Hallo Eric,
does FreeDOS already support int 2f.122f, set DOS version number?
Now it does - see patch below ;-)
We already had a similar function on another API (int 21 somewhere), but using int 2f.122f would be DOS 4+ compatible and nice for a SETVER...
See the updated CVSPATCH.TXT and KERNEL.SYS at http://linux.tu-varna.acad.bg/~lig/freedos/kernel/
Regards, Lucho
P.S. I'm not responsible for damages to the following patch caused by my e-mail client, Opera! For the real patch, see CVSPATCH.TXT. Needless to say that it's for the unstable (DANGEROUS :) branch.
