Chris, I had a look at your motherboard features. It mentions PCI 2.2 in the BIOS Features section of the document at http://www.supermicro.com/products/motherboard/P4/845/P4SGE.cfm Unless BIOS selectable, this should differ from a PCI 2.3 compliant bus. This could possibly explain the problems you are facing with the SI3052 chip initialization within the Intel's binary code (537core.lib) part of the 537 driver. -- sip:Vouters.Philippe@xxxxxxxxx IM: philvout (Yahoo!) http://vouters.dyndns.org/ Philippe Vouters (Fontainebleau/France) -------- Message initial -------- De: Chris Tracy <chris.t.tracy@xxxxxxxxx> À: Philippe Vouters <Philippe.Vouters@xxxxxxxxxxx> Cc: Antonio Olivares <olivares14031@xxxxxxxxx>, Bjorn Wielens <Uniacke1@xxxxxxxx>, discuss@xxxxxxxxxxxxx, Marvin Stodolsky <marvin.stodolsky@xxxxxxxxx> Sujet: Re: Intel 537EP - driver loads but cannot use modem Date: Mon, 8 Mar 2010 11:51:35 -0500 Hi Philippe, Thank you for taking a look at this problem! As far as I can tell, I cannot configure PCI clock speeds in the BIOS of this particular machine. I have had issues with HD capture cards in PCI-X slots, which needed similar treatment, and have seen some motherboards that allow you to tweak this even on a per-slot basis. However, I did take a look at the motherboard manual... My SuperMicro 5013G-M 1U server contains a SuperMicro P4SGE motherboard. The motherboard manual states: Expansion Slots: Five 32-bit, 33 MHz PCI slots (P4SGR/P4SGE) BIOS: APM 1.2, DMI 2.3, PCI 2.2, ACPI 1.0, Plug and Play (PnP) So, it does not look like my system is PCI 2.3 compliant, but all of the slots should already be running at 33 MHz. I believe that I am already running the latest BIOS rev available for my system, so maybe my only option is to try another system which is known to be PCI 2.3 compliant...? I did notice in the manual that I have a "Resource Controller By" BIOS option which is currently set to "Auto <ESCD>". This appears to be the way to turn PnP on/off on my system. I haven't tried switching to "Manual" yet... I will wait to see what others think about the "537EPG" markings that Bjorn asked about. :-) Thanks! -Chris On Mar 7, 2010, at 4:51 PM, Philippe Vouters wrote: > > Dear Chris, > > With my ASRock motherboard, the AGP/PCI clock speed is selectable under > the BIOS.
