Many thanks Steffen and Merlin for your configuration details! I learned a lot already and I believe that we are on the right track.
I included your suggestions into my dhpcd.conf . According to the log output below it seems to select the correct file now. But I still could not yet get it to work correctly. In order to debug this I increased the tftpd verbosity level. And this is what I now get in daemon.log when I try again: Dec 3 11:31:34 sysadm02 dhcpd[12875]: DHCPDISCOVER from 50:9a:4c:43:c1:b7 via ens9 Dec 3 11:31:34 sysadm02 dhcpd[12875]: DHCPOFFER on 10.250.217.16 to 50:9a:4c:43:c1:b7 via ens9 Dec 3 11:31:37 sysadm02 dhcpd[12875]: DHCPREQUEST for 10.250.217.16 (10.250.217.102) from 50:9a:4c:43:c1:b7 via ens9 Dec 3 11:31:37 sysadm02 dhcpd[12875]: DHCPACK on 10.250.217.16 to 50:9a:4c:43:c1:b7 via ens9 Dec 3 11:31:37 sysadm02 in.tftpd[13050]: RRQ from 10.250.217.16 filename fai/syslinux64.efi Dec 3 11:31:37 sysadm02 in.tftpd[13050]: tftpd: read: Connection refused Dec 3 11:31:41 sysadm02 in.tftpd[13052]: RRQ from 10.250.217.16 filename fai/syslinux64.efi Dec 3 11:31:41 sysadm02 in.tftpd[13052]: tftp: client does not accept options Dec 3 11:31:41 sysadm02 in.tftpd[13053]: RRQ from 10.250.217.16 filename fai/syslinux64.efi 10.250.217.16 is the installation client. Any idea which read failed for tftpd ? The syslinux files all are mode 644, so they are readable. Directories are 755. What may refuse the connection for tftpd? The "client does not accept options" does not express a problem. This message also appears when the install boot is successful (in legacy BIOS mode).
