I don't know the technical = details. (VirtualBox didn't like it, but maybe it's a trivial fix.) I would guess it uses ISOLinux plus some voodoo hackery the same as = various Linux distros which do the same trick. For work I have made a FAT32 USB stick which uses syslinux to load an = MFS containing the loader & kernel and sysinstall then reads the install = files off FAT32.

In theory the loader can read off FAT32 so the kernel could go onto the = flash drive too, however I couldn't get it to work :( -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
