Dell Inspiron 1520 – Windows 7 64 bit drivers

October 25, 2009

I have installed the new Microsoft Windows 7 64 bit on my Dell Inspiron 1520 Laptop. I can only say that it was worth installing it. Because of the lack of support from Dell (although this laptop is fully 64 bit capable), one has to find some of the drivers itself. I will list here the incompatible drivers that you need, in order for the laptop to work properly with Windows 7 64bit:

1. Missing driver for Ricoh R5C833, R5C847. Corresponding driver can be downloaded here.

2. Synaptics Touchpad / Pointing Stick driver can be downloaded here.

3. Dell Quickset program can be downloaded here.

4. The NVIDIA GeForce 8600M driver can be downloaded from this site. Just download the latest driver, and you are set to go. (Hint: This site and the drivers on it can be actually used for any NVIDIA Graphics card.)

5. If you have problems with the external microphone, or some kind of audio problem, and your audio card is: SIGMATEL STAC 92XX C-Major HD Audio, then please download the driver here.

6. Dell Wireless 355 Bluetooth Module (Bluetooth 2.0 + EDR) can be downloaded here.

7. IntelĀ® Chipset Software Installation Utility for the GM965 mobile chipset can be downloaded here.

8. IntelĀ® Rapid Storage Technology (earlier called Intel(R) Matrix Storage Manager) can be downloaded here.

I hope that this post will help others that encountered the same problems with Dell drivers on their Dell Inspiron 1520, but want to use the new Windows 7 64 bit.


Windows Vista sharing Bug – danger high!

February 19, 2008

I want to present you here what I believe it to be a bug in the Windows Vista, pressumably also in Windows XP.

In short: When you have your PC in a windows network with mixed Linux computers (tested with Ubuntu 7.10), although you don’t share your USB Flash Drive, everybody on the network can access its files, write on it, and delete them. Bug danger: very high, security risk: very high!
I will now show you through images how this bug affects your computer:

Configuration: 2 Computers in a Windows Network:

1. Windows Vista PC

2. Ubuntu 7.10 PC using the Windows network through samba.



Here you can see that the USB Flash drive isn’t shared.


The sharing setting under Windows Vista. Everything is off. No sharing of the drive.

Now we change to the Ubuntu-Linux computer.


These are the computers seen under Network (samba) in Ubuntu. The Windows computer is the second one.


On this picture you can see all the drives on the windows machine. The shared ones, and the not shared ones. Some can be still accessed, even if they are NOT shared under Windows. That is the USB Flash drive from pic 1, and 2.


Accessing the not shared USB Flash drive without any problems. You can read/write/delete files on it.


Example of creating a folder on the USB flash drive.

Now I will present the forbidden access of an external HDD connected on the windows machine, which can not be accessed through Linux, as it is expected.


Trying to access the external HDD.


Access forbidden.

This bug was found by me, and I’m presenting it here, so the people using Windows Vista can contact Microsoft, so they can solve this critical security problem. I will also contact Microsoft, and tell them about this web page, so they can do something about this problem.

I also think that this bug can be found on Windows XP, but I cannot confirm that. Somebody willing to do that, also for other Windows Editions, can try and recreate it, and report what happens.

edit: Well, I tried to find out How the hell one can report a bug to Microsoft, and found this link: It says I need to phone Microsoft??? What the hell. Spending my money on correcting Microsoft’s flaws? No thanks. Anyone willing, please do that instead of me. Thank you in advance.
