Hi, I am looking into building a personal workstation around the Tyan S2915 or the Tyan S2927 for LinuxBIOS hacking.
I have been following the mailing list since January when Yinghai Lu posted a huge patch with support for the Tyan S2912, among other boards.
From Tyan's webpage it seems that the S2927, like the S2912, uses the
nVIDIA MCP55 southbridge. However, the Super I/O chip on the S2927 is a SMSC SCH5017 and not the Winbond W83627HF found on the S2912. The S2915 uses the nVIDIA NFP3600 + NPF3050 as the southbridge and the SMSC 5307 Super I/O controller.
Would Yinghai's patch support either of these two boards?
Thanks, Arvind

The SuperI/O would have to be coded for, but after that should be fairly easy. You'd also have some board-specific coding to do, too. Why not just get an S2912? Too easy?
The S2915 uses the nVIDIA NFP3600 + NPF3050 as the southbridge and the SMSC 5307 Super I/O controller.
Afaik, that wouldn't work with Yinghai's patch.

Are you sure? The website says "nVIDIA NFP3600". Is that the same as MCP55?

Afaik, that's not the same by any means.

for S2915, you need to refer to nvidia l1_2pvv with mcp55+io55.
and need to find out datasheet for SMSC 5307.

Hi,
I've had success with Tyan S2865 which uses SMSC DME1737 Superio, and I think SCH5017 is the same except for enhanced fan control, the data brief for it mentions "two and three piece linear fan function options".
I don't see an SMSC 5307 on their website, can you find any datasheets? (or "data briefs", as they call the fake ones for marketing the chips with NDA'd datasheets.) The 5307 might be the same as far as the serial port goes, and that's 99% of what LinuxBIOS uses on the Superio, AFAIK. (there might be board-specific uses of the GPIOs but at least you'd get serial output to start with)
I think SMSC LPC bus superio chips all have the same PNP programming interface, and the serial ports are probably at the same Device Index. The only board-specific part is the pin strapping to select PNP index/data register base address of 0x2e or 0x4e.
With the sensors-detect script in lm-sensors SVN I was able to see that the DME1737 on S2865 was at 0x4e. (A patch for DME1737 support was added Mar 24, which was after the 2.10.3 release, so you might need to use latest from their subversion repository for now)
Even if sensors-detect doesn't know about your superio, it should say the manufacturer, device id and the address, the address is really the important part. (since you can usually tell the Mfr from visual inspection)
If anyone has a board with an SCH5017 or other SMSC Superio, maybe they can try latest sensors-detect, and post results here and/or to lm-sensors.org? It would help with lm-sensors support, hardware watchdog support, and LinuxBIOS support to have that info.
Regards,
Jeremy
