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. Cliff Heyer cliffhanger@cup.portal.com
