SYMPTOMS

Your computer may stop responding (hang) during the boot process if the computer contains a processor that runs at 850 megahertz (MHz) or faster. When this occurs, the computer hangs before the Windows Millennium Edition (Me) bitmap is displayed. Computers with a Japanese BIOS may be more susceptible to this problem.

CAUSE

Windows attempts to estimate the computer's speed by reading the keyboard repeatedly for 55 milliseconds. However, the number of iterations may exceed 65,535 on computers with a very fast read character BIOS function and overflow the variable that holds the count. Windows then assigns a small value to a number that causes slower system handling.
