Syslinux - May 2003 - tftp 3com 3c905c-tx PXE problem

Hi,

we want our PC's to boot from network;
therfore we use the following setup on a linux 2.4.19:

dchp: (ISC DHCPD 3.0.1rc9)
      ...
      option bootfile-name "boot.ovl";
      option tftp-server-name "saxophon.intern.ebewe.at";
      ...
tftp: (tftp-0.34)
      ...
      tftp          dgram   udp     wait    root      /usr/sbin/in.tftpd
in.tftpd -s /tftpboot -c

in directory /tftpboot:
      -rwxrwxrwx    1 root     root       109360 Feb 10 15:21 boot.ovl*

PC's:
      Networkscards with PXE (Intel, 3com)

with Intel NICs everything is OK; the PC gets the file boot.ovl and
executes it;

with 3com 3c905C-TX PXE I'll get an errormessage: "PXE-0E3B - File not
found"

now with a sniffer I see the following TFTP packet:
with Intel NIC:
      source file: boot.ovl
with the 3com NIC:
      source file: boot.ovl\200\004\254\020\375\001\377

and of course the file is not found!

Any suggestions?
Wolfgang
