Got this and reading. Can you confirm my summarization: There is no specific default .ins file. IPL-ing by CDROM cannot be made automatic (short of reprogramming the HMC system, I suppose). Someone has to pick the specific .ins file to be used. And then, the CDROM is not available as a data device. But what if a 4th file is listed? Would that file be readable as the 4th tape file on the emulated tape? If a 4th file is not supported, one could use the rootfs feature in place of the initrd feature, and load system install code there. Hopefully, the kernel loader won't do a 3rd file read from the tape in case of no initrd (the parm file would say this ... and I'm not above a little code hacking). Then the early userspace code would run from rootfs via /init and proceed read that 3rd file from tape to extract even more files in some format like bzipped tar/cpio. My goal is to build a multi-arch Live CD (sans X) for administrative use, e.g. typically a rescue CD, but some variant purposes could also be done. I already can do this for PC/x86 and Sun Sparc. I want to add S/390 and PPC capability (all one one CD). This Live system would NOT need the CD at run time (so this limitation in the HMC would be moot); everything would be loaded into rootfs/ramfs (40 MB to 150 MB depending on version). So anyway, this looks like it's doable except that it has to be done on a manual interactive basis for S/390, unless the HMC can somehow be programmed to automatically IPL a specific .ins file upon unattended power-up. -- ----------------------------------------------------------------------------- | Phil Howard KA9WGN | http://linuxhomepage.com/ http://ham.org/ | | (first name) at ipal.net | http://phil.ipal.org/ http://ka9wgn.ham.org/ | ----------------------------------------------------------------------------- ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
