>>> Using VMware I built a test setup of a server with dhcp, tftp and a http-server and several pxe-clients with EFI mode turned on. This setup worked, albeit with the exponential-like decay of IO rate I described earlier. The work-around of using HTTP works beautifully though. <<< ""exponential-like decay of IO rate"" could you please post a link on

Hello, I can't help with the problems on real hardware but have come across the qemu problems before and maybe I can give some hints on that.

Sure, see the thread starting at: http://www.syslinux.org/archives/2015-June/023621.html And Gene's confirmation at: http://www.syslinux.org/archives/2015-June/023629.html > OK I got lost. > are you saying you finally

In another mail I discussed my adventures on netbooting syslinux 6.03 and newer from iPXE, either from an emulated rom on qemu/kvm/ovmf or by chainloading via ipxe.efi onto a real HP Proliant DL360 gen9 piece of iron. You might have asked yourself, why chainload? Why not load it directly? Believe me, i tried. First I had to 'fix' my dhcpd.conf because HP probably read the docs on

Hello. I played with UEFI PXE booting the other day, and as usual, used qemu/kvm virtual machine for initial testing/debugging, because it is way easier and faster for this task than using a real hardware. However, it looks like either qemu or {pxe,sys}linux 6.03 is buggy, -- the two does not play well together. When booting, the system successfully loads syslinux.efi, at least the tftp server

Hello, I'm trying to find out how to pxe boot with syslinux.efi on QEMU with OVMF. After getting through the initial hurdle caused by the iPXE based option ROM included with QEMU having a problem as described in these threads: http://www.syslinux.org/archives/2014-November/022804.html http://sourceforge.net/p/edk2/mailman/message/33236100/ I'm now getting further to almost being able

Hi Apologies for referring back to an old thread, but in this conversation https://www.syslinux.org/archives/2018-October/026198.html Thomas and Ady seemed to suggest that booting 32-bit linux from 64-bit EFI was possible with the patched 6.04-pre version of syslinux that Debian are using. When I try this, all I get is Loading ../../bzImage...ok Loading ../../imgpt4.gz...ok and then nothing.

Hello, First, this setup works fine without any error in syslinux 4.06 as show below. For convenience, both versions of syslinux 4.06 [#1] and 5.10 [#2] directories (~2MB each) are uploaded ready for test. As said before, this is tested on qemu-1.5.0 + dnsmasq 2.66 in Arch Linux @ 64-bit. If more info is needed, please let me know. Good luck! Relevant directory structure is at
