I am currently writing a keyboard macro program in assembly (grunt, snort) and will have to discriminate between XT-type and AT-type keyboards (101 keys). Could somebody please answer the following questions: - Is there any way to check whether an AT-type keyboard is used in a certain configuration? - Is there any need to check this, or can you just always use INT16 AH=10h (Extended Keyboard Read) to read a key? Any help would greatly be appreciated, Michiel Huisjes. -- Michiel Huisjes. (huisjes@cs.vu.nl) ..!uunet!cs.vu.nl!huisjes

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
