Hi Jeff Hartmann!
I have been looking at the agpgart module trying hard to make my new Laptop (Dell C400 with an intel i830M) work properly with X version 4.2.0. I saw you were listed as an author of this module, so I hope that you can help me out here.. if not I am sorry for bothering you! The main problem is that the amount of �Stolen memory� is forced by the Dell BIOS to be only 1MB, not enough for the 1024x768x16, and the amount of stolen memory cannot be modified by the user in the BIOS setup � the problem is specific for Dell C400, other computers with the i830M chip seem to work according to the XFree mailing lists. I have been playing with the XFree driver module, and it seems that even if you make the driver ignore the inadequate amount of stolen memory, the BIOS simply refuses to switch to the desired video mode in the final int10 call to change the video mode. The best solution would be if Dell released a BIOS upgrade,- this does not seem likely though. What I would like to ask you is, do you know of any way to alter the amount of stolen memory, for instance from the initialization inside the agpgart module ? See e.g. http://xfree86.org/pipermail/xpert/2001-December/014388.html which unfortunately does not work... What I mean is that since Windows is able to change to the desired video mode, it should be possible to persuade the BIOS post-boot. Thanks!!
