Uggh. Some are not supported by most although some are supported by
flavor x. That could ba candidate entry in the Most Obfuscated Tech
Manual contest.
Probably just needs to be 2 sentences, how about
These network cards are unsupported by the stock Debian kernels:
a,b,c.
These network cards are supported only by the udma-100-ext3 flavor: d,e,f.
You can create a custom kernel which supports an otherwise unsupported
card and then substitute in the installer (ref id="rescue-replace-kernel").

<p>
If you have no AT-style keyboard and only a USB model, you will need to enable
legacy AT keyboard emulation in your BIOS setup. Consult your mainboard manual
and look in the BIOS for "Legacy keyboard emulation" or "USB keyboard support"
options. It must be enabled in order to boot the installation system.
If you enabled this option and it is working for you, you
are fine and can go ahead.
<p>
If you cannot find this option, it might be that it is always enabled
and you can continue. It also might mean that the BIOS does not
provide any emulation support (bad luck here).
<p>
If you find the option and enable it, but the emulation stops working
soon after the kernel started, then you have bad luck too.
<p>
Sometimes, the emulation hangs but it wakes up after few minutes, so you could
wait some time and try to continue. If it does not restart, you may try to
install Debian from a CDROM which contains the "udma100-ext3" boot flavor. This
kernel has a basic USB driver built-in and should load it at the right time.
<p>
Using floppy disks rather than a CDROM may lead to another problem. The USB
keyboard driver subsystem on some machines doesn't start up quickly enough
during the boot process to be available when the prompt is given to insert the
root disk. If you have a USB keyboard and get no response at the root disk
prompt, try attaching a regular (AT) keyboard in order to enter <Return>. Then
the AT keyboard can be detached.
