DOS doesn't crash like Windows.
GRR Martin uses Wordstar and MS-DOS to write his novels because he does not want to be distracted by pop up windows and system alerts and updates.
- yjftsjthsd-h 6y ago> DOS doesn't crash like Windows. No, it crashes like DOS. I suppose if your application is well written and you have fully exercised the functionality that you use, it might be more stable, but "reliable" is not a word I would have associated with those systems.
- jacobush 6y agoIt’s like embedded software. DOS is basically bug free at this point. If there are bugs in DOS, they are known. ANY bugs will be in the application.
- neverartful 6y agoOr misconfigured CONFIG.SYS.
- beagle3 6y agoOr some clash with a TSR (sidekick?)
- SomeoneFromCA 6y agoIf you a write a simple protected mode monitor and debug it well, your app (running under the abovementioned monitor) will be more stable than if it were running on Linux, Windows or other monstrosity.
- pjmlp 6y agoIndeed it doesn't crash, just hangs in some strange way that forces a reboot, or if you are lucky it affects the beeper that starts issuing random beep noises with different kinds of volume until you reach for the power button running like crazy,
- bonzini 6y agoYour application crashes. DOS does not.
- pjmlp 6y agoI guess you never wrote DOS applications, nor used it on its prime days.
- bonzini 6y agoI did; I mean that if the system crashes it's your application's fault, not DOS's.
- pjmlp 6y agoHow can you prove that?
- neverartful 6y agoI suspect that they're alluding to the fact that DOS was more of a program loader than an OS and that once it loaded your program it was your program that was in the driver's seat. BUT there are subtle issues with drivers and networking still.
- pjmlp 6y agoI know that, but unless you can 100% guarantee that the application was clean from any kind of DOS interrupt calls, there are zero guarantees that it wasn't DOS, one of the drivers or the pseudo multitasking TSRs that were the culprit, there is no way to assert that the application was the one at fault.
- secondcoming 6y agoI can't recall the last time I had a BSOD
- sgerenser 6y agoConsider yourself lucky. I had a spate of BSODs a couple months ago presumably after some combination of Windows 10 updates and Lenovo updates on my work-issued ThinkPad. Rolling back updates didn’t seem to help. Finally went away after some other update installed. After the 5th one in maybe 10 days I was ready to have the machine wiped and reimaged (if I didn’t smash it with a sledgehammer first).
