Newer S/390's are run from the HMC, (Hardware Management Console).
The HMC is just an OS/2 box, and, as such, also has a CDROM.
The CDROM used to be used to install/upgrade Microcode.
G5 and upwards can also IPL from the CDROM.
I've forgotten the incantation to wade through the panels,
(don't have access to an LPAR Console at home, and a P/390 doesn't support this)
but when you get there, you can tell it to read and IPL from a file such as
* Red Hat Linux for S/390 Installation
This will load the tape_kernel, parmline and initrd and put them
where ever you want them to be in memory.
Thanks and cudo's to jj for adding this to Hercules.
mdz: I'm working on a debian CVS copy from 'boot-floppies' on the
documentation for the S/390-Port, and am trying to understand how the
Debian CDROMs are generated for a distribution, so that we can add this
as an 'accepted way of IPL'ing' into a new/rescue Debian/390 installation.
