Refer to 107.Pa /usr/share/examples/etc/defaults/make.conf 108for a list of recognized 109.Va CPUTYPE 110options. 111.It Va CCVER 112.Pq Vt str 113Controls which GCC version to use by default. 114It should be set as 115.Li CCVER?= 116so as not to interfere with overrides from userland. 117We currently recommend that an override NOT be set in 118.Pa /etc/make.conf . 119Currently accepted values

pxeboot 8 314loader retrieves the kernel via NFS. 315Defining this and recompiling 316.Pa /usr/src/sys/boot 317will cause it to retrieve the kernel via TFTP. 318This allows pxeboot to load a custom
