DOS ain't dead

Hello,

I wonder if there is another packer can deal with DOS .SYS drivers, besides UPX.
I searched FreeDOS ML and there is a packer named sy2pack (or sy3pack) but can't find any on the web now.

Regards,
Roy

It can't compress PC-DOS 2000's EMM386.EXE.

EDIT: I can compress it with CMC/UPX/etc. by removing loadhi.vxd appended in the end of emm386.exe, and fixing EXE header.
but still, DOS hangs when running DEVICE=EMM386.EXE line.

EDIT2: finally found diet 1.45f can pack it and still runs with DEVICE= line.
