Overview

Octet “n” gives the number of octets containing “architecture types” (not including the code and len fields). It MUST be an even number greater than zero. Clients that support more than one architecture type MAY include a list of these types in their initial DHCP and PXE boot server packets. The list of supported architecture types MAY be reduced in any packet exchange between the client and server(s). Octets “n1” and “n2” encode a 16-bit architecture type identifier that describes the pre-boot runtime environment(s) of the client machine.

See rfc4578 for full details

The code for this option is 93, and its length must be an even number greater than zero.

The default payload for this option is $DHCP_CLIENTARCH_I386
