-   alpha=2 is the primitive element of GF(2**m)
-   HARI's COMMENT: (4/13/94) alpha_to[] can be used as follows:
-        Let @ represent the primitive element commonly called "alpha" that
-   is the root of the primitive polynomial p(x). Then in GF(2^m), for any
-   0 <= i <= 2^m-2,
-        @^i = a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
-   where the binary vector (a(0),a(1),a(2),...,a(m-1)) is the representation
-   of the integer "alpha_to[i]" with a(0) being the LSB and a(m-1) the MSB. Thus for
-   example the polynomial representation of @^5 would be given by the binary
-   representation of the integer "alpha_to[5]".
-                   Similarly, index_of[] can be used as follows:
-        As above, let @ represent the primitive element of GF(2^m) that is
-   the root of the primitive polynomial p(x). In order to find the power
-   of @ (alpha) that has the polynomial representation
-        a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
-   we consider the integer "i" whose binary representation with a(0) being LSB
-   and a(m-1) MSB is (a(0),a(1),...,a(m-1)) and locate the entry
-   "index_of[i]". Now, @^index_of[i] is that element whose polynomial
-    representation is (a(0),a(1),a(2),...,a(m-1)).
-   NOTE:
-        The element alpha_to[2^m-1] = 0 always signifying that the
-   representation of "@^infinity" = 0 is (0,0,0,...,0).
-        Similarly, the element index_of[0] = A0 always signifying
-   that the power of alpha which has the polynomial representation
-   (0,0,...,0) is "infinity".

-/* DOC_PASSIVE_PROBE:
-   In order to ensure that the BIOS checksum is correct at boot time, and
-   hence that the onboard BIOS extension gets executed, the DiskOnChip
-   goes into reset mode when it is read sequentially: all registers
-   return 0xff until the chip is woken up again by writing to the
-   DOCControl register.
-   Unfortunately, this means that the probe for the DiskOnChip is unsafe,
-   because one of the first things it does is write to where it thinks
-   the DOCControl register should be - which may well be shared memory
-   for another device. I've had machines which lock up when this is
-   attempted. Hence the possibility to do a passive probe, which will fail
-   to detect a chip in reset mode, but is at least guaranteed not to lock
-   the machine.
-   If you have this problem, uncomment the following line:
-#define DOC_PASSIVE_PROBE
