Bug Report

CWSDPMI reports wrong CPU family for IA64/Intel P4/AMD K8

Summary:

DPMI API 0x0400 (Get Version) returns cpu family as 15 for recent CPUs.

Analysis:

CPUID is used to get the CPU family.  Instead of using all 4 bits to return
the value, recent CPUs return all ones in this field which indicates
an extended family field should be used.

Workarounds:

None.  I will mask with value 7 in future releases, which will return
all newer CPUs as cpu family 7.
