PXE is most sought after way (wonder why). In a network with mix of x86 and arm servers, it would be a pain to manage pxe boot. One needs to have special rules in dhcpd config to separate out the 2 archs. I believe the present way is the TFTP server points to a netboot or pxelinux efi binary (from syslinux) and then it uses NFS to do the installation. So if this binary is arch specific it will pose a problem in multi-arch environment. Now if I want to launch a different binary I have to go edit the dhcpd.conf (only if I manage the network). I understand its kind of developer thing. But having an option for developers to enter the server and file name is a more straight case in my opinion if you are making a good software. > > This library can download a file from a TFTP remote using the PXE Protocols. > The same way an OS loader can use UEFI services to load more info. > https://svn.code.sf.net/p/edk2/code/trunk/edk2/EmbeddedPkg/Library/EfiFileLib/EfiFileLib.c > > Thanks, > > Andrew Fish > > > > Best Regards, > Ye Ting > > -----Original Message----- > From: Leekha Shaveta [mailto:shav...@freescale.com] > Sent: Tuesday, June 23, 2015 1:15 PM > To: edk2-devel@lists.sourceforge.net > Cc: Olivier Martin > Subject: Re: [edk2] PXE with manual TFTP server and filename options > > Hi, > > Then how tftp and PXE boot flow works in UEFI network stack? > How to provide server ip address and file to get from remote location? > > Thanks and Regards, > Shaveta > > -----Original Message----- > From: Ye, Ting [mailto:ting...@intel.com] > Sent: Tuesday, June 23, 2015 8:48 AM > To: edk2-devel@lists.sourceforge.net > Subject: Re: [edk2] PXE with manual TFTP server and filename options > > This is not supported by UEFI network stack as I known. > > Best Regards, > Ye Ting > > -----Original Message----- > From: Radha Mohan [mailto:mohun...@gmail.com] > Sent: Tuesday, June 23, 2015 9:12 AM > To: edk2-devel@lists.sourceforge.net > Subject: [edk2] PXE with manual TFTP server and filename options > > Hi, > I am looking to do PXE boot with an option to manually enter a TFTP server > ip address and filename from the prompt. > This option can help in having a multiple installation of distros at > different locations. > Is this something that is already available or on the cards ? > > regards, > Radha Mohan > > ------------------------------------------------------------------------------ > Monitor 25 network devices or servers for free with OpManager! > OpManager is web-based network management software that monitors network > devices and physical & virtual servers, alerts via email & sms for fault. > Monitor 25 devices for free with no restriction.
