The first row allows you to choose a Boot Method. Clicking on the menu on the right selects the Boot Method. The second row allows you to select the kernel for the Boot/Root set. You may either use the file selector button on the right hand side, or you may type in the location on the left hand side. The third row allows you to select the compressed filesystem you are providing, using either of the two ways mentioned before. You may use a pre-made root filesystem or you may create one using one of the Methods provided in the Advanced Root Section. The fourth row allows you to select the device you want to use. The default device is the first floppy disk (/dev/fd0). The fifth row allows you to choose the size of the device being used. The default size of 1440 assumes you are using a floppy drive (Note: You may want to experiment with 1722 which works fine with many floppy drives.), but can be used with other sized devices like tape drives. Click on the appropriate radio button to choose either gzip or bzip2 compression if the program doesn't automatically detect it. The slider bar on the right allows the output of the verbosity box to be changed from the highest (2) to the lowest setting (1) or to be turned off (0) or on again. At times it may be advantageous to turn off the verbosity box since large quantities of output to this box may cause gbootroot to use too much cpu power; however, output may still be found in the text file "verbose" in /tmp/gbootroot_tmp'time-date'. Advanced Boot Section: Libraries & Binaries & Modules check boxes: Turn off and on the stripping of symbols. The stripping behavior for libraries may be changed by clicking on the right mouse button to change --strip-debug to --strip-all. Binaries default to --strip-all and Modules default to --strip-debug. "Devel Device" If the device used for development is different than the actual boot device, use this field to indicate that device. You will have to run lilo -v -C brlilo.conf -r "device mount point" manually at a later time on the actual boot device. "Opt. Device" Add devices to the boot disk which are necessary for the kernel to function properly. Put a space between each device. For instance, /dev/fb0 for frame buffer devices. "append =" Add append options to brlilo.conf. If you are using a frame buffer device you could add something like video=matrox:vesa:402,depth:16. "Kernel Module" Add the modules found in /lib/modules/kernel-version which are necessary for the Boot Method to work properly. If these modules aren't found in the modules directory it is assumed that they either are in the kernel or they do not exist. In the case of 2 disk compression, floppy needs to be included in the kernel or included as a module. Kmod inserts the modules, and kmod needs to be built into the kernel along with initrd and ramdisk." "Kernel Version" Override the kernel version number found in the kernel header. This will change the /lib/modules/kernel-version directory. System.map: When a non-running kernel is chosen it is important to include a copy of that kernel's System.map file so that depmod can use the correct set of kernel symbols to resolve kernel references in each module. This can be found in the kernel's source code after compilation. Advanced Root Section: "Root Device" This is the device used for the root filesystem when constructing the Boot/Root set. You may choose a device which is different than the Boot device, but presently only floppy devices are supported. "Root Device Size" The size of the actual media used for the Root Device. "Root Filename" The name give to the root filesystem when initially made in the temporary creation location. The save button allows the creation to be saved in the permanent default location when the Accept button is pressed. "Filesystem Size" Root Methods make the filesystem the size which is specified here. "Compression" Off by default to allow user-mode-linux testing. Turn on compression when you are ready to use a Boot Method which requires compression. "Method" The root filesystem creation method. "Template" The template associated with a Root Method. Not all Root Methods have templates. "Generate" This puts the chosen Root Method in action. "UML" Abbreviation for user-mode-linux. This is a linux kernel which runs on top of the host system's linux kernel and allows a you run a live root filesystem. "Accept" This accepts the created root filesystem if it is found in the temporary creation directory. The UML box and the main section will now reflect the path to this root filesystem. You can now test with the UML button or put together a complete Boot/Root set with the Submit button. Advanced Kernel Section: Still in development. Little things you may want to know: * gBootRoot requires ash for initrd. Ash is a feather weight version of Bash.
