Wednesday means it's time for another Ask TUAW! For this edition we've got questions about what Macs will support Snow Leopard's forthcoming OpenCL acceleration, using Boot Camp with multiple partitions, connecting a Mac mini to HDMI, automatically importing images into iPhoto, and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.

The relationship between Apple and NVIDIA, the manufacturer of the graphics chips in most Macs for quite some time now, appears to be souring at an exponential rate. Electronista reports that negotiations between the two companies to continue their business relationship are not going well, with Apple accusing NVIDIA of being arrogant. According to a source with access to NVIDIA, Apple is on track to cut NVIDIA off as a graphics chip provider for the next 3-4 years.

If the two companies cannot reach an agreement, NVIDIA would continue to provide chips for models that currently use NVIDIA, but Apple would be likely to drop NVIDIA chipsets in updates to their product line, particularly in iMacs and MacBooks currently based on Intel's Nehalem architecture.

A significant factor in the disagreement is the way NVIDIA handled the graphics failures of MacBook Pros carrying the GeForce 8600M video chipset, which had a tendency to overheat and eventually stop working. Apple had to extend the warranty on MBP models graphics chips sold from June 2007 to October 2008 to three years (the Apple support page on this issue can be found here).

The relationship between Intel and NVIDIA hasn't exactly helped, either. Both businesses filed opposing lawsuits over NVIDIA's license to make mainboard chipsets with their own internal memory controllers. If Intel wins, NVIDIA could not make another chipset like its GeForce 9400M model that supports Core i7 processors, and would oust NVIDIA from Macs by exclusion.

Neither Apple nor NVIDIA have publicly spoken on the matter so far. Apple does have a history of severing relationships almost without warning, as they dropped ATI (now AMD) from Power Mac G4s after the company revealed Apple's plans ahead of a Macworld keynote address. However, if Apple does indeed drop NVIDIA, they may have to return to AMD in order to maintain their current graphics standard.

AppleInsider is reporting that the speculated refresh for the iMac and Mac minis lines might include NVIDIA graphics chips. This information was discovered while an InsanelyMac forum poster found some extension files included with the new MacBooks/MacBook Pros. The exentions were named, "iMac9,1" and "Macmini3,1."

Currently shipping iMacs and Mac minis have the model numbers of "iMac 8,1" and "Macmini2,1," respectively. The kernel extension .plist file is part of the SMC (System Management Controller) and ACPI (Advanced Configuration and Power Interface), and made reference to "CFG_MCP79."

The MCP79 is a graphcis chipset offered by NVIDIA that is found on the current line MacBook, MacBook Pro, and MacBook Air. For more information, you can read the forum posting at InsanelyMac.

Mac Pro users -- it's time to power up the graphics capability of your machine! ATI has announced the new Radeon HD 3870 Mac & PC Edition. Whether you're a serious gamer or a graphics designer, this new card features 256-bit 512MB GDDR4 frame buffer memory, 320 stream processors, twin dual-link DVI ports to run two 30" Apple Cinema HD displays, PCI Express 2.0 support, and more.

One of our readers pointed out that you can even use the HD 3870 in Windows running in Boot Camp on a Mac Pro. The Radeon HD 3870 runs in any Mac Pro and will be available in late June for a MSRP of $219.

Thanks to TJ & Seth for the tip!

Apple just released an update for iMacs sporting either a ATI Radeon HD 2600 Pro or a ATI Radeon HD 2400 XT graphics card. According to Apple, the update will "improve system stability" by installing a firmware upgrade on the graphics cards. This does affect the newly released iMacs.

After this update is installed, you should see ROM version: 113-B2250L-259. You can download the update by opening Software Update (Apple menu > Software Update) on the affected system, or by downloading the installer package directly from Apple.

Apple also notes: To complete the firmware update process, please follow the instructions in the updater application (/Applications/Utilities/iMac ATI Radeon HD Graphics Firmware Update.app). The updater will launch automatically when the Installer closes.
