$A000:0000 or (flat) $000A0000, yes.
well, there's OR AL,AL (followed by JZ or JNZ) and JCXZ.
JCXZ is only one instruction, i.e the fastest, but there's
no JCXNZ instruction unfortunatly.
So OR reg,reg is the shortest way with NZ option.
Otherwise, JCXZ is the fastest, OR and CMP equal speed.
I think.
Isn't there some sort of windows echo? Think so...

Ahh ok.  I looked through a few other programs that I had the source to, and
they were doing this, but I couldn't exactly figure out how/why!
Ok, now, function 4a expects ES to point to the segment of the block of

Quite so.
It is? What is MS-DOS 7 then, err.. I mean "Win95" :)
OK, then one final question on this: in protected mode, you will define a
selector, set the limit, etc, and load a segreg with that selector; then you
get the base address of that selector from the descriptor table, and when you
return to real mode, load that base address (shifted right 4 bits to turn it
into a real mode segment) into the segreg.. would that be correct?

assistant: Replying to a message of James Vahn to Darryl Gregorash:
I agree this is a big problem for folx who do not understand the Intel
architecture; I do personally think, however, that little-endian processors
are more "natural" than big-endian ones, since the lowest order bits of any
object, no matter what size, are stored in lower order bits in memory.
I think I still prefer the "right-to-left" description. In fact, if we were
to think of bits in memory in the Intel architecture as beginning at the
bottom right of a "page", and read them off right to left, bottom to top,
then all this confusion would disappear forever.. because then the higher
order elements of any data object _would_ appear on the "page" in the same
order as we write them.
As I said before, it is only when we insist on ordering some things left to
right/top to bottom, but other things right to left, that the confusion
arises.

Actually, IBM outsourced virtually all of its hardware components, initially
to one outside contractor for each component.
They ran into problems when the AT was released, because the contractor for
the hard drives couldn't deliver on time.. they ran a hurried contract
through someone else, and then that contractor and IBM suffered because there
were defects that could not be addressed in time for release. After that, IBM
insisted on having two outside sources for any hardware item before they
would release a new machine.
