SYMPTOMS

When a Windows 98-based computer is placed into Standby mode and then resumed, the computer may stop responding (hang) if it contains an Integrated Drive Electronics (IDE) hard disk that is accessed using Direct Memory Access ([DMA], which is also known as Bus Mastering).

CAUSE

When it resumes, Windows 98 issues an incorrect wakeup command sequence to an IDE hard disk that uses DMA.

This problem has been reported to occur with the following portable computers running Windows 98:

  • IBM ThinkPad 770E
  • IBM ThinkPad 770ED
  • IBM ThinkPad 600
  • IBM ThinkPad 560D
  • IBM ThinkPad 380Z
