   Hello,


 I do not know were to put this...


 There is a problem with doscmd that comes with FreeBSD 4.0.
It seems like nobody updates BIOS time (BIOSDATA[0x6c]). It is
a BUG. This causes MultiEdit to hang under DOS 5.0. 

Adding the following code to timer.c corrects the problem:

static
void                                                                    
int08(regcontext_t
*REGS)                                                      
{

/* similar to what is done in bios.c) */

    struct timeval
tv;                                                         
    time_t
tv_sec;                                                             
    struct timezone
tz;                                                        
    struct tm
tm;                                                              
                                                                               
    gettimeofday(&tv,
&tz);                                                    
    tv_sec =
tv.tv_sec;                                                        
    tm =
*localtime(&tv_sec);                                                  
    *(u_long *)&BIOSDATA[0x6c]
=                                               
        (((tm.tm_hour * 60 + tm.tm_min) * 60) + tm.tm_sec) * 182 /
10;         

/* end */

   
softint(0x1c);                                                             
}
