There are now various laptops out there which use the Intel i830m and do not follow Intel's documentation aparently. These laptops lock-in the stolen memory to 1Mb or possibly even less, and do not allow the user to properly configure it in the CMOS settings. In these cases, it is a BIOS flaw, and Intel comments to that effect on the Intel developer site. In lieu of a BIOS update for such laptops, the only way to work around the issue is to have the video driver program the chipset directly. There was a patch floating around which claimed to fix this, however testing the patch resulted in a non working driver that did not solve the problems either. Intel has not yet released the i830 documentation to the public however to my knowledge, and so there's no way anyone can write a proper workaround. Does anyone have a contact at Intel who might be able to help out with this problem? -- Mike A. Harris Shipping/mailing address: OS Systems Engineer 190 Pittsburgh Ave., Sault Ste.
