Thanks for that FF. Yesterday I tried a different software called DualServer which was on sourceforge. Its a DNS and DHCP server thats supposed to have all DHCP options. It would dole out the IP to the correct MAC complete with the right host name, but I was unable to get it to get the PXE from the tftp server. Unfortunately, the config file is just a txt .ini file with a zillion things in it and would require more time than I have today to comb through. I just went back to using it all in TFTPd32 temporarily until I have time to bang it out. I still dont know why I get all the ACK block stuff when downloading the files to the client. I'm going to try using different cable/port/NIC in the little server I have. Maybe that will make a difference. Maybe its something with my switch (Linksys SRW2048) which also has a zillion options to tweak.
On a side note. I'm noticing what look to be hangs, but are not reported as such in fahmon which just shows them sitting there not progressing. I have to kill the folding cores and reboot. I read in another thread that sometimes cores hang in linux but there is a work-around script. Is this something built into the notfred stuff? If so then that's not what my problem is, heh.
BTW, I'm not sure if I mentioned it, but thank you so much for everyone's efforts. A special "tip of the hat" goes notfred's way for having such a cool and almost no-brainer diskless setup available to anyone who wants to use it.
