SiS 735 chipset

SiS 735 chipset

[Mordechai Ovits]

Does anyone know if the SiS 735's features, such as IDE, USB, Ethernet and 
sound are supported by Linux?

Thanks,
Mordy

Hi,
I've just bought a ECS K7S5A motherboard with this chipset on, and it seems 
to work pretty well so far.  The sound doesn't seem to be supported at 
the moment, but the IDE, USB, and Ethernet(*) seem to be.  I've had a few
'status=0x58' errors when doing some heavy disk activity, but apparently
this can be solved by a kernel option ('use multimode by default') which
I'm about to try (note: these errors only occur when using UDMA as far as I
can tell).  If that doesn't fix it I'll put a question to this list...
The AGP can also be made to work by using 'agp_try_unsupported=1' as a
module/kernel argument.  I'm currently updated the PCI.IDS file and the known
AGP chipset list to include the 735, but I'm checking that the AGP works
fully first.

Cheers,
Adrian.

(*) I can't test the Ethernet properly, but doing 'insmod sis900' works ok,
and the status info it comes back with as it initialises looks reasonable.
Any more than that, I can't verify.

Hi,
I've attached the patch that lets the kernel SIS AGP driver recognise the 735
chipset as it seems fine.  I don't know of any system for testing the AGP
support so I tried QuakeIII and that ran fine.  The patch is against 2.4.8-ac4
but since all it changes is a couple of (infrequently) changed tables it should
work fine on later versions.  I've CC'd Jeff Hartmann with it as he seems to
be the maintainer of the AGP side (but isn't listed in the MAINTAINERS file).

Cheers,
Adrian.

Well that was a good start, I was /sure/ I attached the patch this morning.
Ok, attempt no.2, apologies to anyone that wanted it...

Cheers,
Adrian.
