How to configure BIOS to PXE boot using only IPV4?

[David_V_Intel]

Hello DZhan20, Thank you for posting on the Intel ® communities. I will need more information of the situation, in this case, I can see that you have not provided me with the model of the Intel ® NUC. Also, I would like to know if you want to PXE boot strictly with IPv4. Let me know please. Regards, David V Intel Customer Support Technician Under Contract to Intel Corporation

Hi David,      Thank you for your reply. I have NUC5i5RYK and NUC5i3RYK. I updated the BIOS recently. The PXE boot try IPV6 first, and then IPV4, each takes a long time. To strictly use IPV4 at least saves half of the time. Also IPV6 is not being used in my environment.      I configured to boot disk, ipv4 and ipv6, and in that order from top down for UEFI. It doesn't seem I can take ipv6 away from the list. The PXE boot and the OS installation turned out successful. Dalton

Hello DZhan20, Thank you for your response. I am glad to know that the OS installation was successful, IPv6 has a higher priority and always stays in the boot order before IPv4; however, as a workaround, you can uncheck/disable “Boot network Devices Last” in the BIOS and then set the Boot Order for IPv4 and IPv6. Let me know if you need further help. Regards, David V Intel Customer Support Technician Under Contract to Intel Corporation

Hi David,      Thank you for your reply. I unchecked "Boot network Devices Last". Tried first ipv4 higher in the list, and then ipv6 higher in the last, each time the system boot ipv6 first. Dalton

Hello DZhan20, Thank you for your response. This is the expected behavior due to IPv6 having a higher priority, that is why it always goes before IPv4 in the boot order. Regards, David V Intel Customer Support Technician Under Contract to Intel Corporation

David,       Did I already perform your work around, or "uncheck" and "disable" are not the same thing (for Boot network Devices Last)? Dalton

Hello DZhan20, Thank you for your response. My apologies but I do not understand, are you asking if "uncheck" and "disable" for boot network last is the same thing? As a workaround you can try both and see which works for you; however, keep in mind that as mentioned above, the system decides to go with IPv6 first because it has higher priority and it is expected.
