It's derived from Patrick's code and I finally see good responses with a VMware VM's e1000e NIC (never saw ANYTHING good from it until now). git://github.com/geneC/syslinux.git https://github.com/geneC/syslinux.git -- -Gene <<< Hi there I think in the case of a particular

...m also trying to fix this bug but unfortunately I'm not having much time. This is the approach I'm going to try: 1) detecting the right NIC at pxe.c\net_parse_dhcp(void) (as you do) 2) saving its associated MAC address. 3) at main.c\efi_create_binding() (let's consider the UDP case) LibLocateHandle() returns the handles of the devices that publish a EFI UDPv4 Service Binding Protocol GUID. Each device with a published EFI UDPv4 Service Binding Protocol GUID supports the EFI UDPv4 Protocol and may be available for use. Considering a "Device Path Protocol" is attached to device handl...

Hi All, My PXE configurations works fine for a bios PXE (the server in legacy mode) but hangs in an EUFI mode. Look like it can transfer the bootx64.efi but not the next one ldlinux.e64 Any ideas?

Starting a new thread for the moment and BCCing the two reporters of the issue. Looking over the code, I think I finally see why we get junk data from the PXE base. If we tell the PXE base that a buffer is 0 bytes long, we should expect junk/null data. I'm hoping to have a patch for testing over the weekend. If either of you would rather start a bug on the bugzilla, feel free. -- -Gene
