Ubuntu - /var/log/message ?

網路找了一下.才發現.原來到了Ubuntu 11.04 後.
就已經改到 /var/log/syslog 

UEFI + Legacy PXE server

adding those two to your  dhcpd.conf

# vim /etc/dhcp/dhcpd.com

option arch code 93 = unsigned integer 16

if option arch = 00:00 {

      filename "pxelinux.0";

} else {

      filename "BOOTX64.efi";

}
