QEmu: Could not allocate physical memory

[q6z4k]

Hi!
For about a month I'm learning assembly on Linux. I allways wated to create a very simple OS.
All I have done is a simple bootloader that displays message in Real Mode.

I installed QEmu, but I face some problems with it! I downloaded FreeDos from http://www.oszoo.org/download.html, just to test how to run it with QEmu. After I un-compress it, and try to run it, I get error: Could not allocate physical memory

I try to run it like this:

qemu -kernel freedos.dsk

What did I do wrong? Do I need some bootloader? Thank you!

Yes, I know this problem, this message is showing when you have enough phisical memory in the system(linux), you must close some programs and try again:)
