vga_reset: reset video graphic board
NAMEvga_reset - reset video graphic board
DESCRIPTIONCall real mode c000:0003, which should be the video card's initialization routine. Should work in some cases when mode3 fails to restore text mode.
BUGSUsing this program is unsafe, and might (depending on the bios) result in a video card in a state that requires a hard reset to restore to normal, or even a hung computer.
