[syslinux] Error PXE-T01: File not found

[Kosolapov Dmitry]

Hi, everybody!
Problem in "tftp:(ack) Connection refused" was resolved with physically
turning on client PC to the server's subnet (4th).
Now I try to do remote booting, but after DHCP-request (it's
successfull) I get the error "PXE-T01: File not found, PXE-E3B: TFTP
Error - File Not found, PXE-M0F: Exiting Broadcom PXE ROM.
I followed
http://docs.sun.com/source/817-5625-10/Linux_Troubleshooting.html
instructions but everything suits to its requirements at my end.

At server: tail -f /var/log/messages:
Apr  1 23:33:03 dk in.tftpd[2997]: RRQ from 192.168.4.251 filename
/tftpboot/pxelinux.0
The structure of my tftpboot:
  16 -rwxrwxrwx  1 root root   12976 Mar 23 13:07 pxelinux.0
   4 drwxrwxrwx  2 root root    4096 Mar 26 00:07 pxelinux.cfg
8616 -rwxrwxrwx  1 root root 8804531 Mar 28 02:37 vmlinuz-2.6.16


Please provide me the reason of such a strange behavior. Thanks forward.
