Years ago I wanted to install Fedora which was distributed as a DVD but I had no DVD burner... So, I developed the technique to copy the iso to my boot partition, copy the selected vmlinuz and initrd.img from the distro isolinux directory, and run vmlinuz with the associated anaconda initrd.img, and Voila! Fedora comes to life. The syslinux stanza looks like this:
LABEL Install MENU LABEL ^Install / Upg Fedora-16 KERNEL /Fedora/16/isolinux/vmlinuz INITRD /Fedora/16/isolinux/initrd.img APPEND lang=en_US keymap=us
Recently I tried this with other iso images with mixed success. CD iso represent little trouble since they are small enough that MEMDISK seems to have no trouble with them. So the syslinux stanza looks like this:
LABEL UBCD-Pro MENU LABEL Ultimate Boot CD (XP-Pro.SP2) KERNEL /syslinux/memdisk INITRD /iso/UBCD4Win-XP.Pro.SP2/UBCD4Win-XP.Pro.SP2.iso APPEND iso raw
And in fact what you see above will "boot" meaning I get the menu provided by UBCD, and I can select items, and I can even get the XP splash screen, but it blue screens, which I assume is UBCD paging in from the wrong device, but I don't really know. For comparison, this image does work perfectly if I burn it to optical media. Does anybody have any insight into what is happening to UBCD after I boot the iso with syslinux from my disk and select the UBCD menu item he provides and he subsequently blue screens?
Thanks for the help,
