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
Faulty hardware was determined to be the cause of this error. The problem
was reported to Intel.
