Og det tyder p? at det er Intel der ikke helt holder sig til "standarden", da Microsoft?s 64bit Windows Server 2003 er 100% kompatibel med AMD?2 64bit processorer. Det er Intel?s ikke!
Already some weeks ago we have in a detailed message described that the 64-Bit is obviously not 100 percent compatible extensions of the x86-Befehlssatzes of AMD and Intel, it thus fine differences - in the implementation anyway - in addition, in the result gives; and that, although AMD64 should be actually software-compatible alias x86-64 (presented in April 2003) and EM64T alias IA-32e (last Monday presented).
In the meantime Intel the 64-Bit Xeon with Nocona core presented (we reported) and there it around a workstation CPU acts, which together with a fire-new PCI express Main board to be sold is and with an operating system (Windows XP 64-Bit edition) works, which yet at all is not on the market, was the number of Reviews for introduction on the market naturally close zero. Only a few "Big Player" under the hardware magazines such as INQ have tried, a Review in time to the Launch to make - and encountered thereby numerous problems which were not to be solved so far.
One tried the 64-Bit Windows for the Opteron, which one can download free of charge as Preview at Microsoft, to bring on the Xeon Nocona to running. However the system already fell with the installation after the integration of the SCSI drivers. Searches at Microsoft resulted in that the Preview version was approved for the AMD Opteron and the Athlon 64, not however for the 64-Bit Intel Xeon.
After Microsoft is obviously not yet so far, the alternative lay close to test the Nocona with a 64-Bit Linux since the Opteron Launch in April 2003 is available already and meanwhile time had to mature. Since it had to go fast, one took the Knoppix version, which can be gebootet by CD. To all astonishment of the author however Knoppix refused the start with the message that the 64-Bit Long mode was not supported and one instead a 32-Bit distribution was to use.
