Argon ISO

Hi,

I would like to create an ISO image of a DVD to run Argon on my PS2.

Background:
I have an unmodded "fat" PS2 with a hard drive and HDAdvance.
I was able to download the SMS ISO image to my PC and use the HDdump application (HDL_DUMB) to transfer the ISO to the PS2 HDD.
I was then able to run SMS application on my PS2

Wish:
I would like to create an ISO image with Argon but I am unsure about several of the parameters.

-Creation of the ISO image. I used the Roxio Creator Basic to create the DVD .ISO file.
Question 1: Can I just create a DVD ISO image with no special parameters? (i.e. the DISK does not need to be marked 'bootable')

-I modified the file: system.cnf to have:
BOOT2 = cdrom0:\xmb.ELF;1
VER = 1.00
VMODE = PAL/NTSC
to boot Argon.
Question 2: Is that correct?

-I left the line in the file xml.xml to still have:
<ule_path>mc0:/BOOT/BOOT.ELF</ule_path>

Question 3: What would happen if I changed it to:
<ule_path>cdrom0:\xml.elf</ule_path>

-When copying the ISO file to the PS2 using "HDL_DUMB" a startup file was expected. I entered "XMB.ELF" was that was the only .elf file in the image. Is that correct?

Thanks in advance,
Shane
