Re-POSTing via int10. > (II) RADEON(0): Primary V_BIOS segment is: 0xc000 Can you please ask the gurus: What is the difference between POSTing with the X driver and POSTing with vbetool, if both versions use int10? And can I have the "better int10" of the X driver as an isolated piece of code so that resume will eventually work even if X is not running?
