HOWTO install OpenBSD on a Zaurus C3000

• First of all, prepare a Compact Flash card with a MSDOS partition and put zboot, zbsdmod.o, and bsd.rd on it. You will find those files on any OpenBSD FTP mirror in /pub/OpenBSD/snapshots/zaurus
• Remove power and the battery. Begin holding down the b and d keys. 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.
• mount /dev/hdc1 /mnt/cf   (CF device name can differ)
• mkdir /mnt1 && mount /dev/mtdblock2 /mnt1
• cp /mnt/cf/zboot /mnt/cf/zbsdmod.o /mnt1/root/etc/rc.d
• cd /mnt1/root/etc/rc.d
• Create a new file called rc.zboot
• Anker the rc.zboot file into /mnt1/root/etc/rc.d/rc.rofilesys so it gets executed at boot time, like that:

	71c71
	< /etc/rc.d/init.d/pcmcia start
	---
	> /etc/rc.d/init.d/pcmcia start; sh /root/etc/rc.d/rc.zboot
	170c170
	<	/etc/rc.d/init.d/pcmcia start
	---
	>	/etc/rc.d/init.d/pcmcia start; sh /root/etc/rc.d/rc.zboot
	239c239
	<	/etc/rc.d/init.d/pcmcia start
	---
	>	/etc/rc.d/init.d/pcmcia start; sh /root/etc/rc.d/rc.zboot

• insmod /mnt/root/etc/rc.d/zbsdmod.o
• cp /mnt/cf/bsd.rd /proc/zboot   (OpenBSD ramdisk kernel will boot now)
• Do the OpenBSD installation
• Reboot
