I had time to work with freedos in virtualbox the last two days. I experienced some odd overheating problems. The Macbook Pro I used was getting hot at the bottom and shut down automatically.
It seems that FreeDOS grabs all the CPU power it finds. The Activity Monitor (Applications - Utilities) show CPU Usage of 100 or 102 %. The solution I found: For normal work at the DOS terminal (prompt only) the problem is solved by having a line LH FDAPM APMDOS in AUTOEXEC.BAT. (Another program people recommend is DOSIDLE, but it is unfree and doesn't seem to work better than FDAPM.) With this trick CPU usage goes down from 100% to 4%. But as soon as programs like edit, nc or nc clones (doszip) or other foreground or background applications are started (ftpsrv, sockets ftpd etc.) CPU usage goes up again to 100 %. This can be avoided by Virtualbox itself: In the processor settings for the virtual machine you can limit the CPU usage. I set a limit of 40 %. What does FreeDOS want with 40% of an i5 anyhow? Does anyone has more ideas about that problem? ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2dcopy2 _______________________________________________ Freedos-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-user
