"PXE-E3A: TFTP too many packages"

SYMPTOM

When being started, the PXE client comes up with the PXE copyright message and completes the DHCP phase, but then displays:

PXE-E3A: TFTP too many packages

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.

CAUSE

The "PXE-E3A" error indicates that the PXE client tried to download a file via TFTP, but found that this file was actually larger than the buffer that was allocated for it. This problem may occur when TFTP option negotiation between the PXE client and TFTP server fails.

RESOLUTION

Check the TFTP server log for error or warning messages. Use a TFTP server that supports TFTP option negotiation. Update the PC BIOS, PXE code and/or TFTP Server software to the latest version.
