In the event that you have more than one <a href="https://interviewquestions.tuteehub.com/tag/operating-1136761" style="font-weight:bold;" target="_blank" title="Click to know more about OPERATING">OPERATING</a> system installed on your system (i.e. personal computer, harddrive), System Commander makes it <a href="https://interviewquestions.tuteehub.com/tag/possible-592355" style="font-weight:bold;" target="_blank" title="Click to know more about POSSIBLE">POSSIBLE</a> to choose which one of these operating systems to boot. In this regard System Commander is comparable in overall functionality to software like NTLDR, LILO, GRUB, and Graphical Boot Manager, which also makes it possible to make such a choice at boot time. </blockquote> Does that help any?  <br/>Ok, C++ sources there are, but how complete... neeeds check.<br/><br/>M<a href="https://www.partitionwizard.com/">https://www.partitionwizard.com/</a><br/>Notice there is a free version. Thais software works with Windows 10 and many other systems. It is currently supported. I have only used the free version.<br/><br/>Earlier I said that MS-DOS would destroy a large hard drive. That is not true. Just two days ago I did n experiment and found I could make a small FAT partition on my 500 GB HDD. But it has to be the very first primary and there  to be a MBR on the disk. I boot MS-DOS 6.22 from a CD and can read both the CD and the C: drive. The CD pretends it is A: and MS-DOS seems to like that.<br/><br/>I do not know if the partition manager can boot DOS from my hard drive. Id o not want to try.I think it is safer to just boot from the CD drive. As I recall, I put it on a mini CD and it worked because MS-DOS 6.22 does not take much space at all.<br/><br/>Here is some more info about how this is done:<br/><a href="https://www.experts-exchange.com/questions/20389455/Making-a-bootable-dos-6-22-cd.html"><br/>Make a Boot-able MS-DOS 6.22 CD.</a><br/><br/>Have fun!  <br/>I found solution in other topic.<br/>Really I need not optical drive - like CD, DVD or other.<br/>I wnt to put to place of DVD drive else one harddisk - this solves all.<br/>Why:<br/>HDD1<br/>1.

And if you do, a small portable drive on USB will work for the few times yu need it.<br/><br/>To boot DOS, it must be first primary and use FAT but not FAT 32.<br/>Older DOS versions can not read FAT 32. And older DOS can not read beyond 8GB. That is why you want it to be first on the drive.<br/>Here it needs note - I'm using MS-DOS 7.10 with FAT32 support, older versions not. DOS 7.10 has many benefits, so I decided for.<br/><br/>MiroGood choice.<br/><em>I named DOS 6.22 because it was the last stand alone DOS for Microsoft. </em><br/>And it was the last that ran or pre-386 computers.<br/>MS-DOS 7 and other versions <a href="https://interviewquestions.tuteehub.com/tag/require-11720" style="font-weight:bold;" target="_blank" title="Click to know more about REQUIRE">REQUIRE</a> a 32 bit CPU.<br/>Here is a site that gives user support for a modified version of MS-DOS 7.10 :<br/><a href="http://dosworld.czweb.org/">http://dosworld.czweb.org/</a><br/>Most of it is in English.<br/><br/>That links provides really limited support, even two links are dead.<br/>Nice is that it has also Czech comments - I'm from Slovakia and know Czech language perfectly - we were Czechoslovakia... <br/><br/>MiroGlad you found it.  <br/>They are active and can offer support.

(reply #3 and #4).<br/><br/><br/> Quote<blockquote>And it was the last that ran or pre-386 computers. MS-DOS 7 and other versions require a 32 bit CPU.</blockquote> <br/>But... They have an Intel Mac, as evidenced by being able to run Linux Mint... Which also requires a 32-bit CPU....<br/><br/><br/>In any case, I think both OS X and the Apple Firmware for the system are likely to be the thing throwing up most of the barriers to dual booting these systems. OSX, Bootcamp, and the Firmware as I <a href="https://interviewquestions.tuteehub.com/tag/understand-720010" style="font-weight:bold;" target="_blank" title="Click to know more about UNDERSTAND">UNDERSTAND</a> it work together to allow booting other systems and if the system came with 10.4 than that was all in it's very early stages.</body></html>
