I want it to be one of many possible options. <br>
The idea is that when you run a Open Gem program in ReactOS it will
look like a Windows program.&nbsp; I.E. The Open Gem part of the Dos
subsytem would translate the GEM GUI calls to Win32 or Win-NT API
calls, making it look like a windows program.<br>

    <span>I'm interested in starting to code the DOS
subsystem. <br>
    <br>
So I am going to list some possible design principles:
    <br>
    <br>
Avoid excessive switching from V86 mode and Protected mode.
    <br>
Limit direct access to system hardware by DOS programs (especially IO).
    <br>
Must differentiate CPU exceptions and Software interrupts.
    <br>
Each DOS process would have its own private first Megabyte of Memory. <br>
At least DPMI v. 0.9 support.
    <br>
Dos API support (Including Long File Name support.)
    <br>
    <br>
Possible design additions:
    <br>
Native handling of DJGPP DPMI programs (I.E. skip DJGPP stub-loader and
jump directly to the DJGPP COFF image).

GEM</a> GUI API Support.
    <br>
Bios and Video ROM virtualization.
    <br>
    <br>
Additions, subtractions, modifications, or comments anyone?</span>
