This mail obviously was meant to end up on debian-cd, but I guess the BTS is not quite smart enough for that :-( ---------- Forwarded Message ---------- Subject: Bug#318021: Debian/S390 cd-based install image Date: Sunday 07 August 2005 16:04 From: Frans Pop <aragorn@tiscali.nl> To: 318021@bugs.debian.org, control@bugs.debian.org reassign 318021 debian-cd tags 318021 + patch thanks Attached is a patch that will allow to create "bootable" CD images for S/390. Basically it is a revival of code that was already present in Woody, but for some reason was dropped for Sarge. The patch has been tested by creating a CD and booting it from the Hercules emulator. Some remarks ------------ Although the patch allows to boot from CDROM, the installation is still basically over the network. Therefore it is not very useful to build daily netinst-like images. Having bootable CDs only makes sense for full CDs, so either the weekly builds or official builds. Unlike other daily installer images, the images for S/390 are not available on p.d.o, but on lophos.multibuild.org (managed by waldi). If you have a problem with retrieving images for weekly full CDs from there, please let us know so we can try to find a solution. I have not tested an official build. It would be nice if that could be done. Cheers, FJP -------------------------------------------------------

+About the S/390 installation CD
+===============================
+
+It is possible to "boot" the installation system off this CD using
+the files provided in the /boot directory.
+
+Note that the /boot/d390oco.* files are only provided as an example
+as Debian cannot ship the object-code-only-modules-ramdisk (oco.bin).
+
+Although you can boot the installer from this CD, the installation
+itself is *not* actually done from the CD. Once the initrd is loaded,
+the installer will ask you to configure your network connection and
+uses the network-console component to allow you to continue the
+installation over SSH. The rest of the installation is done over the
+network: all installer components and Debian packages are retrieved
+from a mirror.
+
+
+Tip for users of the Hercules emulator
+--------------------------------------
+If you want to ipl the installer off this CD, mount it on the host
+system (e.g. on /media/cdrom) and enter the following in the Hercules
+management console:
+ ipl /media/cdrom/boot/d390.ins
