Description

This contrib supplies the basic parameters for dhcpd to allow pxe booting on your network.

service dhcpd restart

This will update your /etc/dhcpd.conf file to include

option client-architecture code 93 = unsigned integer 16;

<and within the subnet scope>

    if option client-architecture = 00:07 {
        filename "/bootx64.efi";
    }
    elsif option client-architecture = 00:06 {
        filename "/bootia32.efi";
    }
    else {
        filename "/pxelinux.0";
    }
