Hardware Drivers, Panicky Kernels

By John Rizzo  |  Posted 2005-05-06 Print this article Print

Tiger also has caused some incompatibility with driver-level software related to hardware. For example, the Radeon X800 XT graphics card from ATI Technologies Inc. has ROM software that is incompatible with Tiger.
The ROM software can cause a kernel panic, a type of crash when the Mac screen is covered with lines of code.
ATI recommends that Tiger users downgrade to the original version 104 of the ROM software. The installer for ATIs April ROM Update provides the ability to downgrade. "The next update addresses [these] issues and will be posted end of this month or early next month," said Carrie Maynard, ATI public relations manager for Workstation, Mac and Technical Marketing. Users can also see kernel panics when upgrading to Tiger with Maxtor FireWire and USB hard drives connected to the Mac. Maxtor recommends that users disconnect Maxtor external drives before running Apples Tiger installer. However, the company said it could not predict when a fix would be available. "We work with [Apple]," said a Maxtor spokesperson, "but we dont have an answer, as we dont test compatibility with OSes."
