@wimb: looks like an adventure. i will take it if PLoP fails. thanks! @jaclaz: well, i downloaded and installed PLoP v5.0.10 and it's up and runnning. but i can't figure it out how to load an iso file into ram using PLoP for installation onto external usb. maybe, you misunderstood something? referring to plop.at, PLoP can't do that. you could install PLoP using a floppy/iso image, but not use it to install another OS from ISO. any easy to realize idea? thanks
