I am now dualbooting my OBSD / Cacko C3200 right now, using the standard Sharp --> OBSD --> Cacko procedure in
http://exit3.i-55.com/%7Exikon/bsdcacko.htmlHowever, (I have not tried it myself) I think by installing Cacko first, you can do the following steps to make your Z dual boot with OBSD:
1. In Cacko, use the
# insmod zbsdmod.o
# cp bsd.rd /proc/zboot
method to boot into the OBSD installer
2. Using the OBSD installer, re-partition your microdrive. DO NOT touch the first two linux partitions, reduce the size of the Win95 partition and make a new OBSD partition, as follows:
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
At this point you will not be able to boot into Cacko until you follow Step 2 and Step 3 of the dualbooting guide.
3. Continue installation of OBSD, follow the standard procedure but be sure use a CF card instead of a SD card. SD card reading under OBSD is still buggy and it took me some time to figure it out.
4. Make sure you can boot to OBSD by hitting enter when the boot selection prompt comes up.
5. Follow Step 2 and Step 3 of the dualbooting guide, you do not need to install Cacko again with Step 1. If boot to Cacko fails (very unlikely to be the case) you can always install Cacko again.
Please note also that your socket CF card will not be usable in OBSD. So you may have to buy an Ambicom / Asus or any other that are in the INSTALL.Zaurus list in OBSD ftp
