1dnl $OpenBSD: prep,v 1.6 2020/05/17 17:04:28 deraadt Exp $ 2The default configuration of the MACHINE systems comes with a Linux 3installation on the disk (either an IDE hard drive, or a CompactFlash 4card). At the moment, there is no known way to log in this installation 5as ``root'' or interrupt the boot process, and start an OpenBSD 6installation procedure. 7 8Because of this, the only way to boot the OpenBSD install is to copy 9the miniroot "miniroot{:--:}OSrev.img" image to the hard drive or CompactFlash 10(on the other hand, upgrades can be started by copying bsd.rd to the 11 OpenBSD disk and booting from it). 12 13As a result, you will need another machine to plug the machine's disk 14or CompactFlash in. Any machine type will do, as long as it supports 15ATA-compatible storage devices, regardless of the partition scheme 16it uses. Under OpenBSD, it will appear as a ``wd'' device, for example 17``wd1''. 18 19Use the dd(1) utility to copy the miniroot to the hard drive. 20The command would likely be, under OpenBSD: 21 dd if=miniroot{:--:}OSrev.img of=/dev/rwd1c 22Replace ``rwd1c'' with the appropriate device name for the raw device 23on the system used to do the copy. 24 25If the machine has a hard drive, and you had to change jumpers on it 26to change its ``master'' status, do not forget to configure it back 27to ``master'' or ``single drive'', as slave drives are not bootable. 28 29dnl I need to write a comprehensive text, also explaining that Rx/Tx 30dnl are swapped between the CF and HD models. 31In addition to the disk preparation, you will need to connect a serial 32port connector to the machine.
