DOS ain't dead - 64bit DOS sample

64bit DOS sample (Announce)

Hello,

based on a sample supplied by sinsi + T. Grysztar in the Fasm forum I made a simple DOS 64bit sample. It's a "normal" DOS MZ exe which should be able to run on any DOS on a 64bit-capable machine. If no such machine is available, Qemu64 will do as well.

The user interface is simple: when the program starts, it switches to long-mode and waits for keys. Keys it knows are 'r', which dumps some registers, and ESC, which makes the program switch back to real-mode.

It's written in assembly, in Masm - or more exactly: in JWasm - syntax. To assemble it a 64bit aware version of JWasm is needed ( the "experimental" version )
