SIS M760 Bios patch request for Amilo 1645 Laptop
Posted: Wed Apr 30, 2008 8:02 pm
Hello
I have got a Siemens Amilo A1645 Laptop with one of these horrible SiS M760 VGA Chipsets. It does 1280x800 on its lcd alright but no bios update or driver was able to make it use two screens at once correctly. ive got the univga3 driver installed and the vbios version 2.23.B2.
When i plug my TFT screen into the analog video out it isnt capable of running 1280x800 on its LCD (seems stuck at 1024x768) and the attached external screen is also only displaying 1024x768. Higher resolutions only lead to some kind of mouse activated border-scrolling function.
My Questions:
- Is there a way to patch my bios to use other resolutions on external screens?
- Or is there a way to update my video bios which is stuck at 2.23.B2 (the regular bios update didnt affect this)?
I would be grateful for any help offered
the bios im using (1.05c) is availible as an EXE file under
http://support.fujitsu-siemens.de/Downl ... LO%20A1645
(check the box, then click download)
other, strange versions (iso, disk image) under
http://support.fujitsu-siemens.de/Downl ... adID=50570
(choose windows xp)
im sorry that there isnt a direct link to post. i can upload one of these bios files to a direct location if someone tells me which version to take for this.
