Hi! (Forgive me if this is well-answered somewhere, but I did some searching, and did not come upon it.)
I have a Netra T1 running the old Debian sparc port. I wanted to reinstall it with the sparc64 port, but it does not have a cdrom, and I do not seem to grasp how to netboot the Debian installer for this machine. I tried just handing it vmlinux from https://cdimage.debian.org/cdimage/ports/debian-installer/2021-04-17/sparc64/debian-installer-images_20210415_sparc64.tar.gz over TFTP, but that just dies with "fast Data Access MMU Miss" before ever displaying anything suggesting Linux was booting, so that seems wrong. I tried setting up GRUB using the config examples on the wiki, but instead hanging it the vmlinux and initrd.img from the above debian-installer tarball, but it just bails out into grub rescue after printing "error: no DNS servers configured." (and I'm quite confident my DHCP server is giving out DNS servers too), so I presume something is going very wrong. Any pointers or helpful hints would be welcomed. Thanks! - Rich
