<br>
I've been using FAI for years now, and could always avoid UEFI - until last<br>
week when a coworker asked me to "quickly" run a sysinfo for one of his new<br>
machines.<br>
Of course, it comes with UEFI activated.<br>
After finding how to distinguish between BIOS and UEFI PXE requests, and<br>
setting up the DHCP/TFTP server accordingly, it was only "yet another step"<br>
to find and add ldlinux.e64 to get the machine booting.<br>
It requests the kernel, and loads it.<br>
It requests the initrd, and hangs doing so.<br>
/var/log/daemon shows both requests and nothing more after them.<br>
<br>
There's a warning<br>
"core_udb_sendto: stalling on configure with no mapping"<br>
further up the boot screen, but I'm not sure it'd be related.<br>
<br>
The corresponding pxelinux.cfg file was created once, worked in legacy mode.<br>
<br>
Unfortunately, UEFI-related FAI documentation is very sparse, and I may have<br>
overlooked something?<br>
Machine is a Dell one (if this makes a difference), PowerEdge R840.<br>
<br>
Fortunately, the machines were able to boot in legacy mode, so the goal was<br>
reached to a major extent (I couldn't test EFI detection though, not run<br>
"efibootmgr -v" within one of the class scripts).<br>
<br>
<br>
Any suggestions what to try next?<br>
<br>
Thanks,<br>
Steffen<br>
