We use FreeLDR for the RAM booting, which loads in RAM an ISO (not a HDD image yet).<br> For the LiveCD for example, the following lines can be added into freeldr.ini:<br> <br> [Operating Systems]<br> ...<br> LiveCD_RamDisk="LiveCD in RAM"<br> ...<br> <br> [LiveCD_RamDisk]<br> BootType=Windows2003<br> SystemPath=ramdisk(0)\reactos<br> Options=/MININT /RDPATH=livecd\livecd.iso /RDEXPORTASCD<br> <br> FreeLdr will load the "livecd\livecd.iso" file from the boot drive (a USB key for example...) (the switch '/RDEXPORTASCD' explicitely specifies that the file is loaded as an ISO image, with read-only access, etc...).<br> Then, "ramdisk(0)\reactos" specifies that the kernel etc... will be loaded from the "reactos" directory inside the root directory constituted by the ramdisk, once the ramdisk is loaded.<br> <br> <br> Regards,<br> Hermès
