Jazzz Posted May 2, 2006 Share Posted May 2, 2006 I've just upgraded my motherboard to MSI RS482M-IL, which is AMD 3100+ and has ATI Radeon XPRESS 200 / ATI SB400 -- north/south bridges. Now when I attempt to install from DVD I get the following error repeating on boot: USB Notification: The device "EHCI Root Hub Simulation" @ 0x53000000 has caused an overcurrent condition. The hub it is attached to has been disabled Still waiting for root device I tried booting both 10.4.6 and 10.4.5 DVDs, and from both VGA and DVI. BTW, This mobo runs XP very nicely, and video is Powercolor Radeon X700 PCI-E displaying on a 1680x1050 LCD. (Before upgrading, I had a DFI VIA board with AGP GeForce FX5500 and was running OSX at 1680x1050 happily with nVidia drivers, but without CI/QE.) The video card choice is based on my slim case (half height). On a side note, I may want to run OSx86 in VMware instead of natively, because I'm likely to use XP more often. However, I do plan to try VirtueDesktops (EDIT: Oops! I meant Parallels), which if it runs XP as-good-as-natively, then I'll be groovy. So, should I expect much poorer performance thru VMware, or just lack of video accelleration? (I'll give OSX it's own hard drive). TIA!

Virtue Desktop is not a hardware emulation app, it's only a manager for your desktop - it creates more than one virtual desktops and allow you to switch between them. It's more like you would have multiple displays.

U.C. Posted May 2, 2006 Share Posted May 2, 2006 Dood thats Paralells ur talkin bout. Its there on macupdate.com It seems one of ur USB devices is causing a proble. Install OSX with barebones config, then after booting succesfully, install other hardware. OSX being UNIX based doesnot depend too much on HW Configs like Windows.

Jazzz Posted May 2, 2006 Author Share Posted May 2, 2006 Thanks Unstable -- Parallel's is what I had in mind. Re: USB devices -- I have none attached. But it's a new system board, so I suppose it's possible there's a hardware fault. But it's more likely something about the chipset (??). I'll try disabling USB stuff in the BIOS. Update: Still can't install. Damnit! I had better luck with the DFI K8M800 & nVidia-AGP! I found a document that references "overcurrent condition" -- Intel® I/O Controller Hub 6 (ICH6), and other pages/posts that mention problems solved by clearing ESCD nvram. Alas, so far nothing has helped. Sheesh.

Jazzz Posted May 3, 2006 Author Share Posted May 3, 2006 Okay, that's it. I'm outta here. I tried VMware, but all I got was a "b0 error" -- even after setting up the disk with an AF partition, unformatted -- and I tried both PATA and SATA disks. I tried various methods of cdrom (Daemon Tools, native, no autoplay, etc.), but eventually VMware came up with an "exception has occurred -- unrecoverable error..." yaddy yadda. Booted a util CD and set the partition active, installed an MBR.... etc. Same. I had thought that changing mobo's to one that supports PCI-E (thus wider range of half height cards) and RADEON would give me a better chance of CI/QE, but it's just led me to spend another $200 and waste upteen hours... Screw it. After all, iTunes does run on Winblows.
