dnl $OpenBSD: install,v 1.28 2013/12/04 23:20:19 jmc Exp $ OpenBSDInstallPrelude OpenBSD is installed on the Zaurus by effectively converting Linux into a bootloader. This can be done easily by installing a package from Qtopia, or manually from a terminal. Both ways are described below, the easy one first. The package takes care of modifying the Linux startup files for you as necessary. To protect you from a common pitfall, ext3 filesystems mounted on /hdd[12] are converted back to ext2. (That way a fatal error in Linux startup scripts is avoided when the journal has been destroyed by mounting one of the ext3 filesystems as ext2 on OpenBSD). 1. Press "Home" until the second icon tab is selected (Settings). 2. Open the "Add/Remove Software" dialog. That's the green icon with an arrow pointing from left to right into a rectangle. 3. Press "Install packages via networks", the middle one of the three big buttons. The "Package Manager" dialog pops up. 4. Press the yellow switch icon in the lower right corner to bring up the "Package Servers" dialog. 5. Press the left button, which is labeled "New" if your Zaurus is in English, enter the HTTP/FTP URL of the nearest OpenBSD mirror, and change the field above the URL into a name for that server. Press the "OK" button in the upper right corner to return to the "Package Manager" dialog. 6. Press the "Upgrade" button in the lower left corner to update the package index if that was not done automatically. A package named "openbsd" should appear in the package list. Select this package and press the question mark icon in the lower right corner. 7. Now you see the package details and three buttons, labeled "Install", "Remove", and "Ignore" in this order. Press the leftmost button and twice "OK" to finish the installation. Then close the "Add/Remove Software" dialog. 8. Activate the "Q" menu in the lower left corner of the screen and choose "Reboot" (that's the item with a green icon next to it, above the power-off icon). Wait for the system to reboot. At the boot> prompt, hit enter to boot OpenBSD, or type 'r' to boot Linux. Since you want to install OpenBSD, this time you will want to type 'r'. 9. Wait while Linux is coming up, then switch to the first tab (Applications), scroll down, and press the icon which is labeled "Install OpenBSD". A few seconds later, an OpenBSD bsd.rd will boot on your Zaurus, so that you can perform the standard install process. Another way to install the package is from a shell. You will need the following file from the distribution on the Zaurus: openbsd{:--:}OSrev{:--:}_arm.ipk Perform the following operation as root to install the package, and then continue as in step 8, above: {:-#-:} ipkg install openbsd{:--:}OSrev{:--:}_arm.ipk To install the OpenBSD boot program manually, you will need the following files from the distribution: zbsdmod.o zboot bsd.rd After starting up some sort of terminal emulator on the Zaurus and becoming root, perform the following operation: # insmod zbsdmod.o # cp bsd.rd /proc/zboot A few seconds later, OpenBSD will boot on your Zaurus. If you already have a bsd.rd or bsd kernel contained in a FFS partition on the C3x00 hard drive, you can instead use # insmod zbsdmod.o # ./zboot OpenBSDInstallPart2 OpenBSDInstallPart3(,"wd0") OpenBSDInstallPart4 OpenBSDInstallMBRPart1 One of the three partitions on the Zaurus C3x00 hard drive is a 3GB or 5GB MS-DOS filesystem. This partition has application and user data on it and can be a lot smaller. It is therefore recommended that you cut most of the space off this large MS-DOS partition, and create a new A6 partition afterwards, like this: 0: 83 0 3 13 - 1511 7 17 [ 63: 205569 ] Linux files* 1: 83 1512 0 1 - 7559 7 17 [ 205632: 822528 ] Linux files* 2: 0C 7560 0 1 - 9065 7 1 [ 1028160: 204800 ] Win95 FAT32L 3: A6 9065 7 2 - 67885 5 3 [ 1232960: 7999488 ] OpenBSD After shrinking the MS-DOS partition, you will need to reformat it from Linux or OpenBSD once OpenBSD is installed. (You will be reminded of this later in this document) OpenBSDInstallMBRPart2 OpenBSDInstallPart5({:- If you have Linux partitions defined on the disk, these will usually show up as partition 'i', 'j' and so on.-:}) OpenBSDInstallPart6({:-CD-ROM, -:}) OpenBSDURLInstall OpenBSDCDROMInstall OpenBSDDISKInstall({:-"wdN" or -:},,{:-, Linux (ext2) or MS-DOS-:}) OpenBSDCommonInstall OpenBSDInstallWrapup OpenBSDCongratulations If you have kept the MS-DOS partition, do not forget to newfs it using: newfs -t msdos /dev/rwd0k This should be done before attempting to mount and use this partition from Linux or OpenBSD. For purposes of recovery in case Linux becomes inoperable for one reason or another with HDD1 Errors and such, we detail the process to come up single user: Remove power and the battery. Begin holding down the 'b' and 'd' keys. Wait for 1 minute. Insert battery and power on unit. As soon as a login screen starts to show up, release the 'b' and 'd' keys. Login as root. The following sequence is also recommended inside Linux so that problems will happen less often. By default the boot scripts fail if the MS-DOS partition is corrupt in any way. If you are already root do the following, which will skip mounting the MS-DOS partition. Login as root. Find the rc.rofilesys file. It is either in /root/etc/rc.d cd /root/home/etc/rc.d Or you have to mount it using: mount /dev/mtdblock2 /mnt cd /mnt/home/etc/rc.d cat rc.rofilesys | sed -e '/vfat/s/^/#/' > vfat diff -u rc.rofilesys vfat # to double check cp rc.rofilesys rc.rofilesys.vfat cp vfat rc.rofilesys In these cases below we avoid using vi because Linux quality is of such high caliber that vi locks up the console. If you logged in multiuser you may be able to use vi. Please be aware that if you fsck the two Linux partitions on the disk, they are actually ext3fs partitions and you will thereby corrupt their journals. This will make them into ext2fs partitions. Linux will not be able to boot, and you will need to use the processes below to get to the point where Linux will mount them as ext2fs partitions: Login as root. Find the rc.rofilesys file. It is either in /root/etc/rc.d cd /root/home/etc/rc.d Or you have to mount it using: mount /dev/mtdblock2 /mnt cd /mnt/home/etc/rc.d cat rc.rofilesys | sed -e '/^LINUXFMT=ext3$/s/^/#/' \ -e '/^#LINUXFMT=ext2$/s/^#//' > ext2 diff -u rc.rofilesys ext2 # to double check cp rc.rofilesys rc.rofilesys.ext3 cp ext2 rc.rofilesys OpenBSDUnattendedInstallation
