I had initially tried all the command window settings including window size, compatibility, etc. The LCD monitor supports resolutions up to 1600x1200. Changing the windows resolution has on effect on dos mode display. I tried to create a dos 6.22 boot cd, but I failed. I got the 6.22 bootdisk from …

Changing the font size gets the display a little larger. Changing the screen resolution has no effect. The behavior is the same regardless of how I launch the program. I can't get the program to display in even half the screen when in full-screen mode. I think the issue here is mainly due to the new …

Do you mean the version of "dos" that comes with XP Pro? That works, except for the display - the program is supposed to run full screen. It only fills about 1/4 of the height of the screen, the remainder is blank. That is why I'm here. DOSBox solves the display problem - but then introduces the " …

The program and its data files require 250MB. I created a 300MB ram disk, copied in the program and data. I start DOSBox and mount the ram disk. It matters not whether the mount parameters say I have 4GB (the max I can get) or 8MB - the program still complains. Bottom line - I'm pretty sure that …

Well, this makes no sense to me. Tried it anyway. Problem remains. Jay

Attached a screen shot - upper window is a regular command prompt showing 499 GB free, lower window is DOSBox - you can see the mount command and the dir showing 4 GB free.

That's very strange... I'm also checking free disk space with dir.

chkdsk reports 4096 bytes per allocation unit (cluster) (512 x 8)?, 122096000 total clusters on disk, 121859301 clusters available. So I tried -size 512,8,122096000,121859301 (ignoring the readme which specifies a max value of 65534 for the last two parameters) with no luck. It's now reporting about …

You could be right - the error message may be misleading. No way to know for sure. The last version of this program was written against W95. The company folded and the software is unsupported... I searched the drive for any companion error files that may be related - but no luck.

I just tried - unfortunately it did not help. It still shows just 4GB free (4,261,217,792 to be precise). I'll try to figure out the exact parameters for my drive and try again. Thanks, Jay

XP Pro / SP2 DOSBox 0.72 E6850@3GHz CPU 2GB RAM 500GB free disk space Problem: I'm testing an old office management program (based on DataFLEX) - it complains and exits when it thinks there is less than 4GB free disk space available. Is there a way around this? There is actually 500 GB free on the …
