When being started, the PXE client comes up with the PXE copyright message, then displays
After a while, the following error message is displayed:
Depending on the PXE client's system setup boot device list configuration, the PC then either stops or tries to boot from the next boot device in the system setup boot device list.
The "PXE-E53" error indicates that the PXE client received a reply to its DHCPDISCOVER message, but the "boot filename" information was missing in this reply.
Make sure that the "boot filename" option is present on your DHCP or BOOTP server, and that its value is set to the filename of the boot loader.
When using Microsoft DHCP server, add option 067 (Bootfile Name) to your scope. When using a Unix/Linux based (ISC) DHCP server, use the "filename" parameter for this purpose.
In the context of the BootManage Administrator, the boot loader filename is "pxboot" for PXE clients and "bpboot" for TCP/IP BOOT-PROM clients. So, if you have exclusively PXE clients, set the boot filename option to the value "pxboot". If you have exclusively TCP/IP BOOT-PROM clients, set the boot filename option to the value "bpboot". In a mixed PXE and TCP/IP BOOT-PROM client environment, you must configure your DHCP or BOOTP server so that it provides the PXE clients with the "pxboot" boot loader, and the TCP/IP BOOT-PROM clients with the "bpboot" boot loader.
