I'm running Xubuntu 12.10 on my Asus Zenbook UX31e. Zenbook is shipped within an Asix USB ethernet dongle. Here some information.

   description: Ethernet interface
   physical id: 2
   logical name: eth0
   serial: 9c:eb:e8:01:96:59
   size: 100Mbit/s
   capacity: 100Mbit/s
   capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation
   configuration: autonegotiation=on broadcast=yes driver=asix driverversion=22-Dec-2011 duplex=full firmware=ASIX AX88772 USB 2.0 Ethernet ip= multicast=yes port=MII speed=100Mbit

I've set up a working PXE, but unfortunately it doesn't work for only my zenbook. The BIOS, as soon as the dongle is attached, allows to enable boot from network. Once I start it, everything seems to proceed well, the dongle is recognized, an IP is assigned but the process gets stuck when the TFTP location is given. It cannot find the file.

Here what happens:

CLIENT IP: address MASK: 255.2555.255.0 DHCP IP:
PXE-T01: file /srv/PXEtftp/Here appears strange signs
PXE-E3B TFTP Error - File not found
PXE-M0F: Exiting Intel PXE ROM

Why does it behave in this way? Doesn't it simply support PXE?

Usually the NIC should get the list of available kernels trying to match the file name with its MAC address but here that doesn't happen.

Note well that apart PXE the dongle works great.

Thank you for any help!

+1 I am failing with PXE boot over the asix usb-ethenert dongle that came with my zenbook too. I am using a fairly standard dnsmasq setup on debian 7 for tftp/bootp/dns and i have verified that my setup works when booting other computers. At first I thought this was my solution: linuxquestions.org/questions/linux-networking-3/… but it was not. –  Lennart Rolland Aug 29 '13 at 12:24
