Changing the DOS font

NitroAtom

While looking through Ralph Browns interrupt list I found interrupts for obtaining pointers to the DOS font characters, one of the memory loactaions was F000FA6Eh for the 8x8 set, but these memory locations only contain charaters 00h-7Fh. I found that interrupts 1Fh, 43h, and 44h claim to be associated with characters 80h-FFh but the documentation says nothing about what to do with these interrupts.
I did notice that interrupt 43h said "This is not a callable vector". Does each interrupt have a vector (like a memmory location) that somehow you can read from or obtain a pointer to?

You know ints do right??? for vector, look at mem location (int# * 4) for rmode segment & (int# * 4) + 2 for offset.. i think, dunno try it!?!

well mail me or reply.

You were right about about the memory locations:
(int * 4) for segment
(int * 4) + 2 for offset
