1.8 Why don't you distribute binaries?

For me, distributing binaries would be a significant hassle. It is complicated because some features can only

be selected at compile time, and because the modules are somewhat dependent on having the ``right'' kernel

configuration. So, I would probably need to distribute precompiled modules along with matching kernels.

Beyond this, the greatest need for precompiled modules is when installing Linux on a clean system. This

typically requires setting up drivers so they can be used in the installation process for a particular Linux

distribution. Each Linux distribution has its own ideosyncracies, and it is not feasible for me to provide boot

and root disks for even just the common combinations of drivers and distributions.

PCMCIA is now a part of many of the major Linux distributions, including Red Hat, Caldera, Slackware,

Yggdrasil, Craftworks, and Nascent Technology.

1.9 Why is the package so darned big?

Well, first of all, it isn't actually that large. All the driver modules together take up about 500K of disk space.

The utility programs add up to about 70K, and the scripts in /etc/pcmcia are about 50K. The core driver

modules take up about 55K of system memory. The cardmgr daemon will generally be swapped out except

when cards are inserted or removed. The total package size is comparable to DOS/Windows Card Services

implementations.

Compared to DOS ``point enablers'', this may still seem like a lot of overhead, especially for people that don't

plan on using many of the features of PCMCIA, such as power management or hot swapping. Point enablers

can be tiny because they generally support only one or a small set of cards, and also generally support a

restricted set of host controllers. If someone were to write a genuinely ``generic'' modem enabler, it would

end up incorporating much of the functionality of Card Services, to handle cards from different vendors and

the full range of host controller variants.

2. Compilation and installation

2.1 Prerequisites and kernel setup

Before starting, you should think about whether you really need to compile the PCMCIA package yourself.

All common Linux distributions come with pre−compiled driver packages. Generally, you only need to

install the drivers from scratch if you need a new feature of the current drivers, or if you've updated and/or

reconfigured your kernel in a way that is incompatible with the drivers included with your Linux distribution.

While compiling the package is not technically difficult, it does require some general Linux familiarity.

The following things should be installed on your system before you begin:
