How to UN mount a DOSbox drive


I am running DOSbox on a CentOS 7 machine. While setting things up I mounted a DOS "drive" letter to the wrong mount point. Short of stopping and restarting DOSbox...

How do I UNmount a drive in DOSbox?

I have searched and found 476 examples of how to MOUNT everything from a Windoze folder to the kitchen sink. No one seems to know how to unmount a drive.

TIA,

Ken

Thanks michaelk! I overlooked the -u option. I am using DOSbox for exactly ONE old FoxPro for DOS application which I wrote back in the early 1980's. I have been running it in dosemu on CentOS 6 since 2010. dosemu does not seem to work on CentOS 7 so I moved to DOSbox. I have my application running automatically from the DOSbox config file - [autoexec] section. I will probably never touch it again - until I upgrade to CentOS 8

Thanks again,

Ken

I still run a few old DOS programs and they work well enough using dosbox.

My ONE DOS and only program is a little expense tracker I wrote in FoxPro for DOS. Originally it was intended to track sales tax - which used to be an income tax deduction. I got tired of going though a box of receipts at tax time to add up the sales tax I had paid through the year. With my little application I recorded it throughout the year and simply ran a report at tax time. I think this worked for one year - then the tax law was changed and sales tax was no longer deductible Still I continued to enter my expenditures - less sales tax.

In 2005 my company offered and early retirement scheme. While my eligible co-workers ran around like a bunch of headless chickens trying to figure out if they could afford to retire, I simply ran some analysis against my 20 years of expense data and confirmed that I could go. And I did

My historical data is also handy to find out when I purchased something - like the washing machine which conked out. I had paid about $250 US for it 14 years earlier. Not worth repairing.

I have a very old home control system based on the Motorola 6801 from 1980s that needs DOS to compile and upload its control program. I use my laptop runs W10/linux and so the need for dosbox.

I was once going to build such a thing based on the Commodore VIC-20. Never did. I was also going to add a module to allow me to learn to program in assembler. Never did that either.
