- Bummer... just be thankful that your BIOS looked first (some BIOS
- may have just checked for memory on the m'board.
-
- This is sorta weird... can you manipulate the video buffer or was it
- just put there as a convenience to dump the buffer during a capture.

- You mean your chipset on the m'board? If so, yes it probably does
- not allow holes to be mapped out... even if it did, you would not
- be able to use the memory since most operating systems are hard to
- configure to not fall in to the hole.
