Hi,

I have a PCHIPS M570, which is based on the SiS 586 chipset. This M/B does
support ultra-DMA/33. 

I installed the Patch for IDE/ATAPI improvements, that was dated in October
'98. This did not explicitly support the SIS I/F, but did have support for the
Intel PIIX, PIIX3 and PIIX4 controllers and the CMD 0640, and Applo.

This version worked well, even though it did not "support" my PCI controller
directly. Here is an extract of dmesg of the relevant part, and a bonnie output:

As can be seen, the performance is good. ( I have seen slightly better at
times.)

I then saw the note on the port-i386 list dated 29/11/1998 stating that a new
patch was out that supported the SiS controller. I eagerly installed the patch
on a clean (virgin) sys source. Compiled a new kernel using my config.
Installed and reboot. Everything looked fine and the drever now reported a
Silicon Integrated System 5597/5598 IDE controller. I then ran "bonnie" again,
I noticed it took a little longer. The results showed why;

It can be seen now that the performance is now terriable! Eeek! Looks like some
timming settings are out. Can you help me? I know that this is "unsupported" by
the project, but I would like to help debug it. Mybe my chip set is wired
differently. Dmesg output follows. (BTW I forgot to configure the sound card in
this build, but I doubt that would have any effect).
