I am pleased to announce the release of Merkey's LinuxWare, an MS-DOS (or
DR-DOS) loader that allows you to compile a Linux kernel as an MS-DOS
Executable, boot and load Linux from MS-DOS (while DOS stays resident).
This in essence is exactly the same as old Legacy Netware, and in fact, I
wrote a linker that does what the old NetWare custom linker did when it
compiled the NetWare kernel and linked it as a DOS Application. Linux
just like it does normally, except you can quit Linux and exit back to DOS.
Now who in the hell would want this? Well, it's damn convenient to have
(or was at one time) a DOS loadable program.
One cool thing inside LinuxWare is the loader debugger which is able to
initialize the kallsyms tables BEFORE LINUX IS LOADED and allow you to
walk through early loader init of Linux (like where it loads the GDT for
the first time).
So there is a lot of cool, innovative (not boring) and powerful code
within, that can be used to make it easier to debug and develop linux.
This tool was designed by me (and used by me) to take Linux apart and
study it thoroughly, and to shore up a sagging (and now deceased) DR-DOS
I stopped using it after 2.6 so its only up to 2.4.18, and there is an
early MDB integrated with KDB.
BORLAND compiler was used to build the DOS side, but DJGPP would probably
still work. As part of a lawsuit settlement, this code and IP reverted
back to my ownsership, and since its dead as a doornail DOS, might as well
see if there's stuff in here folks might could salvage -- one man's trash,
another man's treasure ...
So why would someone as hated as you even want to work on Linux? A.
It's a free country. I have some good stuff that helps people, so why
the hell not. Who made you people god (with a small g) anyway?
So why are you acting like ...
This is a good question. At present, It only reserves 0-1MB for DOS and
the rest of the memory is available for Linux. It's whatever Linux
wants to use. One thing it does allow is Linux to call DOS interrupts
from protected mode and return.
I am in process of cleaning up the patch series and prepping it for
2.6.27. Give me a couple of weeks and I'll post a cleaner version of the
code with the loader debugger, and I'll submit it to Andrew's MM tree as
