Subject: [Qemu-devel] [PATCH] sparc: Set HostID in NVRAM
Date: Mon, 30 Dec 2013 00:51:18 +0100	[thread overview]
Message-ID: <52C0B576.6060102@caramail.com> (raw)

On SparcStations, the HostID field in the NVRAM is equal to the
last three bytes of the MAC address (which is also stored in the NVRAM).

This constant is used as an identification/serial number on Solaris.
