If this is true, why does not the PHOENIX Technical Reference Series
"SYSTEM BIOS" book say so? On page 138 they suggest a method 
using int 16h Fcn 10h. Unfortunately, I find some XT BIOSs *crash* when
this Fcn is used.

The book lists the BIOS data area bit at 40:96 you mention,
but nowhere do they suggest if it can be used to determine the 
keyboard type.
