+Retro UNIX 386 v1.2 disk UMOUNT/MOUNTH principle:
+(fd0, fd1, hd0 must be set in QEMU or VIRTUALBOX or BOCHS)
+
+fd0.img has the /etc/init file which mounts /dev/fd1 into /usr at startup
+if the boot disk is not /dev/hd0, it is mounted as ..
+  umount /dev/fd1
+  mount /dev/hd0 /mnt (or "mount /dev/hd0 /usr")
+If the boot disk is /dev/hd0, /dev/fd1 (or /dev/fd0) is mounted as ..
+  (umount /dev/fd0)
+  mount /dev/fd0 /mnt (or "mount /dev/fd0 /usr") or
+  mount /dev/fd1 /mnt (or "mount /dev/fd1 /usr")
+
+  umount and mount give "OK" message if there is not an error.
+  after umount, mounting directory (/usr or /mnt or any) returns to its normal/own content.
+  (In Retro UNIX v1.2, only one additional disk can be mounted under a sub directory of the root disk,
+   anotherone can be mounted after the previous is unmounted. Disks must have Retro UNIX v2 fs.
+   UNIXCOPY, UNIXFDFS, UNIXHDCP, UNIXHDFS .COM/DOS programs are used to prepare these RUNIX v2 FS disks.)
+
+Startup:
+     boot: unix
+when you see "Type ENTER to start in multi user mode ..." message,
+     press ENTER key.. then write login name as "root" at (tty0) login prompt.
+     (you can use pseudo TTYs, by using ALT+F1 .. ALT+F8 key combinations)
+     change screen to tty1 (via ALT+F2 key) than write login name as "erdogan" and then
+     press ENTER and just after you see password prompt, write password as "417".
+    (/etc/motd message will appear and the shell (/bn/sh) will be launched by /etc/init.)
+    ((tty09 -> COM1, tty10 -> COM2, terminal emulation program is in A.IMG file -SERIAL6.COM-.
+      If any 2 computers -one of them must run DOS SERIAL6.COM other one must run RUNIX v1.2- are connected to eachother
+      via their serial ports, RUNIX v1.2 will run as a server in text mode -only-, tty09 or tty10 will be the DOS user's terminal.)) 
+
+(Basic commands -ls,cd,cp and others- are used as in UNIX v1)
