Date: Sat, 24 Jan 2004 14:49:58 +0100 From: Stephane Marchesin Subject: Re: [SDL] 3DNow! detection on a P4 system Well... I found another bug : 3dnow was detected on P2/P3 cpus. So I took one more look at the code and found a mistake in CPU_getCPUIDFeaturesExt : The condition for having extended cpuinfo is that when we query extended cpuinfo we get a result >= 0x80000001. So we must exit if eax < 0x80000001. The attached patch does that.
