| + | If you want to test gPXE but you are using extensively pxelinux and you do not want to break the rest of your configuration, you can add a menu entry to load gPXE. | ||
| + | The ''/etc/dnsmasq.conf'' should contain something like: | ||
| + | #DHCP | ||
| + | domain=mydomain | ||
| + | dhcp-range=192.168.10.100,192.168.10.200,255.255.255.0,30m | ||

| + | # required by old versions of gPXE (e.g. the one that comes with OracleVM) | ||
| + | dhcp-no-override | ||
| + | The ''/tftproot/pxelinux.cfg/default'' should contain: | ||
| + | DEFAULT menu.c32 | ||
| + | PROMPT 1 | ||

| + | LABEL gpxe | ||
| + | MENU LABEL gPXE - chainload gPXE from a PXE capable NIC | ||
