hmm i'm still learning at&t syntax...but i tried:

asm("mov 0, %bx");
asm("mov bank, %dx");  //bank == bank number
asm("call *%0"
     :
     : "S" (pm_bank)   //the pm_bank() function i posted before
);
and still it doesn't work...BTW thankz for the real mode bank switching
info....i took out the multiply by 16..and now it works with UNIVBE which
i prefer....but the Pmode bank switching it still making me rip my hair
out =)....what i really need it source code that is identical to Sandman's
code (VBE.ZIP) but for VBE 2.0 Bank Switching... (or a new video card =)
)...but thankz for your help...
