INT 0F C - IRQ7 - PARALLEL PRINTER

Desc: this interrupt is generated by the LPT1 printer adapter when the

printer becomes ready

Notes: most printer adapters do not reliably generate this interrupt

the 8259 interrupt controller generates an interrupt corresponding to

IRQ7 when an error condition occurs

INT 10 C - CPU-generated (80286+) - COPROCESSOR ERROR

Desc: this interrupt is generated by the CPU when the -ERROR pin is asserted

by the coprocessor

Note: AT's and clones usually wire the coprocessor to use IRQ13, but not all

get it right

INT 10h - LIRVGA19 - CHAR HEIGHT HOOK

Desc: LIRVGA19.COM fixes display problems on some notebooks by hooking

INT 10h and resetting the BIOS character height (MEM 0040h:0085h)

to 10h on return, if it happens to be greater than 10h.

Program: LIRVGA19.COM is part of the Lithuanian LIR codepage support package

developed by LABAS u.a.b.

INT 10 - VIDEO - SET VIDEO MODE

AH = 00h

AL = desired video mode (see #00010)

Return: AL = video mode flag (Phoenix, AMI BIOS)

20h mode > 7

30h modes 0-5 and 7

3Fh mode 6

AL = CRT controller mode byte (Phoenix 386 BIOS v1.10)

Desc: specify the display mode for the currently active display adapter
