USB booting :: booting dsl from SDMX1 512m mp3

I have a SanDisk SDMX1 512MB Flash mp3 player i would like to use to boot DSL.
I downloaded DSL 2.3 LiveCD and did a Pendrive install from the menu but after rebooting i wasnt able to boot from it on my GA-7VKMP motherboard.
If i copy the cd content to the USB and use Syslinux i get a "Kernel panic: VFS: Unable to mount root fs" error.
My question is what is the RIGHT way to do it? The most important thing is that i will be able to remove DSL from my mp3 player and it will be back at his initial state.
edit: where can i get the bootusb-x.x.x.img?

You can get the usbboot image from here.
You can find like everthing on it in here.
The way I did it was I downloaded the usb boot image and used winimage to write the image to my usb flash stick. Then I copied the KNOPPIX, boot, and Lost+Found folders from the disc to the usb's root and it works prefect for me. :blues:

thank you for your reply kendall14.
when i use winimage to write the bootfloppy-usb.img to the player i get a "SYSLINUX 2.04 (Debian 2003-06-06) Boot failed" message.
btw, i have Windows 2000 and Fedora Core 4 on the computer, so i can try some other methods aswell.
