Dave Johnson 5.27.2004 I am working on a small OS that has a modified mach kernal that runs the top layer of functional hardware. (my english no good.) My home brew os hot swaps kernal code from what i like to call a non-emu emulayer. if i want to run a unix prog and then a win32 prog the #1 kernal...

I try to be good at accepting critisism (spelling?), so feel free to critique any work
that I submit and any idea I present. I am all about trying to do what it takes to make
this all work.

Dee Sharpe 4.30.2004 Currently I am in the process of trying to load Warp 4 onto a Compaq Presario 1200TA laptop. Not really going too well, because of driver issues for the video chip & LCD and the PCMCIA & eithernet. As soon as I get this resolved, I will try to install OpenWatcom and see...

Yuri Prokushev 4.29.2004 I'm talking not about dos support at all. dos isn't primary goal. But still lot of CPI (At least VIO/MOU/MON and some DOS) still 16bit only. If we want not just another OS, but OS/2 clone then we need binary compatability. So we need to support 16bit calls. According kernel...

Dee Sharpe 4.28.2004 Yuri, you've got a point. The dos compatibility should not be too difficult, there are plenty of open source dos clones that could be modified. The problem would be rewritting the win16 portions. However, this rewrite could be in our favor; a chance to get windows compatibility...

2Dee Sharpe Well, having 16bit is required. At least if we want to have support
for 'old' OS/2 applications.

Dee Sharpe 4.25.2004

Which leads me back to another question. Is the goal here to recreate OS/2 Warp 4
with the 16bit portions as well? If so, then I think I will need to research the thunking
of 16bit addresses into 32bit addresses & vise versa...

I agree with Sergey, OS/2's internal structure is vastly different from NT's. So, an NT
clone's structure would be vastly different from an OS/2 clone's. Considering the fact
that they would be cloning systems designed with different design objectives.

Dee Sharpe 4.21.2004 NT now uses a sub-system to emulate some of os/2's behavior. For one thing, this is mostly based on the early versions of os/2, back when ms & ibm were getting along. It is emulating what os/2 was doing natively; internally it's converting os/2's way of doing things into th...

Internal structure.
