I've found a way to support PXE booting both UEFI and BIOS architectures with Windows Server DHCP. This method uses a feature introduced in WinServer 2012: DHCP policies. First, in the the DHCP console, at the IPv4 root of the server, create a vendor class named PXEClient (UEFI x64) with the following value: PXEClient:Arch:00007 Then create your configuration for your BIOS clients in your scope or as global settings as usual by setting options 66 (IP or hostname of your TFTP host) and 67 (pxelinux.0). For the UEFI clients, you must then create a policy. In the con...

...e boot menu known from Intel PXE PDK so I need to run pxe service on redhat 8.0 with dhcpd 3 I run pxe and dhcpd on the same server. So the dhcpd server should give an extra parameter to pxe-clients. On Redhat 7.3 with dhcpd v2 this was done with the option: option dhcp-class-identifier "PXEClient"; On dhcpd v3 this option is rejected ! How do I get around this? many thanx Gerhard

Once upon a time, Steven Tardy <sjt5atra at gmail.com> said: > The ?ICMP unreachable? should be a dead giveaway. . . You cut out the part of the email where the OP said that the UEFI system was ignoring the next-server part of the DHCP reply and trying to TFTP to the DHCP server instead of the TFTP server. Of course that got ICMP unreachable, but it isn't a firewall problem. To the

Gene, I found a document from IBM that explains why it didn't like Vendor-Class-Identifier option I was using "PXEClient" was causing EFI boot rooms to dummy spit, that's very useful, that combined with RTFMing the PXE specs 3.0-3.2 might solve my problem if I keep at it. http://www-01.ibm.com/support/docview.wss?uid=swg21247032 Even the PXELinux docs suggest encapsulating vendor necessary options for some...

...above) eth0 - 1Gb ethernet (same public as above) These are both IBM systems. The firmware in the boot client is configured to PXE boot using eth4. DHCPDISCOVERY, OFFER, REQUEST and ACK appear as I expect with a pxelinux.0 file specified. Vendor class identifier is "PXEClient:Arch:00007:UNDI:003016" After a negotiation (option ack fails on first request cause of tsize, and I'm using tftpd-hpa 5.0), TFTP transfers the pxelinux.0 file (26 packets). Then the problem starts: 1) The whole DHCPDISCOVERY / OFFER / REQ / ACK / TFTP (pxelinux.0) se...

...y, There are at least 3 ways to set up your DHCP server to differentiate between std DHCP, BIOS PXE and UEFI PXE. Option 93 (arch) is one way. In ISC syntax, here's 3 ways: 1. Match on VCI class "pxe-clients" { match if substring (option vendor-class-identifier, 0, 9) = "PXEClient"; set vendor-string = substring ( option vendor-class-identifier, 0, 9); set vendor-class option vendor-class-identifier; option tftp-server-name "192.168.0.100"; next-server 192.168.0.100; if option vendor-class-identifier = "PXEClient:Arch:00000:UNDI:0...

A small how-to for encapsulating option 210 inside option 43 on Windows DHCP servers would be welcome then :-) And as far as UEFI x86 system go, one would simply have to create another vendor class with the value PXEClient:Arch:00006 On Wed, Jan 15, 2014 at 12:05 AM, Gene Cumm <gene.cumm at gmail.com> wrote: > On Tue, Jan 14, 2014 at 8:52 PM, Alexandre Blanchette > <blanalex at gmail.com> wrote: > > I've found a way to support PXE booting both UEFI and BIOS architectures > > with...

hi, i'm wondering aboot the option "vendor-class identifier" what means these two number? i have actually us it in my dhcpd.conf, and all is working, but i don't know what it mean.... if substring (option vendor-class-identifier, 0, 3) = "PXE" i have the same question for the "option vendor-encapsulated-options" ? this is just because, i just read a ltsp

...ftp was the nas, so I'll move it over to the linux box to get the traffic. The ideas I have now to fix is to try setting up atftp to do multicast tftp. "option bootfile-name" only freaks out the rom and adds extra characters at the end. If I have option vendor-class-identifier "PXEClient"; before Vendor-option-space PXE; Option PXE.mtftp-ip 0.0.0.0 It freaks out the rom and it says no offer found.

...on arch" conditions? _ Do you really need the Vendor Class Identifier option at all? It makes it play better with other devices that also use DHCP option 43, or something like that. Nope, I got desperate troubleshooting and searching the web for other solutions. Others were using just "PXEClient" which may have worked with legacy boot but not EFI. _ If you use Vendor Class Identifier, can you (or, are you allowed to) simultaneously choose a (boot)filename for each Client System Architecture Type? _ If you use Client System Architecture, can you (or, are you allowed to) simultaneo...
