Problem

Stone / Asus Skylake and Kabylake systems with certain BIOS revisions may not be able to be reimaged using a PXE server when the PXE server is on a remote subnet. Typically in this situation your infrastructure uses IP Helpers so that the client PC can reach the PXE server, and does not use DHCP option 67.

When the problem occurs, you can see that an IP address is assigned to the client, but then the PC says "No offer received" in relation to the PXE request.

This issue predominately affects customers using UEFI PXE boot using IPv4.

Cause

This issue has been caused by a BIOS problem with some 3xxx BIOS versions on the products listed in the table below.

If you are experiencing these systems, to confirm if you are affected by this issue, test your PXE infrastructure by imaging a different PC that has an unaffected BIOS revision.

Resolution

Upgrade your system to a later BIOS.
