535    (MIPS64) CPU, add <tt><b>-C 4Kc</b></tt> to the command line. With NetBSD
536    2.0.2, however, there will be little or no difference in functionality.

731    For example, when NetBSD says "<tt>nfs_boot: trying DHCP/BOOTP</tt>",
732    there will be a long pause, even on a very fast host machine. The reason
733    for this is mostly because the emulator doesn't deal with timing issues
734    very well, but also because NetBSD tries IPv6 first, before falling back
735    to IPv4.
