No

V.2.4.6 - 2.4.1 unknown if earlier
1024 * 768 256 colour palette.
protected mode without paging.
Writing to the address in vbe ModeinfoBlock.PhysBasePtr
produces no changes on the screen. That is really bad.
I tested it on ca.10 physical pc's where this works.
I expect the bug has do to with nonpaged protected mode
where no virtual addresses exist but only logic and linear.
I can deliver boot image for this. please email.
