these are nearly implementation instructions - I wasn't aware of this
call. you could have posted it the first time.
unfortunately AFAICS RBIL intermixed DH and DL here (it has an
advantage to be proud owner of MSDOS :)
changes needed:
hdr\pcb.h, 691
unsigned ASMPASCAL intr(int nr, iregs * rp);
INTR.ASM, 136:
no_read_error:
ret
+ global INTR
+INTR:
+ INTR
segment INIT_TEXT
;
DSK.C, 231
if (i == blk_dev.dh_name[0])
{
put_string("Error in the DJ mechanism!\n"); /* should not happen! */
}
else
{
+ /* according to RBIL (te 22 jul 04) */
+ iregs r;
+
+ r.a.x = 0x4a00;
+ r.c.x = 0x0000;
+ r.d.b.l = pddt->ddt_logdriveno;
+ r.d.b.h = pddt2->ddt_logdriveno;
+
+ intr(0x2f,&r);
+
+ if (r.c.x == 0xffff)
+ {
+ /* someone else makes a nice dialog */
+ }
+ else
+ {
template_string[DRIVE_POS] = 'A' + pddt2->ddt_logdriveno;
put_string(template_string);
put_string("Insert");
template_string[DRIVE_POS] = 'A' + pddt->ddt_logdriveno;
put_string(template_string + 6);
put_string("Press the any key to continue ... \n");
fl_readkey();
+ }
