I recently encountered a problem where a Dell Inspiron 6400 displayed three base system devices after installing Windows XP onto the machine. It originally had Vista installed, so I only had Vista drivers, which didn’t work with Window XP.
About a year ago, someone I know purchased an Inspiron 6400 laptop from Dell and tried to get XP installed on it instead of Vista. They had no luck and ended up with Vista. Recently, they have decided to remove Vista and install XP on that same laptop, and asked me to do it. No problem, at least until I ended up with three devices that weren’t recognized by XP.
If you have an Inspiron 6400 and have noticed three base system devices in the device manager, then I will explain how to correct that issue in this post.

Hardware and Windows XP
As I mentioned above, I recently was tasked with installing Windows XP on a Dell Inspiron 6400 that once had Vista installed. The one problem I encountered was that all the hardware installed was new, so XP didn’t have any drivers included.

I went onto the Dell support Web site and downloaded the drivers to the local hard drive. I installed the chipset, video, sound, network adapter and wireless drivers without any issues. After I rebooted I noticed that I still had three unknown devices in the device manager.
Unknown devices in the device manager means that I still need to install some drivers. Unfortunately, the devices were listed as a “Base System Device”, so it wasn’t very descriptive to help determine what I was missing.
After a quick search on the Internet, I read that there was an additional set of drivers for the card reader that was included in the laptop.
I went to the Dell support site once again and expanded the “Chipset” drivers. One of the items in the list was called “Ricoh – Driver”, which I promptly downloaded and installed. After installing the drivers I checked the device manager and noticed that the three unknown devices were now gone. I also had three new card reader devices installed, which were the three unknown devices.
As a side note the Dell Inspiron 6400 is also known as the E1505.
Summary
After installing XP on a Dell Inspiron 6400 I noticed that there were three unknown “Base System Device” entries in the device manager. After some quick research I learned that these devices were the Ricoh card readers. I downloaded the driver from the Dell support Web site and the three unknown devices disappeared and were replaced by the actual devices.

Just redid my Inspiron and noticed that the OS CD that came with it only had 3 drivers (Audio, LAN and Chipset) so I had to download the rest.
I installed everything I could find but for the past 2 weeks I’ve been struggling with those 3 Base System Devices to the point where I almost threw my laptop out.
Then I found you… thanks for introducing me to Ricoh.
You Sir, are a godsend…

Brilliant, easy fix, many thanks
Just leaves you wondering why the hell does the Dell install process / CDs not do this, pretty okay with Dell in general, but this is poor, cheers
on September 8, 2009 at 9:57 am
I tried the CDs but they contained only the Vista drivers, and they weren’t very well laid out so finding any useful information on the CDs was a waste of time. It was much easier to go online, enter the service tag and get the XP drivers.
on September 24, 2009 at 2:51 pm
Thanks very nice….. Its yes worked

Followed your directions and there it was on the dell website:

No problem.
on September 14, 2010 at 2:18 am
Nice work. You don’t happen to have a solution for the ‘screen flicker/screen goes very dark when disconnecting the A/C and switching to battery power issue’ as well do you…?
on September 14, 2010 at 8:10 am
That would probably be the power management options of your laptop. It is common for the screen to darken when switch to battery power. I wrote a post about it with regards to Microsoft Vista here: Vista Power Saving Settings – Increase Laptop Battery Life.
If you can’t control the screen brightness while on battery power, it could be a hardware issue.
on September 14, 2010 at 4:16 pm
Yeah, I’m thinking its hardware. Machine runs fine on A/C but as soon as you pull it, the screen just goes really dark i.e. you can just make out the desktop contents. I’ve set brightness through BIOS and the only way to get the screen back is to plug it back in then close and reopen the lid. Battery management says that the battery is fine but might see if I can find a spare and test it. If its not the battery and all the software settings appear right then it would have to be hardware – just noticed that there’s a buzzing sound coming from it too which can’t be good. Just odd that if its a screen issue then why is it only doing it whilst on battery power? :S Thanks for the reply btw.
on September 15, 2010 at 3:30 pm
wow cheers!
thanks for saving me a lot of time!!
on September 15, 2010 at 4:00 pm
Turns out it was the battery… swapped it with another machine and its fine.
on September 15, 2010 at 7:24 pm
That makes sense. The LCD is the largest drain on your battery. Since you battery had an issue, it probably couldn’t provide enough power to your LCD. I’m glad you were able to find the problem.
on September 18, 2010 at 1:22 pm
splendid.. the ricoh driver for windows vista did the trick.. thanks!
on September 22, 2010 at 10:38 am
I’m glad I could help with your driver situation.
