johnny1234boy Posted June 25, 2010 Share Posted June 25, 2010 Hi I am trying to get dual video cards working with Snow Leopard 10.6.4. Here is my setup Gigabyte GA-EP45T0USB3P Core2Duo E6500 (OC to 3.85 Ghz) Geforce 9400 GT Geforce 8400 GS I've used Kakewalk 2.2 installer for GA-EP45-UD3R (closest to my board) which installs the Chameleon 2.0 RC4. These are extra KEXTs that I am running fakesmc.kext JMicronATA.kext VoodooHDA.kext (and removed AppleHDA.kext. Otherwise kernel panic at boot) ---------------------------------------------- OK, so here is where I am now. Fresh 10.6.0 will not even boot with the second video cards in the PEG2 position. However, once I've updated to 10.6.3 (and .4 later) it will boot with the card in place, and it somewhat shows the info under the "More Info" (see the attached image). It lists both cards, but the VRAM info on the second card (8400 GS) is wrong. I've been trying to update DSDT.aml file to get the cards working but no joy so far. I've followed this thread kdawg's http://www.insanelymac.com/forum/index.php...83349&st=20, and particularly kdawg's code for updating the DSDT. Below is the newly added part to my table file to compile the DSDT file. Device (PCI0) { //test compile Device (PEG1) //<--GeForce 9400 { Name (_ADR, 0x00010000) //<-- Important!

johnny1234boy Posted June 26, 2010 Author Share Posted June 26, 2010 OK, I got it to not kernel panic with the below code. However, the triple monitors via dual video cards is still not working. Can someone take a look at the code below and provide feedback? Device (PCI0) { Device (PEG1) { //<-- Geforce 9400 GT Name (_ADR, 0x00010000) Name (_PRW, Package (0x02){0x09,0x05}) Device (GFX1) { Name (_ADR, Zero) Name (_PRW, Package (0x02){0x09,0x05}) // <--Test to fix static Name (_SUN, 0x0B) Method (_DSM, 4, NotSerialized) { Store (Package (0x16) { "@0,compatible" ,Buffer (0x0B){"NVDA,NVMac"}, "@0,device_type",Buffer (0x08){"display"}, "@0,name" ,Buffer (0x0F){"NVDA,Display-A"}, "@1,compatible" ,Buffer (0x0B){"NVDA,NVMac"}, "@1,device_type",Buffer (0x08){"display"}, "@1,name" ,Buffer (0x0F){"NVDA,Display-B"}, "NVCAP" ,Buffer (0x18){0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x03, 0x00, 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0a, 0x00, 0x00, 0x00, 0x00}, "VRAM,totalsize",Buffer (0x04){0x00, 0x00, 0x00, 0x40}, "device_type" ,Buffer (0x0D){"NVDA,GeForce"}, "model" ,Buffer (0x17){"NVIDIA Geforce 9400 GT"}, "rom-revision" ,Buffer (0x06){"3173a"} }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } } Device (PEG2) { //<-- GeForce 8400 GS Name (_ADR, 0x00060000) Name (_PRW, Package (0x02){0x09,0x05}) Device (GFX2) { Name (_ADR, Zero) Name (_PRW, Package (0x02){0x09,0x05}) // <--Test to fix static Name (_SUN, 0x0C) Method (_DSM, 4, NotSerialized) { Store (Package (0x16) { "@0,compatible" ,Buffer (0x0B){"NVDA,NVMac"}, "@0,device_type",Buffer (0x08){"display"}, "@0,name" ,Buffer (0x0F){"NVDA,Display-A"}, "@1,compatible" ,Buffer (0x0B){"NVDA,NVMac"}, "@1,device_type",Buffer (0x08){"display"}, "@1,name" ,Buffer (0x0F){"NVDA,Display-B"}, "NVCAP" ,Buffer (0x18){0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x03, 0x00, 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0a, 0x00, 0x00, 0x00, 0x00}, "VRAM,totalsize",Buffer (0x04){0x00, 0x00, 0x00, 0x20}, "device_type" ,Buffer (0x0D){"NVDA,GeForce"}, "model" ,Buffer (0x17){"NVIDIA Geforce 8400 GS"}, "rom-revision" ,Buffer (0x06){"3169a"} }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } } Name (_HID, EisaId ("PNP0A03")) a couple things I've learned Create a USB flash drive to boot the DSDT.aml file from, so when you screw up you can recover quickly Hmmm, you actually have to keep the filename DSDT.aml in upper case!. DSDTSE tool spits them out in lower case dsdt.aml DSDTSE tool seems to be very flaky with hidden characters that confuses the compiler. I ended up using BBEDIT and iASL Link to comment https://www.insanelymac.com/forum/topic/222752-help-with-dual-video-cards/#findComment-1499257 Share on other sites More sharing options...
