Unable to PXE Boot to Fog Menu.

@george1421 You are great! I did not pay as much attention to see this…

Thank you George,

Can you tell me which file to use? Secure boot is disabled. I setup based off of the Fog Wiki page which says to use the undionly.kpxe for all versions 0.33 to current. Under the DHCP Settings section on the wiki page.

https://wiki.fogproject.org/wiki/index.php/FOGUserGuide#Installing_FOG

Here is what my tftpboot file contains

10secdelay intel.kkpxe ipxe.kkpxe ipxe.usb menu.c32 realtek.kpxe undionly.kpxe
boot.txt intel.kpxe ipxe.kpxe ldlinux.c32 pxelinux.0.old realtek.pxe undionly.pxe
default.ipxe intel.pxe ipxe.krn libcom32.c32 pxelinux.cfg snp.efi vesamenu.c32
i386-efi ipxe.efi ipxe.lkrn libutil.c32 realtek.efi snponly.efi
intel.efi ipxe.iso ipxe.pxe memdisk realtek.kkpxe undionly.kkpxe

Thanks,

Joe

@Technolust Before I answer you, please answer this: What dhcp server are you using (manufacturer and version)?

Technolust

@george1421

Windows Server 2012 R2 Standard DHCP Version 6.3.

Hope that helps.

@Technolust Without sounding snarky, it will help you more than it will help me.

Follow this guide for configuring your dhcp server to dynamically support both bios and uefi systems that are pxe booting. https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
By following those instructions your dhcp server will hand out the right boot file name based the type of computer it is.

But to answer your original question the boot file for uefi 64 bit is ipxe.efi. The correct boot file for bios based systems is undionly.kpxe typically.

Technolust

Thank you George,

I created the policy and removed the options. However, is it possible to have two policies in place for x64 UEFI and x64 BIOS? This did allow me to access the Fog Server Menu from PXE boot.

@Technolust Umm, there is only one iPXE boot kernel for bios (undionly.kpxe) the kernel is 32 bits so it will run on both 32 and 64 bit systems. UEFI is the unique one where there is a kernel for 32 bits (/i386/ipxe.efi) and 64 bits (/ipxe.efi). Understand there are 2 64 bit type systems arch code 0007 and arch code 0009 that you need to create a rule for. Arch type 0006 is for 32 uefi and Arch 0 is for bios.

Just for reference:

           Type   Architecture Name
           ----   -----------------
             0    Intel x86PC
             1    NEC/PC98
             2    EFI Itanium
             3    DEC Alpha
             4    Arc x86
             5    Intel Lean Client
             6    EFI IA32
             7    EFI BC (EFI Byte Code)
             8    EFI Xscale
             9    EFI x86-64

Thanks George,

I think my question was vague. I created vendor classes for 00000, 00006, 00007, & 00009. I meant to ask should I apply the 00000, 00007? The only policy I created was the 00007 policy. I do not foresee us using any 32bit OS’s but I do see us using Legacy Bios. My guess would be to just apply all four of them but wasn’t sure if it made a difference.

george1421

@Technolust I would set the default dhcp options to undionly.kpxe to cover all bios machines, then create a filter for arch 0007 and 0009 that will cover all of the common uefi systems. We have seen some tablets that are 64 bit processors but pinned to 32 bits and report as 32 bits during pxe booting. If you don’t plan on any 32 bit processors then don’t add the filter. Just be aware of some of the tablets if you ever get one.

@george1421

Perfect!! Thank you George and Sebastian for your help and hopefully this helps others in the future.
