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 (VGA only)

(see AH=1Bh,#00040)

INT 10 - VIDEO - Realtek RTVGA - SET USER GRAPHICS CHARACTERS

AX = 1110h

ES:BP -> user table

CX = bytes per character

BL = row specifier

00h user set

DL = number of rows

01h 14 rows

02h 25 rows

03h 43 rows

Return: nothing

Note: this function is meant to be called immediately after a mode set;

results are unpredictable at other times

INT 10 - VIDEO - TEXT-MODE CHARGEN - LOAD ROM MONOCHROME PATTERNS (PS,EGA,VGA)

AX = 1111h

BL = block to load

Return: nothing

Notes: (see AX=1110h)

the "monochrome" patters are 8x14 pixels in size
