<RANTMODE>
I'M HIGHLY DISAPPOINTED TO FIND THAT SOME FORMERLY
WORKING CODE DOESN'T WORK ANYMORE;
I'M IN PARTICULAR DISAPPOINTED AS
THIS CODE WAS ONLY CHANGED TO SAVE SOME 20 BYTE OF
INIT CODE. WELL - THIS SAVES 20 BYTE, BUT COSTED
ME A MONTH TO DISCOVER - AND AN ADDITIONAL HOUR TO FIX.
TO ALL OPTIMIZERS: HANDS OFF. GO PLAY SOMEWHERE ELSE.

UWORD GetBiosKey(int timeout)
{
iregs r;
ULONG startTime = GetBiosTime();
if (timeout >= 0) do

init_call_intr(0x16, &r);
- if ((unsigned)(GetBiosTime() - startTime) >= timeout * 18u)
+ if ((unsigned)(GetBiosTime() - startTime) > timeout * 18u)
return 0xffff;
}
while (r.flags & FLG_ZERO);
/* key available or blocking wait (timeout < 0): fetch it */
r.a.x = 0x0000;
init_call_intr(0x16, &r);
return r.a.x;
}
