In fact the chipset could address four sides with a max of 64MB per side.
The board you mentioned (which just happens to come up first if I put 'Intel
XZ' into Google) had three slots so that you could utilise more than just 2
x 128 to get to 256. You could use 1 x 128 and 2 x 64 if the 64s were
single-sided or 3 x 64 if that's what you had.

Yes. Addressing is really by, using the old terminology, "bank" (new
terminology being "rank") so "memory slots" is not entirely accurate. It's
usually the case that "memory slots" allow 'double sided' sticks, which
means two ranks, one on each 'side' (although the physical location is
irrelevant) in the one 'slot'.

The ZX can handle 4 ranks. That would be two 'normal' slots of double sided
RAM but it's allowable to distribute the 4 ranks among more than 2 slots as
long as everything adds to 4 ranks.

That adds some flexibility while adding confusion (if one assumes each slot
can take double sided sticks).

I'm not entirely sure about the 64 Meg per rank. That was the 'official'
number when the BX and ZX chipsets were made because that was the state of
the art in memory modules at the time but the BX can actually take 128 Meg
(of 'standard' density) per rank for the afore mentioned 768meg total in
three slots. It would seem likely that the same case applies to the ZX but
I haven't checked to know for sure.
