hodgestructure Posted September 28, 2010 Share Posted September 28, 2010 Following the tutorial by hecabe, http://www.insanelymac.com/forum/index.php?showtopic=151861 I have made a working Snow Leopard 10.6.4 LiveDVD. But I want to do something more. Grub4dos has a feature called "ISO emulation", by which one can boot from iso directly. When I boot my computer, I got grub4dos menu, then I typed the following commands: title Snow Leopard LivDVD ISO map --mem (hd0,0)/ISO/Mac-Live.iso (hd32) map --hook map (hd32) (hd0) #with this line or without chainloader (hd32) boot it continues to boot from Mac-Live.iso, but finally it stops with a message "still waiting for root device" , and repeat this message again and again. My question : Is any way to boot directly from Snow Leopard LiveDVD iso? (I think we may modify some files...) The reason for which I want to boot from iso are: 1. I don't have a built-in DVD rom. I tested the LiveDVD by an external DVD rom. 2. Booting from iso is much faster that booting from DVD rom. 3. I can use LiveUSB, but I prefer to use LiveDVD iso, because I like grub4dos. With ISO emulation, I don't have create many partitions. (I have many bootable ISO, for example, BartPE, Win7PE, Ubuntu...etc) Link to comment Share on other sites More sharing options...

With ISO emulation, I don't have create many partitions. (I have many bootable ISO, for example, BartPE, Win7PE, Ubuntu...etc) won't work. if you read document of grub4dos , you will find out why. The CDROM emulation (virtualization) Like normal disk emulations, the CDROM emulation also (mainly) works with real-mode OSes. After a protected-mode OS kernel (such as WinNT/2K/XP/VISTA/LINUX) gains control, the OS would have no ability to access the virtual CDROM through BIOS int13. This way NOT work until someone write a driver for MacOSX , like FiraDisk for windows Link to comment Share on other sites More sharing options...
