[syslinux] PXE2.2 does not work, PXE2.0 does

[Databyte]

Thank you for your response.

The older 3Com nics that do work are using the 4.00 MBA version. This MBA is
using PXE2.
The newer 3com nics are using MBA 4.30. During boot, they show PXE version
2.2
The other visual difference we can see is that the newer 3com's display a
GUID number (of all zeros). The older 3com's dont show a GUID number. Maybe
this has something to do with it.

With the 4.30, the client shows:

PXELinux 2.00 2002-10-25
UNDI data segment at:	0009d660
UNDI data segment size: 3838
UNDI code segment at:	00090000
UNDI code segment size:	25A0
PXE entry point (we hope) at 9D66:00F6
My IP address seems to be 0AB00166 10.176.1.102
IP=10.176.1.102:0.0.0.0:10.176.1.254:255.255.255.0
TFTP prefix: /tftpboot/
Trying to load: pxelinux.cfg/0AB00166
Trying to load: pxelinux.cfg/0AB0016

and so on....
The time between the tryings is about 30 seconds.
The only configuration we have is default

On the TFTP server we see the following:
Connection received from 10.176.1.102 on port 2070
Read request for file </tftpboot/pxelinux.0>. mode octect
OACK: <tsize=10820>
Peer returns ERROR <tftp aborted> -> aborting transfer
Connection received from 10.176.1.102 on port 2070
Read request for file </tftpboot/pxelinux.0>. mode octect
OACK: <blksize=1456>
<tftboot/pxelinux.0>: sent 8 blks, 10820 bytes in 0s. 0 blks resent

We are using NT4 DHCP and Tftpd32 by Ph Jourin version 2.21


Hope someone can help us out.
Thanx!

Please specify which version of the 3Com MBA you're using, ("PXE 2.0" 
and "PXE 2.2" aren't valid MBA versions) and what the exact failure mode is.

For what it's worth, the 3Com MBA has been one of the most problematic 
PXE implementations.
