[How to] PXE boot Server

[CrazyTSTer]

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?

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

not necessarily, you also need enough ram to load it up.
You need at least 700MB to save the image in RAM as well as the normal required RAM for running it

plus, loading 700MB takes some time with 3MB/s

The right knoppix settings is something like (knoppix 6.2):

label knoppix
  kernel knoppix/linux
  append ramdisk_size=100000 lang=en vt.default_utf8=0 apm=power-off vga=791 xmodule=fbdev initrd=knoppix/minirt.gz nomce quiet loglevel=0 tz=localtime
  append initrd=knoppix/KNOPPIX

btw. i update the guide, now include files for windows 7 PE booting, memtest x86 and readme.txt for some pxe distributions

The attached tftpboot.zip is broken?
Can't download it... says its invalid.

I have no problem with it, anyway...

Thanks!
Dunno what's happening/happened. This zip I can download. Just checked the file from 1st post again... works, though it crashes my browser
Well, I have it... now. Cheers.

You must edit
/opt/etc/xinetd.d/tftp
and set

user             = admin

instead of

user             = root

(you must use router's login. default is admin)
