1dnl $OpenBSD: prep,v 1.5 2009/02/01 15:36:16 simon Exp $ 2 3The MACHINE computers do not generally need any specific preparation. 4 5You might want to check that the console ``path'' in the PDC firmware 6points to the device you plan to use, and change it if necessary. Most 7MACHINE machines will allow to select console path from the BOOT_ADMIN> 8prompt. To reach this prompt, abort the autoboot process and if a menu 9appears, enter ``a'' to select the "Boot Administration mode." 10 11To select the first serial port as console, type: 12 13 BOOT_ADMIN> path console rs232_a.9600.8.none 14 15or to select graphics as console: 16 17 BOOT_ADMIN> path console graphics 18 BOOT_ADMIN> path keyboard hil 19or 20 BOOT_ADMIN> path console graphics 21 BOOT_ADMIN> path keyboard ps2 22 23depending upon your keyboard type. 24 25On a few models, such as the 9000/712, the PDC firmware will not allow 26the console path to be changed. In this case, it is possible to change 27it from the OpenBSD boot loader. After booting OpenBSD in interactive 28mode (for example, if booting over the network, by entering ``boot lan 29isl''), enter the following at the ``boot>'' prompt: 30 31 boot> machine console rs232.9600.8.none 32 33dnl I hope I'll never write ``been there, done that'' here. Rest 34dnl assured I have added a lot of safeguards in this console code 35dnl to prevent people from rendering their 712s unusable. 36dnl At least mine is still alive, and I have played a lot with its 37dnl console path... -- miod 38WARNING! 39 Make sure to type the console path correctly or the 9000/712 can 40 become unusable, and will require a special ``dagger'' board to 41 be revived. 42 43After changing the console path, the machine has to be power cycled 44for the changes to take effect. 45 46In most cases the primary boot device path is already set to the right 47value. If not, it is advised to run: 48 49 BOOT_ADMIN> search 50 51to display the list of all bootable devices before choosing one with: 52 53 BOOT_ADMIN> path primary SCSI.TARGET.LUN 54 55Substitute FWSCSI or SESCSI for SCSI if it is displayed as such in the 56path list obtained from ``search'', and use the TARGET and LUN values 57matching the device intended as the boot device. 58 59To set up autoboot, use the configure option: 60 61 BOOT_ADMIN> co auto boot on 62 63or if your machine has the old style PDC interface: 64 65 BOOT_ADMIN> autoselect on 66 67Please refer to the boot(8) manual page for more information on PDC 68settings and boot commands. 69
