Hi there,
I am trying to install Descent 2 via DOSBOX. I am receiving errors that I do not have enough drive space although there is plenty.
At the command prompt of DOSBOX, I TYPE: mount c g:\ -t cdrom. The install is located on a cd drive-G. I then go to c:\D2DATA and run the setup.
Setup runs fine until It asks me which drive it can install to. This is when the error about insufficent disk space comes up. I made a fresh partition
of 600mg bytes since old dos games don't like anything over 2gb, I believe. I tried installing on another drive and the same thing happened. The install
does not see my drives that are full.. Right now I'm at an impasse as what to do.
Any takers?

steve

You're doing it wrong. First you need to mount any folder on your real hard drive as C in Dosbox. This is where files will be copied. Then mount the physical CD as D.
For example:
mount c c:\dosgames
mount d g:\ -t cdrom

What you did was mount the CD drive as C, so Dosbox has no space to write to.
Also, you don't need to make partitions. Dosbox can use your hard drives directly no matter the size.

Not sure if the above advice helped the OP, but just in case, there's a command in DOSBox that defines the free space on a virtual drive (in megabytes) called freesize.

Some DOS-based installers check for free space on the HDD before copying any files, and by default DOSBox reports 100 MiB (I think), which might not be what the installer expects. I've found that having 600 MiB free size is usually good enough to work with any installer that I've come across:

1mount c C:\DOS\hdd1\ -freesize 600

Assuming that C:\DOS\hdd1 is where you put your DOS-related stuff.

Note that DOSBox will always report the specified figure as the amount of free space (in megabytes) on the mounted drive, no matter the actual size of what you already have there. So for example if I have installed a number of large games at C:\DOS\hdd1 with a cumulative size of 590 MiB, any installer that checks the amount of free space on the virtual C: drive will still recognize there are 600 MiB of free space available.
