Hi Eduardo,
sorry; pressed the send key too early ;)

it simply works as advertised
it doesn't leave unused clutter loaded as TSR; the remaining ~15 K
seem to be necessary (even on second glance)
THANKS.
some minor comments:
void _fmemcpy_local( void far *dst, const void far *src, size_t num )
{
void far *d = dst;
const void far *s = src;
// fastest implementation so far
// using rep movsD
__asm {
push es;
push ds;
push si;
push di;
mov cx, num;
les di, d;
lds si, s;
//
push/pop strictly not necessary
// but
doing the byte moves at last
//
favors aligned buffers
shr cx,1;
pushf
shr cx,1;
rep movsd;
adc cx,cx;
rep movsw;
popf
adc cx,cx;
rep movsb;
pop di;
pop si;
pop ds;
pop es;
}
return;
}
void _fmemcpy_local( void far *dst, const void far *src, size_t num )
{
// it's ok, using
inlining but works only wordwise
_fmemcpy(dst, src, num);
return;
}
with inline optimization is also ok, but only works with words
is a bit faster; my pure read speed from disk goes up from 26 MB/sec
to 43 MB/sec. read speed from SSD is 50 MB/sec now ( I7 920 machine)
_fstrrchr_local() should check that it doesn't touch str[-1] if the
character isn't found
in REDIR.C
cli
mov ss, ax
mov sp, (offset newStack) + STACK_SIZE - 2
sti
CLI/STI is not necessary; from the 80386 programmers reference manual:
'a MOV into SS inhibits all interrupts until after the execution of
the next instruction (which is presumably a MOV into eSP)'
and VMWare will not run on 80286 or lower ;)
