Yep.  It's video mode 13 hex.

The  IBM technical manual does exist.  I am not sure how "available" it is but
it does exist. I've looked at it briefly and there seems to be a few 
inconsistencies in the way they've described things.  For example, in
one place they describe mode 13h as "bit-plane" and in another place
they describe it as pixel-packed "memory-mapped"...sigh...
