<P><FONT SIZE=2>Linuxbios.strip is 49152 bytes, and eepro100.elf is 22368. So that gives a total of 71520...larger than 65536. So one of them is too big. Any idea which?</FONT></P>

<P><FONT SIZE=2>Greetings,</FONT>
</P>
<P><FONT SIZE=2>It looks like the fallback image is being built wrong. </FONT>
</P>
<P><FONT SIZE=2>This can be hacked together manually. linuxbios.strip should be the</FONT>
<BR><FONT SIZE=2>actual</FONT>
<BR><FONT SIZE=2>LinuxBIOS code. The objective is to assemble a 64K (exactly) block</FONT>
<BR><FONT SIZE=2>containing:</FONT>
</P>
<P><FONT SIZE=2>1. etherboot</FONT>
<BR><FONT SIZE=2>2. null padding (can be generated with dd if=/dev/zero)</FONT>
<BR><FONT SIZE=2>3. linuxbios.strip.</FONT>
</P>
<P><FONT SIZE=2>I just use calctool to figure out how much padding to use and</FONT>
<BR><FONT SIZE=2>cat eepro100.elf pad linuxbios.strip >fallback.bin</FONT>
</P>
<P><FONT SIZE=2>the 64K fallback.bin can then be appended to the primary image to get</FONT>
<BR><FONT SIZE=2>the</FONT>
<BR><FONT SIZE=2>full rom image. </FONT>
</P>
<P><FONT SIZE=2>That's a little ugly, but it should get the job done.</FONT>
</P>
<P><FONT SIZE=2>Just as a final verification, in linuxbios.map, ZKERNEL_START for the</FONT>
<BR><FONT SIZE=2>fallback image should be 0xffff0000. That is whjere it will look for the</FONT>
<BR><FONT SIZE=2>fallback etherboot. Also, it will ljmp to ZKERNEL_START-8 to transfer</FONT>
<BR><FONT SIZE=2>control to the primary image. I'm slowly trying to disentangle that on</FONT>
<BR><FONT SIZE=2>the</FONT>
<BR><FONT SIZE=2>boards I have. Unfortunatly, I don't have a P4DPE.</FONT>
