Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I recently installed mepis linux 06/2004 release on a Compaq Deskpro computer. After installing neither the the network card nor the modem would work. I tried swapping network cards and modems with no change. While watching the boot-up, I noticed an error message that said, " PCI: Address space collision at region 7 of bridge 0000:00:14.3 [f800:f83f] ." Does anyone know what this means, and a possible way to fix it? I took all the pci devices out except the agp video card, and it still gives the error. It also has a habbit of blacking out the monitor for a second every once in a while. Any help is greatly appreciated. I know very little about linux or programming.
The most likely cause for the network card/modem not working is that there is no driver loaded. You need to get the details of the hardware. If the modem is internal then it is likely to be a winmodem. You also need to examine either your /var/log/messages or syslog to see if it is attempting to initialise the cards. if there is no sign that the cards are being initialised in the boot process then it is almost certainly the fact there are no drivers. You would then have to do some searching for what drivers are needed for the hardware. In most instances the driver is available in the kernel as a module and just needs to be installed. Come back with info on these issues and we can probably help further.
The network cards I tried were a 3com 3C905-TX and a Network Everywhere NC100. During boot-up it would load a driver, but initialization always came up as failed. For the 3com it was loading the 3C59x driver, and for the other card it was using the Tulip driver. The modems I tried were a PCTel PCT 789T-C, and an Atech ATS-256. I figured the PCI error might be the cause, but if I can get them working without fixing the PCI problem then that would be fine too.
If the driver is loaded then you need to configure the network settings. Your distro should have details about either allocating a static address or dhcp. The modem is a winmodem so you will have to search for the driver which will either be packaged for your distro or you may have to get the source file and compile it against your kernel. My opinion of winmodems is very low and you are better advised to go out and buy an external serial modem. Avoid the usb type. The external modems are very cheap now and work without any fuss at all.
I've been looking into getting an external modem, and completely agree that winmodems aren't very good. I will continue to tinker with the network card problem. In the mean time any ideas on the error message I mentioned in the first message? Seems kind of weird that I would get that error with no cards in the machine unless it has a problem with the video card or motherboard itself. Any idea what region 7 of the bridge is, and why there would be an address collision there? I'm reasonably good with hardware, but that's a new one on me.
I did a Google search and this seems to be a kernel bug. You don't say which kernel version you are using but there are reports of this happening 2.6.8 versions. The only suggestion I can make at this stage is to make sure you have pnp turned off in the bios. If that does not rectify it try a newer kernel and if it is still occurring log a bug report.
Thanks for the effort you have been putting forward to help a newbie. The version I'm using is U.S. kernel version 2.6.7 according to the boot-up screen. There is a newer version, but I've been reluctant to download it, because with dial up it will take about a day and a half to download. I started to download it and it was giving me an estimate of 32 hours for the dl. Maybe I'll try to get one of my friends with DSL to download it for me and burn it on a cd. Again I very much appreciate the help and will post again after I get the newer version to let you know how it goes.
