Dual boot setup

[Snooby]

Hi,

Nope, SD card is en route from US so takes a while

[Joshp]

I was just wondering how well versied are you in linux?  And on a side note do you have a sd card that is above 32mb?  By the way what brand of sd card did you order?

P.S. Just out of cursity where are you in the world?

[Snooby]

I know enough about linux to try things but not enough to fix them when they go wrong
I have a 32mb SD right now, SanDisk 256MB on order (somewhere over/on the atlantic)
I\'m in the UK

[Snooby]

It has arrived - gonna have a go at creating a dual-boot setup and then i\'ll let you know how i messed it up

[Joshp]

You cant mess it up to much.  Derekps daul boot setup is prerty seample once you under stand what it all does.  My 4 way dual boot setup is a little more complucated.  And also note that derekp did not relley need to mod open zaurus to much to do a dual boot, me on the other hand, I had to mod I little more to get the roms that where ment for internel flash to work right.

I should be back into the swing of things next week.  I\'ve been tied down with a heavy project load at work, and don\'t really feel like turning on a computer at home (so I\'ve been sorta neglecting this site for a while).
I\'ll see what I can put together this weekend (I promise :-).

Well, after a few tries I just couldn\'t get the darn thing to boot from my new SD card. I contacted SanDisk and they have agreed that the card is fu-*cough*, err broken

So....waiting for replacement :/

Did you try the other sd card driver form the ZUG download setcion.

It\'s broken - it gives errors when I try to format it on my PC

I\'m trying to accomplish this using my 5500, with a 64mb sd card and a 256mb cf card, hopefully dual-booting to oz. Since i am a total newbie, I can\'t really troubleshoot on my own, so thats where you guys come in.......... (hopefully)..........
When I type as root:
# /usr/local/bin/modrom-dualboot.sh
all the stuff comes up with \"This will rebuild your existing rom to support dual-boot home-on-sd AND support dual-boot root-on-sd......\" and everything looks to be going ok, it goes on about the nodes etc. until it gets to this point:

Writing superblocks and filesystem accounting information: done
copying current rom to temp image...
mkdir: Cannot create directory \'/tmp/tmp_src\': File exists
mkdir: Cannot create directory \'/tmp/tmp_dest\': File exists
Making modifications to new filesystem image.
Done making modifications
Building new initrd.bin
/usr/local/bin/mkcramfs: error while loading shared libraries: libz.so.1: cannot load shared object file: No such file or directory
Problem creating image

And thats it. But I cannot find tmp_dest or tmp_src in /tmp, and unless my file manager is lying through its teeth, libz.so.1 does exist.

Any help is much appreciated, as usual

You need to load Zlib for the compression.

[jem58]

Sorry, its me again. Thank you keithecampbell, now the scipt has sucessfully completed, so at least thats good. Now, this is probably just my naivety, but there is no zImage, so when I go to \"updateROM\" it says \"Image file is not found\". I have never flashed my ROM before, so I am new to this!   Do I need to download one of the zImages from www.openzaurus.org ?

Help is always appreciated

[jem58]

Well as there were no replies and im very impatient, I downloaded a zImage from the openzaurus website, and followed reflashing instructions, and now when I boot up my Z with or without storage cards inserted, an openzaurus banner is displayed on a black background and the only other feature is a thin white band at the bottom. There is a blinking indicator which probably should be typing the start-up text. In the worst scenario I perform a hard reset and restore my settings. Obviously this should not of happened, but if anyone could help me I could be grateful.

-------------------------------------------------
UPDATE: I\'ve just tried a hard reset and the same screen still displays! I really need some help now!!

-------------------------------------------------
UPDATED UPDATE  :wink: Well using my CF reader/writer I tried to delete the zImage and initrd.bin, but it still freezes at the same screen. SOMEBODY PLEASE HELP ME!!!!!!!

[jem58]

Phew........... I just consulted the unofficial zaurus faq, and I found my answer there; turns out there must have been a corrupt part (either the zImage or initrd.bin) and just by reflashing with the ospack my settings are back, which relieves me substantially.  
Just when I was losing hope..............

[jem58]

I\'ve just got the dual boot setup working, and I would like to express my gratitude to derekp and all the other people who have made this possible. You have no idea how much more useful this makes the Z! I was so relieved the first time openzaurus loaded up, and then when I removed my SD card the standard ROM appeared. Thank you all for doing something I dreamed of but didnt think possible on my 5500!
