That would be great. If you succeed please post here how you did it.

you do know, that you need to have at least 1.2GB ram to run ubuntu properly if you want to do that?
since the image is going to be placed on the RAM (about 700MB) and then it will need 512MB ram to run...

so... it will load up slowly and ubuntu is not really a live linux distro

yes it will load slowly ~3MB/s, but boot image takes about 8(initrd.gz) + 2MB(vmlinuz) other files load directly to ram(not ramdisk) only if needet fron nfs, i thing.
now i have problems with nfs server, export list not work well & no smart tutorial is here in english...

nfs is working now for me

/opt/nfs/ 192.168.1.1/24(rw,insecure,sync,all_squash,anonuid=0,anongid=0)

the next step is in this tutorial, just follow it:

sorry guys i freeze on NFS over TCP is not running on the router, mean that nfs is ok but some rpc service is not installed :-(

Can any one help me?
I want to load knoppix.6.2.ru.iso (size 700MB) with PXE
Because my /opt partition size iz 512MB i have made directory in /tmp/mnt/[my_usb_drive]/knoppix and extract where 3 files from knoppix.6.2.ru.iso(linux, minirt.gz and KNOPPIX)
my /opt/tftpboot/pxelinux.cfg/default is

display boot.txt
prompt 1
timeout 0
default Knoppix

label Knoppix
  kernel /tmp/mnt/[my_usb_drive]/knoppix/linux
  append ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 initrd=/tmp/mnt/[my_usb_drive]/knoppix/minirt.gz nomce noapic quiet boot_image=/tmp/mnt/[my_usb_drive]/knoppix/knoppix

label DSL
  kernel /dsl/linux24
  append ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 initrd=/dsl/minirt24.gz nomce noapic quiet boot_image=/dsl/knoppix

but it doesn't work

couldn't find /tmp/mnt/[my_usb_drive]/knoppix/linux

DSL Linux is booting up, but says

Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.

why he says that?
what can i do to solve my problems?

you need to have all the data in the tftpboot dir...

creating a symlink in the tftpboot dir would probably solve the problem

ln -sf /opt/tftpboot/knoppix /tmp/mnt/[my_usb_drive]/knoppix

I dunno how you want to do it exactly, this is just an example
this will create a "shortcut" to your /tmp/mnt/[my_usb_drive]/knoppix directory.
Shortcuts are also like real files or folders, so you will see a new folder /opt/tftpboot/knoppix with the contents of the /tmp/mnt...

then you can redirect the tftpboot config to the /opt directory

Ok, tnx, i'll try

And what about DSL Linux? I can boot only kernel... why?

this solution doesn't work
also DSL under question
plz help

I thing 700MB is too much for PXE, the better way is using nfs or fetch squash filesystem from webserver.
