avoid race condition that could corrupt user stack if DOS re-entered too soon 
apply suggested fix from SF bug 215 (https://sourceforge.net/p/freedos/bugs/215/), InDOS cleared but small chance DOS re-entered before user stack restored thus corrupting user stack

enable installation check for driver.sys 
For now we still only support subfunction 3 (return drive table) and subfunction 0 (check if installed) which we say yes.  This allows DOS Internals DRVINFO.EXE to correctly use internal drive table (it checks if installed and doesn't bother if not) and return corresponding information.  Note: subfunction 3 is still handled in int2f.asm for now, but may be moved to cleaner (but bigger and slower) implementation in inthndlr.c

E. C. Masloch f7947771cb config: only overwrite skip config prompt if it was displayed 
This allows to boot with SWITCHES=/F without any lone CRs.
 2024-08-05 20:45:16 -04:00
E. C. Masloch 314c8b627b do not display any lone Carriage Returns 
In combination with SWITCHES=/N in fdconfig.sys this commit makes
it so only proper CR LF linebreaks are displayed, for instance when
piping dosemu2 output to a file.

SWITCHES=/F will set SkipConfigSeconds so that config.c SkipLine will
display a string reading "\r%79s\r" to delete the prompt that it has
displayed. This overwriting should not be needed for SkipConfigSeconds=0
however. Refer to subsequent commit.

E. C. Masloch 8e8fcd1628 sys: fix, work on DOS versions that clobber di in int 25h/26h 
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.
