Smile problem on create a PXE diskless OS, initrd not found...

Hi, I want to setup a PXE boot diskless OS, I have donwload a Thinstation-2.3beta2.tar.gz, inside this program have folder boot-images,kernel, packages,src...and many files, so i already configure my server DHCP & bootp ok, TFTP ok, the problem is i dont know this Thinstation-2.3beta2 how to place a files and folder inside my server /tftpboot folder, i success boot from client, but i said cannot found initrd, so i check on Thinstation-2.3beta2 files, than i copy all related initrd files to server /tftpboot folder, but still same? Any body know if want to use Thinstation-2.3beta2 as a PXE diskless OS, than how to copy a needed files and folder to /tftpboot folder on my server.

I also have try to use puppy linux to do as my PXE diskless OS, i success boot to this OS from my PXE client, but it said cannot found a file pup_400.sfs, but i already put this file inside my server /tftpboot folder.

This puppy linux ISOLINUX.CFG look like this:

default puppy
display boot.msg
prompt 1
label puppy
kernel vmlinuz
append initrd=initrd.gz pmedia=cd
timeout 50

so i rename it to default and copy to my server /tftpboot/pxelinux.cfg folder.

I have try to deleted file ISOLINUX.CFG line 6 pmedia=cd , but still cannot success boot into full system, it said cannot found PUP_400.SFS file.

Thank u.

Have you tried looking at the TFTP server from another computer to see what is actually being made available? Perhaps there is some permission issue that is keeping the initrds from being visible. You might also want to check the error logs as it should note the reason a download was denied.

What does the appropriate pxelinux.cfg entry for the client look like? In your /tftpboot directory there should be a directory called pxelinux.cfg. You'll need to find the file in here that the client uses to boot from (their based on IP address generally -- see the pxelinux documentation for more details -- if there's just a file called default then that's the one you want). You need to make sure that the initrd specified in the config file is available to the client.
