AX = 1110h
ES:BP -> user table
CX = count of patterns to store
DX = character offset into map 2 block
BL = block to load in map 2
BH = number of bytes per character pattern
Return: nothing
Notes: This function will cause a mode set, completely resetting
the video environment, but without clearing the video buffer
This function is designed to be called immediately after a mode set,
it is equivalent to AX=110xh except that:
Page 0 must be active.
Bytes/character is recalculated.
Max character rows is recalculated.
CRT buffer length is recalculated.
CRTC registers are reprogrammed as follows:
R09 = bytes/char-1 ; max scan line (mode 7 only)
R0A = bytes/char-2 ; cursor start
R0B = 0 ; cursor end
R12 = ((rows+1)*(bytes/char))-1 ; vertical display end
R14 = bytes/char ; underline loc
(*** BUG: should be 1 less ***)
the current block specifiers may be determined with INT 10/AH=1Bh,
looking at offsets 2Bh and 2Ch of the returned data (VGAVideo Graphics Array(Video Graphics Array) The video adapter introduced with the IBMInternational Busiuness Machines PS/2IBM PS/2, any model series of computers. only)
