SYMPTOMS
========
The following STOP error message appears on your Windows NT Server:
STOP: 0x0000007F (0x0000000F, 0x00000000, 0x00000000, 0x00000000)
This problem only occurs on single-processor systems with the Intel Pentium Pro
processor.
RESOLUTION
==========
Disable the local Advanced Program Interrupt Controller (APIC) in the BIOS. Not
all vendors have implemented enabling and disabling of the local APIC as a BIOS
option. If this is the case, contact the system vendor and request an updated
BIOS that corrects Pentium Pro erratum 5AP and 6AP.
NOTE: Not every 7F - F fault in a Pentium Pro single processor system is
necessarily traceable to the APIC.
MORE INFORMATION
