Subject: RE: REALTEK SVGA DRIVER

The realtek graphics driver by Mattolini Riccardo
<mattolin AT aguirre DOT ing DOT unifi DOT it> defines two 320x200x256 modes:

  - standard linear memory
  - ModeX like planed memory

There is no need for the ModeX like one, so it should be disabled.

Change the definition of req_hiX

req_hiX         equ    0        ; disable high resolution mode X support

and delete the following line:

	dw      320,    200,    256,    013h +  val_hiX ; Mode X like

This definition was taken from the stadvgax.asm (I guess) witch was for
test purposes only. The et4000x.asm uses 320x200x256X too since all other
256 color graphics are ModeX like and one could use a libgrx without
the linear 256 color routines in this case.
