Error 104-unsupported wireless network device detected, system halted, remove device and restart
The next question is: How to fix it?
(The following procedure will help you to get a valid bios for Intel Presario R3000 not AMD Presario R3000)
A lot of post in forums, talk about this issue as a white list of manufacturers and devices that are able to work with Compaq Presario R3000 Series. (Also with other HP & Compaq models happens the same thing, but this page is only for R3000 Series). In fact it works as a white list, but this procedure is an issue related to FCC and Patents. But this problem only applies in USA, so it shouldn't be a problem in Europe, but it is. Due to manufacturing process there are no big differences if you buy a Compaq Presario R3000 in Europe or USA, in fact you can use the same internation support.
There are 3 different models
There are 3 different models of Presario R3000 series based on Video Card.
First one model, uses BIOS file with extension .uma which means Unified Memory Architecture. This model shares system memory for VGA memory card.
Second one uses BIOS file with extension identified as .m9x and, in this case VGA Card is based on ATI Mobility Radeon 9000 and 9200 Series with 64 Mb built-in and independent of system memory.
Last one uses BIOS file with extension identified as .m10, and owns ATI Mobility Raden 9600 Series
When you request us the customized BIOS firmware, you'll receive an email with 3 links. Get your right file an rename it into bios.wph and put it in the Winphlash folder. Run Winphlash.
So, what to do to plug any MiniPCI Wireless Card?
First you've got in mind is where is the MiniPCI slot located, but we guess if you arrive here you know it very well, because if you've got this problem, it is because you've plugged a miniPCI wireless card.

Anyway we'll say miniPCI socket is located behind the keyboard, and not in the back of the laptop, as other pieces like, memory slot, or hard drive. Even behind the keyboard there is one more memory slot.
So, following the procedure STEP by STEP.
Next of your questions will be, how can I follow any procedure with the miniPCI, if I'm not able at least to boot up on POST (Bios Startup)?
The answer is easy, because we'll plug miniPCI wireless card after POST. So, remove your miniPCI Wireless Card, and keep the keyboard unmounted to have easy access to miniPCI slot and restart your computer as usual. Once your Operating System has finished to load, force computer to suspend, closing the screen. Be sure, for example in Windows, in Energy Configuration, the operation related to close your screen is suspend mode.
After some seconds, your computer is in stand by mode. Open the screen. Now plug miniPCI Wireless Card, and be careful not touch any key or mousepad. Once card plugged, touch any key to power on latop again. Now do right click on My PC icon and select Properties, and click in Device Manager. Right click on any device from the list and select Search for New Hardware changes. Your miniPCI wireless card will be detected. Set it up as the manufacturer says using their own drivers or windows drivers. When procedure is finished, and windows says your hardware is ready to work back to Device Manager, look for the new item in networking devices and right click to select Properties on it. In the new window, in the top of it look for Detail page, and click on it. Ok now we're looking for the most important information we need to generate your own customized BIOS for your device. This information is Vendor ID, Device ID and Subsystem.
