This section outlines the steps to do so. - -The overall idea is to have a filesystem with some tools (sysinst, ls, -whatever), and embed this filesystem as some sort of ramdisk into a NetBSD -kernel. The kernel needs to include the `md` pseudo device to be able to hold a -ramdisk. The kernel with the ramdisk can then be put on removable media or made -available via the net (using NFS or TFTP). - -To perform the following steps, you need to be running a kernel with the `vnd` -pseudo device enabled (this is the default for a GENERIC kernel). - - 1. First, you must create a valid kernel to put on your floppies, e.g. - INSTALL. This kernel must include the `md` pseudo device, which allows - embedding a ramdisk. See [[Compiling the kernel|guide/kernel]] for kernel - building instructions. - - 2. The next step is to create the ramdisk that gets embedded into the kernel. - The ramdisk contains a filesystem with whatever tools are needed, usually - [[!template id=man name="init" section="8"]] and - some tools like sysinst, - [[!template id=man name="ls" section="1"]], etc. - To create the standard ramdisk, run `make` in the - `src/distrib/i386/ramdisks/ramdisk-big` directory (for NetBSD 3.x: - `src/distrib/i386/floppies/ramdisk-big`). - - This will create the `ramdisk.fs` file in the directory. If you want to - customize the contents of the filesystem, customize the `list` file. - - 3. Now, the ramdisk gets inserted into the kernel, producing a new kernel which - includes the ramdisk, all in one file. To do so, change into the - `src/distrib/i386/instkernel` directory (for NetBSD 3.x: - `src/distrib/i386/floppies/instkernel`) and run `make`. - - 4. The next step is to make one or more floppy images, depending on the size of - the kernel (including the ramdisk). This is done by changing into - `/usr/src/distrib/i386/floppies/bootfloppy-big`, and running `make` again. - - This will create one or two (depending on the size of kernel) files named - `boot1.fs` and `boot2.fs` - - 5. Last, transfer these files to the floppies with the commands - - # dd if=boot1.fs of=/dev/fd0a bs=36b - # dd if=boot2.fs of=/dev/fd0a bs=36b - - 6. Put the first floppy in the drive and power on! - -## Creating a custom install or boot CD with build.sh - -Creating custom install or boot CDs is easy with `build.sh`. The NetBSD base -system includes the -[[!template id=man name="makefs" section="8"]] -tool for creating filesystems. This tool is used to create iso-images. Creating -iso-images includes these tasks: - - 1. Release build - - #./build.sh release - - 2. CD-ROM iso-image build - - #./build.sh iso-image - -The `build.sh` iso-image command will build a CD-ROM image in -`RELEASEDIR/MACHINE/installation` - -**Warning**: For now not all architectures are supported.
