Hello,

first, i'm from Germany. My english isn't so good. Man kann mir aber auch gerne auf deutsch antworten.

I have a MSI MK3M-V (MS-7061) with VIA/S3 UniChrome IGP.
Because i want to connect the VGA directly to the SCART of a PAL-TV i had to change the Resolution, Refreshrate and had to select interlaced for the IGP.

PowerStrip for Windows is a Programm, that allow all this settings. But the Motherboard BIOS with VGA-ROM does not Support the Resolution.

I need 720X576 Pixel @25Hz/50Hz interlaced

VIA also didn't support free Resolution. With many other Card's and Driver's does it work with PowerStrip.

I updated the VGA-Rom in the BIOS from KMCRT_09.ROM to KMCRT_13.ROM. But nothing changed.

Can someone help me with my Problem and fix the BIOS to apply other Resolutions. Best where free scale. Or 720X576.
And the RAMDAC/Pixel Clock have to set some MHz (around 5) lower then yet.
And i have to enable interlaced.


Many Thx to all how want to help.

PS: I can't use another Grafikcard for the PC. There is no more Space in the Case. It's a HTPC.

The ROM can be downloaded here: http://216.158.218.35/edoc/bios_uploads/7061v32.zip

Unfortunately, you can't add resolutions that the Video Chip itself was not designed to display. :(

The VideoChip is desinged to display this and other resolutions.
It's also desinged to show interlaced. That what i need too.

With the Opensource Unichrome-Driver for Linux every Resolutions is possible.

I looked around many hours in on many Sites to get this Information. It's only a Problem about the BIOS and the Windowsdriver.

Virtually every video chip is designed to display every resolution (limited by ramdac and available memory ofcourse). and yes, it is a windows issue. tell VIA to write a driver or include every resolution in the vga bios (i doubt that there's enough space ;)) or go for an OS that supports modelines.

This is what I meant (@what cp said).

Since I could not find a "white paper" on this setup explicitly defining the hardware, I chose to word my response in a general manner.

Thanks.

the solution still is:

a) tell VIA to write a proper driver
b) use an OS that supports drivers with (virtually) free resolution

i can for sure tell you that b) is not available with Microsoft Windows.
If you email me include [WIMSBIOS] in the subject.
