Hi,
finally created a LiveDVD ISO automatically booting x86_64 OS on x86_64 (and i686 otherwise). Regular users will not notice there exists any new arch while they will benefit from the full performance of their PC: http://people.redhat.com/jkratoch/x86bilive-2009062000.tar.gz (71KB)
It uses live_dir=LiveOS-x86_64 vs. live_dir=LiveOS-i686 to boot the image.
The syslinux patch provides "default-{x86_64,i386}" keywords in isolinux.cfg.
livecd-iso-to-disk is not patched/compatible with such image.
livecd-creator should create such ISO on a single run, not by merging the output of two livecd-creator runs by a 3rd party app.
Regards, Jan
Reasons:
* I still did not understand why I have to carry with me two media - both x86_64 and i386 - when all the data perfectly fit on a single media.
* Why I have to try to boot x86_64 first to find out if the specific machine is x86_64? Even common programmers do not know it, "Windows XP works here".
* The OS must "just work", it must be fun and easy. Requiring a special technical decision before even starting the OS download is a showstopper.
* Checked that a regular user will on http://fedoraproject.org/get-fedora still download terrible performance degradation of 32-bit OS although her hadware is in 70%-95%(?) of cases x86_64. x86_64 is here for 6 years now.
* Arguing x86 may be faster than x86_64... I did not find any such case, x86_64 is a more modern arch (more registers, PIC for free, better ABI). We already hit the 2GB address space limitations. x86_64 is the future.
* All the friends of mine have 8Mbit+ ADSL and TB disks downloading many DVD disks so some several more hundreds of MB are not something to notice.

It does not make much sense to me, so maybe you can explain it:
Isn't syslinux 3.72 or later itself capable of choosing one or the other menu entry using ifcpu64.c32?
Would that not be a better option?

yes, definitely, my syslinux patch is useless.
I did not expect such option exists when such ISO still has not been released while waiting for it the recent years.

So yeah, the problem we get with i386/x86_64 hybrids is more that we would reduce the available size to either of the Live images to half a CD or half a DVD. Some of our spins fit on half a DVD, but not half a CD. If some spins have separate media for each arch, and others do not, then that may work confusing.
That said though, I don't think we've had this kinda thing discussed or decided upon... so it's a good point ;-)

I think it's safe to assume that attempting to fit any 'real' biarch spin on CD would be a futile exercise. DVD shouldn't be an issue for the non-Games live spins yet, should it?

There ware recent discussions people no longer download CD media; but to say the truth I do not find a clear consensus. BitTorrent downloaders of the split CD sets have been decreasing. F9: 6.32%.

A biarch rescue image would be useful. For some kinds of recoveries you need to use a rescue image matching the arch of the system you are trying to fix. I got bit by this during the F11 devel cycle.

This would actually fit on a CD, too. I'm interested in exploring this.
Would this most suitably fit within the Fedora Project as a spin, or maybe something else (a Fedora 12 Feature??)?

updated it to use ifcpu64.c32, thanks for the notice.
It is currently tested only with F-12 (updated) but it should work with any release. It can take Fedora-12-i686-Live.iso + Fedora-12-x86_64-Live.iso or it can build two such from hypothetical custom Fedora-12-LiveCD.ks.
The previous version created biarch DVD. But one could not easily convert it to USBFlash as livecd-iso-to-disk expects a single directory on the CD/DVD. As CD/DVD are IMO no longer useful as bootable media this script converts:
uni-arch x86_64 CD/DVD + uni-arch i686 CD/DVD -> bi-arch x86_64+i686 USBFlash
Created it now just for my personal needs; there is missing: * Some proper integration with livecd tools. Either * livecd-creator should be able to create biarch CD/DVDs AND livecd-iso-to-disk should convert such biarch CD/DVDs into USBFlashes. or * livecd-iso-to-disk should create biarch USBFlash from two uniarch CD/DVDs. or * livecd-iso-to-disk should be able to update uniarch USBFlash with second uniarch CD/DVD creating biarch USBFlash (=reimplementing this script). * It does not have EFI. Unaware how to test it and when it is needed for x86*. * It is an ugly hack.
Some people may think Fedora should stop producing i686. Unfortunately I still know about two boxes running 32bit only CPUs. (Running i686 on x86_64 box has no technical benefits; besides some easier compatibility with proprietary i686 binaries as I heard about.)

Hi,
I finally could check the output of mkbiarch, which I believed should be the upstreamed variant of "auto-biarch" script posted by me: http://lists.fedoraproject.org/pipermail/livecd/2010-March/005755.html
But it does not serve for the primary purpose at all: Normal user just not touching the boot on an x86_64 box will still get booted the crippled i686 OS. I have checked It does not use ifcpu64.c32 at all so it cannot work.
It also does not provide the "Basic Video" / "Memory Test" etc. options. It also does not provide an option for a fat filesystem on the flash media, together with fitting/specifying media size for an available free space there.
It is neither on-par with the original media nor on-par with "auto-biarch".
Should I convert the "auto-biarch" script into Python or try to merge the features into existing /usr/bin/mkbiarch to get it accepted? This way I am not sure if it still be in time for a meaningful official F15 bi-arch media.
Thanks, Jan

Attaching an updated shell script with these features. Tested with: livecd-tools-14.0-1.fc14.x86_64
Should I convert the "auto-biarch" script into Python or try to merge the features into existing /usr/bin/mkbiarch to get it accepted?
BTW I would prefer Perl which is not available on some LiveCDs but it should be always available on the build system. I do not know if/why EFI support would be needed for such boot-flash. GPT should not be needed on boot-flash.
Thanks, Jan
