Unless of course your board manufacturer changes the rules via its own
implementation.  My Mylex board (with DX) can be configured as 1,2,4, or 8 Mb
using 256K, 256K, 1Mb, 1Mb, simms respectively.  No other combinations are
allowed - no I haven't checked to see if others are really possible, as there
seemed no reason for Mylex to "hide" other combinations (they don't sell
RAM).  Facts are helpful, but implementations tell the whole story.

Yup.
