boot img like a iso, but..

[z-80a]

Hello!
I want to load a virtual machine image without using iscsi target, like a bootable iso image:

Code:

:iso
initrd ../Win98SE_bootdisk.iso || goto failed
chain ../memdisk iso raw || goto failed
goto start

it works!

It is logical to assume that the raw image (mbr, gpt and other scheme) can not be placed completely in the ramdisk. Maybe I'm wrong and there is a way around it..

Help me, please!
