SIL 680 IDE PCI card not recognized

I recently purchased a PCI IDE/RAID controller card that uses the SIL 680
chip. I am not interested in the RAID feature and I intend to use it
with an older Tyan P3 motherboard which currently will not work with IDE
drives larger than 30 GB.

I tried running preliminary tests with it in a different motherboard
first and it was not being recognized by the BIOS or by Linux. So I tried
two other motherboards and got the same thing.

I was expecting the card to be reported by the BIOS during boot but there
is no sign of it. Later I tried booting into Linux 2.6.15 Kernel and
then doing "modprobe siimage" and the module installed, however no
messages were logged and I see no sign of the card or the drive anywhere
in /proc. 'lsmod' reports [permanent] and I can not do a 'rmmod'.

The card was advertised as being supported by Linux, however information
that was included with the card makes no mention of Linux .. only various
flavors of Windows.. but this is common with lots of cards and I never
had problems in the past.

Should the BIOS be reporting SOMETHING about the presence of the card?
All other cards I have ever used (sound, TV, scsi, network, etc..) were
always reported by the BIOS during boot and Linux picked them up with
no problems.

I tried disabling the on-board IDE controller and in all cases it made
no difference .. other than I could no longer get into Linux .. of course.

Does the "modprobe siimage" need parameters? I was looking around
for info on this but many places implied that everything should be
detected automatically, so I have held off going any further in that
direction for now.

I am beginning to suspect I may have a defective card.

I hesitate to try it in a Windows system since I did not purchase it
for use with Windows that and don't want to risk messing up Windows.

Have you checked that the necessary support & configuration exists in your kernel? You might need to recompile to get it configured properly based on what I just read on a very cursory search of google. is another thread with a tiny bit more info..

If the card is not shown in the output of 'lspci', then it is in fact dead.
