Running on DR-DOS v7.03, the int 25h call zeroes di leading to a crash here when di is expected to preserve the stack pointer. So push di twice and pop it twice. The second pop always gets the saved sp, regardless of whether int 21h or int 25h/26h are used. Refer to https://github.com/SvarDOS/edrdos/issues/57#issuecomment-2119360035
fd kernel
FreeDOS kernel - current 0xFD version is 2.43 (2043)
The FreeDOS kernel implements the core MS/PC-DOS (R) compatible functions. It is derived from Pat Villani's DOS-C kernel and released under the GPL v2. Please see http://www.freedos.org/ for more details about the FreeDOS (TM) Project. This was originally a branch based on 2042 SVN 0xFD kernel; the full svn history has since been added to git (see other branches) and current development of release kernels are available here. Please fork and submit a Pull Request!
Compiled kernels ready to use (just copy kernel.sys over an existing install) are available at http://www.fdos.org/kernel/testing/git/ - also available are the source archive and fdpkg compatible packages. *** TODO update links/upload archives
This version of the kernel is intended only for 8086+ or 80386+ IBM compatible computers in continuation of the goals of the FreeDOS Project. Please see http://www.fdos.org/kernel for my 0xDC kernel that is work on merging back in some of the original portability aspects and other supported features at the cost of some compatibility with older hardware/software.
