Booting FreeBSD with Syslinux
Hi, I am trying to make a FreeBSD 9.2 hybrid image (ie ISO USB from the same file) and as part of that I need to use syslinux. Unfortunately I can't get Syslinux's mboot.c32 to run the kernel or loader as suggested at http://www.syslinux.org/wiki/index.php/Mboot.c32 - it reports Invalid Multiboot image: neither ELF header nor a.out kludge found. I suspect I would be able to use memdisk as I have used that in the past with syslinux (for 7.x) however this was seems a lot cleaner and easier to generate. Has anyone had any success with this? Thanks. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C signature.asc Description: Message signed with OpenPGP using GPGMail

I have not worked with Syslinux, but I do load a customized FreeBSD 8.x bootonly ISO via memdisk. I have not done similar with 9.x yet, but anticipate doing so with 9.2-RELEASE.

I suspect I would be able to use memdisk as I have used that in the past with syslinux (for 7.x) however this was seems a lot cleaner and easier to generate. Has anyone had any success with this? Absolutely. You can download and dissect the following to show you how it's done... http://druidbsd.sourceforge.net/download.shtml#FreeBSD_Druid It uses syslinux, as you can see here: http://druidbsd.cvs.sourceforge.net/viewvc/druidbsd/druidbsd/druid/src/boot/freebsd/isolinux.cfg?revision=1.1view=markup As you can see, I use the memdisk.c32 module. Notice that I append iso raw as options to memdisk.c32. You may then be asking yourself... if the thing to do is to use memdisk with an ISO... what's in said ISO? http://druidbsd.cvs.sourceforge.net/viewvc/druidbsd/druidbsd/druid/mdroot/ Basically... 1. Kernel 2. Boot Forth 3. mfsroot All that goes into an ISO. When memdisk initiates the ISO, /boot/cdboot then gets invoked. From there, /boot/loader gets invoked. From there, the /boot/loader.rc is loaded. From there, loader.4th is loaded. From there, loader.conf is loaded. In a normal FreeBSD boot process, then the kernel gets loaded (I've modified that to not load the kernel until later -- because my Forth boot menu presents a kernel selection option) From there, beastie.4th is loaded. From there, beastie-start is called and then the beastie menu is drawn. NOTE: I've skipped a whole bunch of other Forth modules that were loaded at-once indirectly From there, the user makes any boot option choices, and presses ENTER to boot. From there, mfsroot.gz is loaded. From there, /stand/sysinstall gets invoked. From there, /install.cfg gets invoked. From there, /stand/fis gets invoked. From there, /dev/iso9660/druid gets mounted onto /cdrom (this ISO9660 volume is actually _not_ the ISO that memdisk booted, but rather this is the actual CDROM (or DVD) that you booted from (which contains both the syslinux boot loader *and* the ISO it booted *and* anything else you want to access). At this point, /cdrom is your ticket to freedom, busting out of the double-encapsulation (first encapsulation is wrapping the kernel+forth+mfsroot into an ISO, second level of encapsulation is from within the mfsroot; from within the mfsroot, the GEOM provided /dev/iso9660/VOLID is an escape hatch to the level *above* the ISO the mfsroot was embedded within). -- Devin _ The information contained in this message is proprietary and/or confidential.
