link*

Laptops die intel prozessoren installiert haben, brauchen ICH9 sata treiber, link hier -> *link*
Der treiber ist in iaAHCI.inf und ist "ICH9M-E/M SATA AHCI Controller" genannt.
Laptops die einen AMD prozessor benutzen, brauchen einen AMD sata treiber
Oder, AMD SATA AHCI driver von HP, hier *link*
Entpacke sp43839 in einen ordner und benutze die dateien im RAID7xx ordner.

Wichtige Anmerkungen:
1. In Nlite, waehle die option "Insert" (einfuegen) -> multiple driver folder (multipler treiber ordner)
2. Waehle NUR x86 driver fuer AMD SATA AHCI wenn du danach gefragt wirst.
3. Waehle NIEMALS x64 wenn du danach gefragt wirst.

Fuer schwierige modelle, solltest du Joshua Wood's guide lesen bevor du downgradest *link*

CHIPSET TREIBER

Laptops mit AMD prozessoren muessen AMD chipset zuerst installieren
Installiere .NET framework jetzt. *link*
Downloade South Bridge Driver, *link*
Laptops mit INTEL prozessoren muessen Intel chipset zuerst installieren.
Intel chipset (installieren + neustarten dann) *link*

Einige notizen:

1. Falls du Intel Video Graphic hast, musst du MS-UAA installiert haben bevor du den Intel video graphic driver installierst.
2. Neue Nvidia treiber (185.85) braucht auch MS-UAA fuer den HDMI treiber.
3. Falls du ATI video Graphic hast, musst du MS-UAA installiert haben bevor du Intel video graphic driver installierst.
4. Ein neustart ist benoetigt bevor du die Audio und Modem treiber installierst.
5. MS-UAA, sp33867, ist eigentlich kb888111 mit anderen schnellen reparaturen fuer XP.
6. Falls du XP-ServicePack3 benutzt, versuche kb835221 (Aeltere version von MS-UAA) oder versuche die registry tricks.

MS-UAA *link*(sp33867) oder hier *link*(kb835221) oder das neuere *link*(sp42126)


AUDIO TREIBER

(Der schwerste treiber)

Bitte stelle sicher dass MS-UAA richtig installiert wurde.

Wie?

Geh zu

AUDIO DRIVERS

(The most difficult driver)

Please make sure MS-UAA has been installed properly

How?

Geh in Geräte-Manager unter SystemGeräte um zu sehen ob MS-UAA richtig installiert ist.
Dort sollte ein fund fuer Microsoft UAA Bus Driver for High Definition Audio sein.
Wenn nicht, dann sollte dort ein PCI mit gelb sein.

Rechtsklick auf den treiber und waehle "Update treiber"
Nein zu verbinden, Nein zu suchen, und zuletzt druecke "Automatisch installieren".
