Gene, As it happened I started working on this again just as you mailed me. It appears that PXE-E99 may also be related to MTFTP part of the PXE spec. IBM also says it has something to do with jumbo frames. I tried setting PXE.mtcp-ip to 0.0.0.0 to disable it but still no joy. The bootfile size shows up as zero because that relates to "option boot-size" in dhcp and doesn't seem to...

...act with a VCI stating that "arch = 7"; it doesn't make sense to me. Luke: It's trivial Arch 9 isn't used here yet, it's a typo it only ever sent out the Arch 7 one. I am using wireshark to confirm what the DHCP is sending out and receiving in both cases. The problem PXE-E99 is reported to be caused by MTFTP Failure (Dell our vendor & others) or Jumbo Frames on the Lan (IBM/Microsoft blogs). A different error usually reports incompatible DHCP options. Ady: Regarding the "ISC DHCP 3.1" syntax, you "think" it works? Luke: I test the configurati...

<snip > A: Because it messes up the order in which people normally read text, especially the archives of mailing lists. Q: Why is Top-posting such a bad thing? I apologize in advance for the potentially-dumb comments/questions. _ Do you really need the Vendor Class Identifier option included in the "if option arch" conditions? _ Do you really need the Vendor Class Identifier
