Why only > RAM disks can be accessible? It can, but not safely. dosemu normally provides a replacement for the DOS file system to safely use the Linux file system in a reasonably compatible manner. You can enable direct hardware access in dosemu.conf for specific I/O ranges, etc, and run dosemu with root privileges to punch a hole through the kernel security & moderation layers, but you should think twice about doing so. If you want to repair a HDD with DOS-based tools, make a bootable CD with fredos on it and use that to run them. Look at 'UNetbootin' for such support. Regards, Paul -- Dr. Paul S.
