Thanks; that explains the root cause of the problem.<br>
<br>
The BIOS is allocating a PMM block at 0x106d80 to hold a
copy of the raw <br>
ROM image, but failing the second PMM allocation for the
temporary <br>
decompression area.<br>
<br>
The default temporary decompression area used by iPXE if PMM
allocation <br>
fails is at 0x100000 (i.e. the start of high memory). The
decompressed <br>
ROM image is therefore overwriting the copy of the raw ROM
image, which <br>
leads to the CRC32 checksum failure.<br>
<br>
What banner line did you get on this system with the
(working) DFE-530TX?<br>

<div>I did another type of test now:</div>
<div><br>
</div>
<div>I disabled AUTOBOOT_ROM_FILTER in config/general.h and
recompiled the 905b rom file.</div>
<div>I then flashed it to the 29C512 chip but this time I
installed this chip into the DFE-530TX D-Link card. I put
both cards into the same machine with the 3com card installed
without a bootrom chip. When I started the machine, the 3com
code in the d-link card executed successfully this time and
found the 3Com pci card and did a successful dhcp connection.
Interestingly both roms report 00000000 on the second address
of there banner pages.</div>

<p>I wouldn't be surprised if we are dealing with flacky BIOS.</p>
<p>Testing the NIC in a totaly different computer could confirm that
gut feeling.</p>
