After going into protected mode no INT 10H can be used. If using VBE page selecting can not be done unless going back to real mode, right?
I traced the page-selecting program of BOCHS and got these:
out 0x01ce, 0x0005
out 0x01cf, page
out 0x01ce, 0x0005
in inval, 0x01cf
inval = page means succeed
So can I use these code in protected mode?

Some people said it necessary to go back to real mode while one wrote an article telling how to control VBE in p.m.
