Hi.
Upon reinstallation of my windows xp home edition I have come up with some unknown devices, and one of them controls the computer recognizing my internal dial up modem. Just don't know which one.
Here is some info on unknown devices if anyone can help:

PCI Device Standard ISA Bridge: ATI technologies Device no. 438D OEM vendor Dell
PCI Device: Chipset ATI technologies Device no. 4383
PCI Device: Ricoh Co. LTD. Device 0822 OEM vendor Dell

I have tried the dell website for my service tag no., but the drivers they have there are for windows Vista and won't work on my win xp home.
Can anybody help me find correct drivers for Win xp home edition service pack 1 ?
I would love to get SP2, but I can't get the modem recognized to be able to even do dial up.
I took the internal modem out, restarted the computer twice. Then re-inserted the modem in hopes the system would recognize a new device, but it didn't work. I know the modem works, I was just using it a day ago before I had to re-install windows. I've been to driverguide.com (my favorite place) and can't seem to get any luck there either for the exact device model numbers.
Thanks,
Tina B.

You should have a a Dell Disk that says "drivers and utilities" ... If not just pull up Dell's site and pull your system up by type and model versus service tag. The drivers should be on their site.

Tina, I don't think you ever mentioned what model of Dell Inspiron you have. If the service tag takes you to Vista drivers at Dell support, then it probably had Vista pre-installed, right?

ATI was primarily a graphics chip maker, but they are now owned by AMD. They also made some motherboard chipsets and judging by the "Chipset" and "ISA Bridge" devices made by ATI you probably have such a motherboard chipset. With the chipset drivers missing, I'm surprised it boots up, but maybe it's handled in another way. The ISA bridge could be the problem if the modem is on the ISA bus. Dial-up modems are so slow, that they can easily run on the ISA bus and are very inexpensive that way.

Get a copy of CPU-Z and see if you can find the motherboard manufacturer and chipset. http://www.cpuid.com/cpuz.php

Yeah i'd say your missing graphics card drivers.
As ScottW said i'm surprised that your computer isnt having a had time without the chipset drivers.
best to go to dell for the drivers.

PS: i always find modem or lan cards drivers the hardest to find.

Hi all,
to answer the model of laptop...it's a Dell Inspiron 1521. I have no original cd that came with any drivers. This computer had Vista installed and Windows XP home put on it.
Good news is! I am actually on the net with the DELL! My LAN is now working. I have downloaded windows updates and SP2, all went fine. A couple of hotfixes too.
I still cannot get the WLAN to work. Won't connect.
I have taken care of driver issues other than the following:

PNP ID
VEN_1002&DEV_4383&SUBSYS_01FC1028&REV_00
Detected Chip Vender:ATI Technologies
Detected OEM Vender: DELL Computer Corp.

PCI standard ISA bridge
Chip: Unknown Chipset from ATI Technologies
PNP ID
VEN_1002&DEV_438D&SUBSYS_00000000&REV_00

Windows Detected Vender
(Standard system devices)

Windows Detected Device
PCI standard ISA bridge

Detected Chip Vender
ATI Technologies

What are they, and are there generic drivers somewhere that will make these work? I still do not have my internal modem being recognized and no sound as yet.
I have tried drivers for both, and nothing so far is working..even from the dell site for my pc model and OS system.
I guess I need to most of all understand what these two devices do and what they are dependent on.
Also, I was getting an error message on start up that MOM.exe could not be initialized. Now it's the following:
Could not load file or assembly 'MOM.Implementation, version 2.0.2840.38602, culture= neutral, publickey token= 90ba9c70f8467620 or one of its dependencies." The system cannot find the specified file. (Here we go again Scott, LOL)
I'm going to try to research that now, but maybe someone knows a how-to-fix.

Thanks so much!

Budo, nice linky. Dropped me right on the Dell page where I see the ATI SMBus and Ricoh chipset drivers.

Tina, MOM.exe is part of the ATI graphics adapter software. It's the Catalyst Control Center Monitor. Catalyst is what they call the drivers and software. Control Center is the software for viewing and modifying graphics setting. Try installing the latest Catalyst drivers and software for your ATI graphics chip. http://ati.amd.com/support/driver.html

I don't know what MOM.exe is monitoring. Maybe it means that Big Mother is watching you. :)

Apparently MOM.exe is a legit ATI file, but it can also be spyware.

Hi guys,
I have tried those drivers already. The one for Ricoh on the dell drivers list does not work. My PCI device is not the same model listed there. I did manage to get that one off the unkown devices using a driver that worked from Driver Guide.
The ATI driver at Dell also did not fully work, I got the catalyst control center and a couple of other items working, but is not fully functional. What I couldn't do (and didn't see) is on the catalyst software, it gives an option to search for updated drivers at AMD. I couldn't do that before due to no internet connectivity. I am now downloading the updated driver and hope it works. :-) Thanks!

OMG!!! I have sound! I have a dial up modem! I can connect with Ethernet! THIS is progress!
I'm gonna have about 6 beers before I get to that danged DELL WLAN 1390 Mini-card not connecting issue. :-)
Thanks Scott, and everyone else for pushing me in the right directions. The final piece to the puzzle, that last PCI device was Sigmatel HD audio driver. That driver included the modem driver. Dell has the wrong model number on their site for Windows XP system. I had written the numbers down when I tried to uninstall and install the dial up modem to force a recognition.
I'll keep going on the thread of "wireless connection won't connect on one home computer" as I work on that.
Thanks again,
Tina B.
