It's been a while since I have had any time to work on one of my pet projects...

So, herewith, step 1 in it: a downloadable FAT32 PC-DOS 7.1 Virtualbox disk image.

This is the PC DOS 2000 disk image from Connective VirtualPC – I described how I created that this time last year.

I've replaced the kernel files, COMMAND.COM and a few utilities with those from the freely-downloadable PC DOS 7.1 made available by IBM. I've described that and how to get it, too.

So what I did was make a new FAT32 8GB virtual drive. Partitioned it with PC-DOS 7.1's FDISK32 command. Formatted it with PC-DOS 7.1's FORMAT32 command. Copied the system from the Connectix FAT16 drive, check it boots, and here it is.

Next planned step: add in the IBM Warp Server DOS LAN Services & IBM TCP/IP and make it able to talk to the VirtualBox host. Sadly, after so long away from this, it took me some hours to remember where I was up to and build this disk image.

SYS.COM does not know about FAT32, although it can be used to prepare a bootable floppy
disk. PC-DOS 7.10 will boot from a generic PC-DOS boot-sector.

Patched SYS.COM, without it sys commands, ie "a:sys:", will report "incorrect DOS version", with it sys commands will work correctly as PC-DOS 7.1 Rev 0 BLD134

I have uploaded a patched version here:
