I'm sorry to ask you to bring me up to date wolfgang, but from your
recent questions, I'm feeling left behind lately ...  :-( LOL

> no clue how to alter Screen_Start_Address from PM32

By "Screen_Start_Address from PM32" do you mean Int 10/AX=4F07h?

RBIL seems to indicate a protected mode entry point for 4F07h can
be returned via Int 10/4F0Ah/BL=0.  "Function 7" here means 4F07h.

"02h	WORD	offset of protected-mode code for Function 7
(Set Disp Start)"
http://www.delorie.com/djgpp/doc/rbinter/it/87/0.html

That table is returned via Int 10/4F0Ah/BL=0

"INT 10 - VESA SuperVGA BIOS v2.0+ - GET PROTECTED-MODE INTERFACE"
http://www.delorie.com/djgpp/doc/rbinter/id/92/2.html

If that's not what you meant, then:

What is Screen_Start_Address for?  BIOS VGA? VESA? VBE?
How do you set it currently?  memory? register? BIOS call?

>question is about VESA mode 81ff and where to locate 2..16 GB.

Was that the question?  Where to locate more memory to save to?

> INT10 works only in RealMode and that's what I want to bypass.

Do you mean VBE2.0 or VBE3.0?
Or, do you need a specific Int 10h function?

Anything useful in PM32 BIOS?
Do you use $PnP, $PCI, $ACF or other BIOS32 Service Directory calls?
