dnl $OpenBSD: prep,v 1.5 2015/08/02 09:54:29 jasper Exp $ By default MACHINE systems are shipped with a Linux (or proprietary) system installated on the CompactFlash card or USB drive. First connect your computer via serial port to the device (you may need to use a Cisco serial cable depending on your hardware) with a command such as "cu -l cuaU0 -s 115200" (assuming cuaU0 is your serial port device). Now apply power to the device and start it. Unless you have removed or changed the Linux installation it will be booted automatically. If you are quick you can interrupt booting (while still in U-Boot) with ^C. There are several ways to load an OpenBSD/MACHINE kernel (or ramdisk), over TFTP, from the internal CompactFlash or USB storage. Booting from a CF card or USB: To use the miniroot image you will need another machine to plug the SD card in to. Any machine type will do, as long as it supports SD card storage devices. Under OpenBSD, it will appear as a ``sd'' device, for example sd1. Use the dd(1) utility to copy the miniroot to the hard drive. The command would likely be, under OpenBSD: dd if=miniroot{:--:}OSrev.fs of=/dev/rsd1c Now load the ramdisk kernel using either of the following commands depending on the medium used. For USB: Octeon ubnt_e100# fatload usb 0 $loadaddr bsd.rd For Compact Flash use: # fatload ide 0:1 ${loadaddr} bsd.rd Booting over the network: For TFTP you will first need to setup a TFTP server as described in diskless(8). Assuming tftpd(8) chroots into /tftpboot, copy bsd.rd into that directory. Power on your OpenBSD/MACHINE device and from the U-Boot prompt set up networking. In this example it is assumed you have a DHCP server in your network: # dhcp If you don't have a DHCP server, you need to set the ipaddr U-Boot environment variable: # setenv ipaddr Now set the IP address of your TFTP server: # setenv serverip The ramdisk kernel needs to be loaded into memory. If you use "0" as the address, the default address location will be used by U-Boot: # tftpboot 0 bsd.rd Using octeth0 device TFTP from server 192.168.178.30; our IP address is 192.168.178.89 Filename 'bsd.rd'.
