=== 2 TODO plan
* Complete reading UDF plain disks
* Complete and test reading Blu-ray disks
* Complete support big-endian arch`s
* Implement initial writing support for UDF plain disks

=== 3 How to test ===
==== 3.1 Download sources from my branch ====
>bzr branch lp:~medvedeva-julia/helenos/udf helenos

==== 3.2 Compile sources ====
>cd helenos

>make PROFILE=ia32


==== 3.3 Create udf disk image under Linux ====
To create udf image under Linux you need to install package with udf utilities. For example at Arch its udftools. The package should contains mkudffs tool.

>mkudffs --media-type=hd --blocksize=512 --utf8 ./udf.img

You can also select media type: "hd" or "dvd" and blocksize: 512 or 2048 or something else.


==== 3.4 Mount udf disk image under Linux ====
You can mount udf image (from step 3.3) under your Linux host and copy several files in it.
>mount -o loop -t udf ./udf.img /mnt/udf-mount-point

>where udf.img - image from step 3.3


==== 3.5 Boot HelenOS with user disk image ====
To boot HelenOS run qemu:

>qemu-system-i386 -m 512 -boot d -hda udf.img -cdrom image.iso

udf.img    - udf disk image


==== 3.6 Mount user disk image under HelenOS ====
In HelenOS run batch script to run udf server, ata server and mounting first ata disk as udf

>batch u

Then, go to /mnt directory:

>cd /mnt

and here you are :)
