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.

Now, last I checked, I had no ISA slots on my motherboard. Why do I have an ISA bridge? Am I totally thinking of the wrong thing here? Does my mobo use the ISA bridge for other purposes?
I compiled my own 2.6.5 kernel a while back, and I disabled ISA support since I didn't think I had it.... ?
Neither do I but it is still there it is left over legacy junk in the design of the x86 computers.

Really? The reason I was asking is because I am having trouble getting my external modem to work. I plug it into the 9-pin serial port on the back of my computer, but it is not detected at all. I tried running KPPP through all the serial ports, but it just didn't find anything (/dev/modem didn't work, either). Again, I am wondering if this is because I disabled ISA support, and that somehow affected my serial port (hey, I could make that into a snappy tune: "I disabled ISA support / that affected muh serial port!", hmmm maybe I should go do some homework).

Well I know pretty much zero about modems having never had the pleasure of needing to use one in my years of linux but what little I do know is this. You need to make sure that you have not disabled the serial ports in your bios and still have the support in the kernel so they are being detected you can check with something like this.
>$ dmesg | grep tty
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
And you should see results like I have here and you want the link for the /dev/modem to link to most likely the /dev/ttyS0 the first serial port so if it does not then you would ln -sf /dev/ttyS0 /dev/modem to create the proper link. Now it being a hardware modem (or at least it should be it being an external) you do whatever you normally would to connect this is the part where I have no clue so you are on your own here. Also I believe the serial ports are separate from the ISA support so that should not matter.
I recompiled my kernel, following db's suggestions, and after troubleshooting a few more errors--fixed by a few linuxQuestion search--I was bumping along at a peppy 56k--well, you know, less than 56k, but still the internet!
As a side not, I had also been trying to get my smartPCI561 card to work, and it looked promising, with the 2.6 kernel drivers supplied by the company themselves, but I got some funny errors. A few searches essentially yealded the conclusion "give up, and use the external modem". I wish others better luck than I had with the smartPCI561. :-D
