That's a pity.
But to be sure that we are talking about the same file: The video bios file I
am
talking about is "mtg_3240.dat" (3240 stands for the build number). It is
included in a zip file in the windows driver installation file.
This zip file's name is "vbios852-855.zip" (i855 is my chip set).

I knew that. However, my hope was that the other files included in this
"vbios*.zip" file are part of the OEM utility program BMP which is used to
modify certain parameters in the original bios, according to the description
in

http://www.versalogic.com/Support/Downloads/pdf/69030bg.pdf

(The chip set described in this pdf is totally unrelated to my problem, but I
thougth there might be a connection between the BMP utility program and the
com_bmp.exe included in the zip file mentioned above.)
I hoped that the other files in this "vbios*.zip" file are the necessary
modifications for the implementation of a 1400x1050 video mode.

Which laptop are you using?
I will bear this warnings in my mind. Anyway, I want to try the bios
replacement.
Would something like this work:

su
dd if=bios_replacement_file bs=1 count=65536 of=/dev/mem skip=49151
(49151 = 0xc000 - 1)

??

Thanks for your help.
