What I want to do is set it up on a CDROM so it would be bootable from the CDROM. I read the docs on the files for emulating tape from files, either one big file for a whole multi-file tape, or file-per-file. What was not said was specifically what name is looked for in actual IPL-ing, or how it knows which name. I do know how x86 PCs and Sun Sparc machines boot. And I do know how mainframes IPL from "normal" devices like DASD, TAPE, CTCA. I would have originally guessed that CDROM would work like DASD, but the docs say its a set of files instead of a set of sectors, so it must be more like El Torito than it is like how Sun Sparc boots. I can probably figure what I want to know from instruction steps to build a bootable CDROM from these 3 files. But I tend to prefer having info in the form of "here's how it works" rather than "here's what to do" (makes it easier to adapt to doing different things). FYI, my intention is to build a bootable ISO image with a subset of Linux that can boot from several architectures. I already have x86 and Sparc on a single CDROM. It looks like I could add S390 if it doesn't need to use the first 3 sectors. PPC will be my next target and that may conflict with Sparc, so I may end up with S390/SPARC/X86 and S390/PPC/X86 disks. But if possible, I'm definitely shooting for an S390/PPC/SPARC/X86 disk (fitting all three or four into a 170 MB mini-CD will then be the next challenge). -- ----------------------------------------------------------------------------- | 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
