Hi,

 

Just for the heck of it (to test the hdmi port, in Freedos with a Windows host), I installed VirtualBox on a Windows 10 PC.

 

No problem with the initial steps, I assigned 64 mb of memory, and 500 Fixed Sized mb for a VHD virtual hard disc.

 

System/Processor/Execution Cap is set at 40%.

 

Network Attached to Nat

 

 

 

But neither the CD Rom http://www.freedos.o...load/FD12CD.iso file nor the USB version http://www.freedos.o...ad/FD12FULL.zip seems to work.

 

 

The USB version:

 

This consists of a FD12FULL.img, FD12FULL.vmdk, and README.md.

 

The problem is, VirtualBox doesn’t support these formats, as far as I can tell.  The only file extensions is recognizes are .iso, .cdr, .cue.  So it's not clear how to use this.

 

 

The CD Rom file:

 

There’s no CD Drive on the laptop, but I tried just putting the ISO in a folder on an already bootable USB Freedos, and pointing there. 

 

It seems to work, at first  There’s the

 

    Welcome to FreeDOS 1.2

 

welcome screen, with the menu items

 

    Install to harddisk

    Boot from system hardisk, etc.

 

I try Install to harddisk, and it starts giving me a loooooong list of Invalid Opcodes.

 

 

Has anyone installed FreeDos inside VirtualBox, with the USB file?  The instructions at http://wiki.freedos.....php/VirtualBox assume we’re using the CD Rom file.

 

 

Regards,

Ok, I got past the Invalid Opcodes, using the sidebar instructions at http://www.freedos.org/download/.

 

But I'm a little nervous about the next step.  The Freedos install says that Drive C: does not appear to be partitioned, and whether I want to partition it.

 

It is referring to a VirtualBox partition, or my C: Drive?  I haven't backed up my Windows 10 PC in about a month and a half.

 

Update:  I selected to 'Return to Dos', rather than create a partition, and it seems to work fine.  I haven't copied & tested any of my Dos tools yet, or connected via hdmi.  I'm sure that will be fine, as well.

 

 

 

However - VirtualBox's 'Full Screen' is not really Full Screen.  It's still just a window, with small fonts.

 

I'll search around the web for a solution to this, and come back here, if no luck.

 

For now, VirtualBox seems to be hosting FreeDOS as expected, except for Full Screen mode.

 

Looking forward to testing the first release of 1.3, hopefully end of November.

 

 

Regards,

The only partition that the FreeDOS session should see is the virtual C drive that you defined as it's disk. 

 

That being said, stop NOW and back up your OS.  If there is any questions whatsoever that any software may harm your base OS then do a full backup immediately, this is just common sense.

No argument, here.  Ok, thanks Rootman.
