Seriously less than 512. If that is the case then maybe that is why my Dell D820 will not read the knoppix image file. I seriously dought its a bios or USB issue on my end especially if it can boot the kernel and create the ram disk with initrd.

It has to be that I set my size over 512 have to check that out.

Ext3 or ext2 should I create for the linux second partition?

Or it could be a timing issue. If I could somehow put some kinda command on the kernel script line or APPEND another line with some kinda script to slow the USB down a bit I bet it will read the USB media and boot the Knoppix image.

I think its a DSL script issue and not my laptop because I can boot any program using Ultimate Boot USB and I mean any except DSL.

So I am convinced its a DSL scripting issue

Is the file ldlinux.sys present on your USB stick? Roberts mentioned elsewhere:

The lack of the ldlinux.sys is caused by the failure of the syslinux command, typically

syslinux /dev/sda1

This seems to happen more frequently on larger drives.
A work-around seems to be...

Create a .mtoolsrc file which contains mtools_skip_check=1
e.g.,

echo "mtools_skip_check=1" > .mtoolsrc

Then running the usbhdd script seems to correct the problem.
I will add the .mtoolsrc file to the next release.

If you use ext2, there is no particular need for more than one partition unless you want to go this way. I never tried ext3...

I remember reading that about mtools. I have been just following Wiki's how to Install on USB flash. Used Method II install from a linux Environment.

Did not go any further than that. Now you really have me interested in trying that.

Keep in mine I did not do it the syslinux way. I am using a Boot loader Grub but if there is another way to get it to real the Knoppix file I'll do it. You have a link for the step by step? Maybe an addendum to Wiki Don's eventually?

Here is the link I am following> If you can get me a better linke to get thing to work go right ahead. Kepp in mind though this USB stick with the two partitions one Vfat 32 first partition and the second Ext3 linux works on all PC I have tried so far except my D820.

For me, the simplest way to install to USB stick (rather than USB hd) is to boot from a DSL cd and then use the right-click menu to navigate to create USB-HDD boot.

In order to try Roberts work-around, you would need to create the /home/dsl/.mtoolsrc file before you start.

One more thing add that file before I start but add that file while in DSL from the CD? I had a hard time mounting USB stick when booted off CD?

Can I create the file before I boot off the CD? But then when I create the DSL it will probably format the stick and re-write the file I created right?
