  1. Acer 6930g need help

    Please see http://www.projectosx.com/forum/index.php?...ost&p=14655
  2. Fixed: http://www.projectosx.com/forum/index.php?showtopic=2118
  3. Anyone running Acer Aspire 7730G should take a look at here. Might work for other Acers too, maybe even for other laptops?
  4. As it seems I'm still too new user, I'm forced to write about this issue here Well, hopefully some DSDT experts drop by! I own a Acer Aspire 7730G laptop (pm45/ich9m, nvidia 9600m GT), on which Snow Leopard runs quite well. Graphics work, sounds too, usb without problems and even built-in usb webcam. However, something rather essential doesn't: other PCI express ports than those related to the GFX and sounds don't get memory and io ranges assigned to them. Because of this for example the ExpressCard slot doesn't work and plugging a card results in a kernel panic. I have been trying to find the problem in the DSDT by comparing it to other files and by taking a look at the ACPI specs. Unfortunately, this hasn't been too fruitful, as most of the changes I have tried to do are more copy&paste than understanding the real mechanics behind the DSDT code. So, to sum it up: I'm only looking at how to get io&mem address ranges assigned to PCIe bridges. USB works, GFX works, sound works -- but with this I need help. I have attached the DSDT.dsl in this post, as well as lspci information from both linux and osx. DSDT.dsl.txt lspci_linux.log.txt lspci_osx.log.txt
  5. AnVAL (ACPI Loader)

    Hello! I would like to know if this bootloader might be a solution to a larger ACPI problem I'm having. It seems that my laptop ACPI bios is badly written software, and it gives conflicting/bad addresses to pci bridges. Due to this some of the integrated hardware (lan, wlan) won't work and plugging an expresscard leads to kernel panic. Now, having read "ACPI" in the name of this project, I was hopeful that it'd be possible for me to take the addresses of the pci devices which work in linux and then with those override the bad ACPI default addresses... But yeah, it's almost 5 AM here and I might just be a bit too optimistic Thanks for all information you can give!
  6. I'm also having this problem. It seems to be common to at least Acer Aspire 7730G, Acer Aspire 7730ZG, and Acer Aspire 5739G. As far as I have understood correctly, the ACPI BIOS of these computers is a bit messy -- which is the problem. While Windows and Linux are capable of dismissing the bad addresses given by ACPI and assigning new ones themselves, but OSX and BSDs don't have that. I guess we'd need to get somebody competent write us this missing functionality in to the IOPCIFamily.kext or into the bootloader. The probably most comprehensive thread on this issue can be found here: http://www.projectosx.com/forum/index.php?showtopic=694
  7. Hello everyone! I'm running Snow Leopard 10.6.4 on a Acer Aspire 7730G and almost everything is working rather smoothly. There is, however, one problem. I'm using this computer for video editing, and for that I need firewire connection (which doesn't exist in this laptop built-in). For this use I bought a DeLock firewire expresscard. In Linux the card works well through PCI hotplug and shows up in lspci -v as following: 02:00.0 PCI bridge: Texas Instruments XIO2000(A)/XIO2200(A) PCI Express-to-PCI Bridge (rev 03) (prog-if 00 [Normal decode]) Physical Slot: 1 Flags: bus master, fast devsel, latency 0 Bus: primary=02, secondary=03, subordinate=03, sec-latency=0 Memory behind bridge: c0000000-c00fffff Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable- Count=1/16 Maskable- 64bit+ Capabilities: [80] Subsystem: Device 5678:1234 Capabilities: [90] Express PCI/PCI-X Bridge, MSI 00 Capabilities: [100] Advanced Error Reporting Kernel modules: shpchp 03:00.0 FireWire (IEEE 1394): Texas Instruments XIO2200(A) IEEE-1394a-2000 Controller (PHY/Link) (rev 01) (prog-if 10 [OHCI]) Subsystem: Device 5678:1234 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at c0004000 (32-bit, non-prefetchable) [size=2K] Memory at c0000000 (32-bit, non-prefetchable) [size=16K] Capabilities: [44] Power Management version 2 Kernel driver in use: firewire_ohci Kernel modules: firewire-ohci OSX, however, doesn't seem to like this card. Plugging it in or booting with it plugged in results in a kernel panic with mentions of "AppleUSBUHCI : start unable to initialize UIM" and IOPCIFamily(2.6) Now, I'd really much like to find out whether this problem has something to do with the Texas Instruments chip or whether this is related to the chipset of this computer (ICH9) -- and if possible, get it fixed. If it is related to this DeLock built card not being supported by Snow Leopard I can of course go and buy more expensive FW 800 -card which I'll be needing, but I'd rather not do that if the problem is with the ExpressCard and pci hotplugging. Any ideas out there? I can upload a photo of the kernel panic.
