In general, if you're compiling a kernel for yourself, you know what hardware it will be running on and you know what features you want it to support. If you want the kernel to be able to do something, compile that feature into the kernel. If you don't need a particular feature, don't waste time compiling the module.
However, sometimes modules have their uses. In particular, if the speedtouch driver is built into the kernel it may request the firmware from udev before the root filesystem has been mounted. To avoid this, compile the speedtouch driver as a module. If the module can be loaded the firmware should be available too.
The problem is a race condition, and it depends on your hardware. If it works for you with the speedtouch driver built into the kernel then go with that. But if you have problems loading the firmware, try recompiling the kernel with the speedtouch driver as a module and load the module from the bootscript.
You need to know what sort of USB controller you have. Find out with lspci (part of pciutils - PCI Utilities in BLFS)
Enable support for either UHCI or OHCI, not both.
You'll need to know if your ISP uses PPPoA or PPPoE. When you get to configuring PPP you'll need to know the VPI/VCI numbers for your country/ISP. Those details can be found on this table
cd into the kernel source, make menuconfig and enable these options
When you've finished, save the .config file then execute make. When it's done copy arch/i386/boot/bzImage to /boot. If you compiled some modules you'll need to run make modules_install and copy the file System.map into the same folder as your kernel. Edit Grub's menu.lst to point to your new kernel.
Download a copy of linux-atm-2.4.1. You will need to patch it to compile it with recent (gcc-3.4 or later) versions of gcc. linux-atm-2.4.1-gcc-4.patch
Untar linux-atm, cd into it, patch it, configure and make it
Enter roots password then
You need to install pppd after libatm so that ppp builds the pppoatm.so plugin. Download a copy of PPP-2.4.4, untar ppp, cd into it, configure and make it
Enter roots password then
If you have a copy of the firmware that you know works with your modem, stick with that. Most people will use the firmware in the SpeedTouch330_firmware_3012.zip.
If you're not sure what revision of modem you have, first, as root, mount usbfs on /proc/bus/usb
Now you should be able to find out what revision your modem is with this command
Since 2.6.10 the kernel has been able to load the firmware itself, but it need to be split into two parts first with the firmware-extractor. Untar the firmware-extractor.tar.gz and put a copy of your firmware in the firmware-extractor folder. Rename the firmware mgmt.o, then it's the usual configure, make, make install
That will split the firmware into speedtch-1.bin and speedtch-2.bin. To copy it into hotplugs firmware folder, enter roots password then
That will copy speedtch-1.bin and speedtch-2.bin to /lib/firmware
Become root and create the folder /etc/ppp/peers
Now create a plain text file called either /etc/ppp/chap-secrets or /etc/ppp/pap-secrets with a text editor. If you don't know if your ISP uses chap or pap authentication put your a line like this in both files, it won't do any harm.
username@isp should be the username your ISP knows you by. Usually (but not always) it has an @isp bit at the end (it might be @dsl.fs, for example). Change password for the password you chose when you set up your internet account. Don't miss out the spaces in the " "*" " bit.
If your ISP uses PPPoE skip down to the PPPoE section
Copy and paste this into a text editor then save it as /etc/ppp/peers/speedtch
Change username@isp for the username your ISP knows you by and change the 0.00 for the VP/VC values for your country/ISP. In Britain it's 0.38, for example
When you reboot the kernel will detect the hardware and get hotplug (or udev) to load the firmware. All that's left to do is to get pppd to call your ISP. This can be done with the command `pppd call speedtch'.
This bootscript will wait till the firmware has loaded then call pppd. As root open a text editor then copy, paste and save it as /etc/rc.d/init.d/dial
Now, make it executable, make a symbolic link pointing at it from /etc/rc.d/rc5.d (so it gets run on boot), change the permissions on the scripts you've put in /etc/ppp so that they're not world readable and make a symbolic link from /etc/resolv.conf pointing at /etc/ppp/resolv.conf. Open a root shell and copy this into it
When you reboot into init 5 it should connect you to the web.
Please report any problems to the mailing list
For PPPoE over ATM things are a slightly different. You'll need a copy of the br2684ctl bridging utility. Compile it with the command
Enter roots password and copy it to /usr/sbin
Copy and paste this into a text editor then save it as /etc/ppp/peers/speedtch
Change username@isp for the username your ISP knows you by. Often (but not always) it has an @isp bit at the end.
When you reboot the kernel will detect the hardware and get hotplug to load the firmware. You'll need to use the br2684ctl to create a bridging connection, configure it with iproute then get pppd to call your ISP. This can be done with a bootscript. As root open a text editor then copy and paste this and save it as /etc/rc.d/init.d/dial
Change VP.VC for the VPI/VCI numbers for your country/ISP. For example in Portugal it's 0.35
Now, make it executable, make a symbolic link pointing at it from /etc/rc.d/rc5.d so it gets run on boot, change the permissions on the scripts you've installed in /etc/ppp so that they're not world readable and make a symbolic link from /etc/resolv.conf pointing at /etc/ppp/resolv.conf. Open a root shell and copy this into it
When you reboot into init 5 it should connect you to the web.
