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)

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
