I plan on running freedos in a Virtual Machine, so I have an entire Logical Volume set up as a Virtual Image for Freedos to install to. As, to my surprise, apparently Freedos seems to be unable to partition a hard disk from within the installer, I have to somehow get a partition table plus a FAT partition on the Logical Volume. The only way I know of doing that is by using fdisk on the Logical Volume and using kpartx to get Linux to recognize the partition I just put on to it, so I can use mkfs.msdos on it. >> - InitDiskWARNING: using suspect partition Pri:1 FS 06: >> > Partition type 06 is FAT16 non-LBA.
