<DIV>Dear Peng, </DIV>
<DIV></DIV>
<DIV>Yes, indeed, Lenovo X200 and X301 laptops have Core 2 Duo processors</DIV>
<DIV>which support 64-bit operation. From Linux you can determine this</DIV>
<DIV>using /proc/cpuinfo (look for 'lm', for 'long mode'). </DIV>
<DIV></DIV>
<DIV>Booting a Barrelfish image on such machines is exactly the same as on</DIV>
<DIV>a regular desktop. </DIV>

<DIV>> Hi,</DIV>
<DIV>> I have downloaded Barrelfish source code, and noticed a detail in</DIV>
<DIV>> the README file, saying:</DIV>
<DIV>> The biggest compatibility problems are likely to be in the PCI/ACPI</DIV>

<DIV>> * Intel x5000XVN</DIV>

<DIV>> * Lenovo X200 and X301 laptops</DIV>
<DIV>> I wondered can the last item "Lenovo laptops" be used as your testing</DIV>

<DIV>> your 64-bit code on them?</DIV>
<DIV>> My problem is I have only such laptops rather than high-perfomance</DIV>

<DIV>> Thanks in advance.</DIV>
