====== Issues ======

===== Problem =====
Running /bin/Fatfsys on QNX 4 virtual machine would cause the virtual machine to crash.

===== Cause =====
The cause was having the BIOS on the virtual machine having a floppy drive when the vmware server did not have a floopy drive configured.  

===== Solution =====
  Select F2 on boot to get into BIOS
  Disable the floppy drive in the BOIS and save changes.
  Disable the floppy drive controller under the advanced tab.
  Boot the system with new BIOS configuration.

===== Problem =====
To get Dell Latitude D600 laptop to boot QXN4 once installed.  

===== Solution =====
Solution was finally found using Google. See http://groups-beta.google.com/group/comp.os.qnx/browse_frm/thread/23a17045b40600f/9fdc861a329fea84?q=QNX+4+Dell+Latitude+Laptop&rnum=4&hl=en#9fdc861a329fea84

The solution was to execute the command "dinit -h -O -b" from a shell after installing QNX4 and before the final reboot of the system. You can get a shell by moving the install window (the one that allow you to reboot the computer after installing the OS) out of the way and right clicking to bring up a Shell window.
