# It is possible that the 390X and 600E already featured the newer 0.18 micron 400MHz Mobile Pentium II.
# It is not completely clear if the 770E and 770ED had Mobile Pentium II processors or desktop Pentium II processors at 266MHz.

Vitex: Optimalization flags

According to /proc/cpuinfo, my 770X has a desktop PII, as opposed to a mobile one.
# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 5
model name : Pentium II (Deschutes)
stepping : 2
cpu MHz : 297.817
cache size : 512 KB
Versus a 770z...
# cat 770z/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 6
model name : Mobile Pentium II
stepping : 10
cpu MHz : 364.038
cache size : 256 KB
Dunno if this info can be relied upon or not.

Interesting. The Specs say that the 770E/ED has non Mobile Pentium II (or at least one can interpret is like this), but that the 770X and 770Z have Mobile Pentium II. Interesting is the difference in the model number of the output you posted. I'll look into this again, when i have time. I found the specs quite confusing in this point and didn't believe that they used desktop processors. [[User:Wyrfel|Wyrfel]] 19:37, 20 Aug 2005 (CEST)

Is it OK ?
