  Hello,

 As I found, I have overlooked a routine updating bios 0x6c & 0x70
fields.
It is in function video_update (module tty.c):
                                                                               
        *(u_long *)&BIOSDATA[0x6c] += 1;    /* Timer ticks since
midnight... */
        while (*(u_long *)&BIOSDATA[0x6c] >= 24*60*6*182)
{                    
                *(u_long *)&BIOSDATA[0x6c] -=
24*60*6*182;                     
                BIOSDATA[0x70]++;                   /* BIOSDATA[0x70] #
times p>
        }                      

The problem with this code is that it works only "if (!booting)". I do
not see the reason for such a restriction. I would suggest to move it to
int08 routine in timer.c in replacement to what is suggested in my
previous message, since this this routine also increments field 0x70.

  Thanks,
   Igor.
