echo 1 > /proc/sys/abi/ldt16
I don't know if that will pass muster. A lot of people still use DOSEMU and even more, VirtualBox.

When they tried something similar before by disabling 16-bit segments, there was quite a bit of screaming, so they added:
Code:echo 1 > /proc/sys/abi/ldt16
I wonder what Linus thinks of the proposal--looks like he's not in favor of it.
These yoyos broke floppy support in x86 and then replied "who cares?". Someone needs an attitude adjustment.
A future version of Linux running VirtualBox running an old version of Linux running DOSEmu - no problem. The old Linux is in it's own sandbox and still has the VM86 code
Ah, thanks Mike for the explanation. I suppose someone could rewrite DOSEMU to simulate the switch to VM86 mode, but I suspect that won't happen. 16-bit DOS is purely the domain of fossils, it seems.
Christ, I remember when the Lunix zealots made it a point of pride to support any piece of hardware they could lay their grubby paws on the reference manual for.
