How to add raid drivers in windows xp to Install windows xp f6 without floppy

I have been struggling to install a windows xp on a raid array.
In most cases windows does not have included drivers for ahci/raid controller will not detect no storage device and you will get a blue screen with stop code : 0x0000007B 

To solve this problem you can press F6 when the install starts but xp only accepts floppy disks that are absolute. You could buy one if you want, and better get some new floppy disks as well, as I once tried for one hour to write some drivers on some old floppy disks I had lying around.

The other way to do it is like this :
1. Extract an xp home or professional 32 or 64 whatever you need to install to a folder.
2. Download nLite and install it

    - open nLite and select the folder where you extracted the windows image and press next
    - on the next screen with preset just press next without doing nothing
    - on the next screen select/activate Drivers and Bootable ISO and press next

    - on next screen press the Insert button and select multiple driver folder - and when you are provided with a list of drivers select them all - if you have more folders or you are not sure witch are the good ones just select again Insert - multiple driver and add more

- press next to start the process and then Make ISO button

Write the image to a cd and you not get the blue screen and be provided with the install menu.

Bluetooth handsfree / headsets with caller id on android or iphone

To be able to hear caller name in you bluetooth headset it must support the bluetooth protocol PBAP or Phone Book Access Profile - aka caller announce feature.

Plantronics has 3 headsets that offer this feature : Voyager Legend, Voyager Legend UC (B235/B235-M), Voyager Edge.

From Jabra : JABRA EXTREME2

If your headset does not support the protocol no play-store app will help you - I tries dozens of them.

Other bluetooth headset protocols are :

• A2DP (Advanced Audio Distribution Profile):you can listen to audio from the phone (music, gps indications, youtube etc)
• HFP (Hands Free Profile) : you can redial last number and activate voice dialing
• AVRCP (Audio/Video Remote Control Profile) : control audio from device : stop, play, forward, backwards etc

Install windows from a network location

First create a win pe image and either set up a pxe boot server or just boot from dvd or usb.

You will end up with a cmd prompt :

Map the location where you have the windows image :

net use n: \\networkpc\sharename passwords /user:username
cd n:\windows7
