I built a PXE server system as described at http://www.funtoo.or...ork_boot_server

 

There were a few things I needed to do differently to get things to work even partially.  For example, I needed to add these additional files to my /tftproot:

ldlinux.c32
libcom32.c32
libutil.c32

There is another quirk in that the initial menu displayed on the system that is trying to boot via PXE is allowing a 1,000sec timeout versus the 10sec I was expecting via the pxelinux.cfg/default file.

 

The issue I am having now is that I get all the way through the loading of the initrd=srcd/isolinux/initram.igz loading, but then the system trying to boot can never find the  netboot=http://172.16.3.213/sysrcd.datfile.  What happens instead is that the system booting completes the network configuration via the initrd but then reports

Searching for device with /sysrcd.dat

It fails to find it, then tries to mount all the SATA partitions (3 disks with a total of 22 partitions among them), then reports again

!! Cannot find a device with /sysrcd.dat. Retrying...

It does this several times, then gives up dumping me to a "mini shell".

 

I searched the at-large internet, and can't really find anything that helps.

 

I have tried offering the sysrcd.dat and the sysrcd.md5 files via apache and vsftp.

 

Here is the output from tcpdump:

And here's what happens when I wget the files directly:
