Does anyone know a way to check a BIOS int 16h
to see if it can handle the extended keyboard?

Some XT BIOSes crash if you try a Fcn 10h on
them .

I thought the BIOS was written so that if
an interrupt contains an invalid function code
the BIOS does nothing and returns. But in this
case it seems to crash.....I thought I could
try a 10h and if it returned nothing I could
try a 00h standard XT read.

Please mail & I'll post,
Cliff
