bit VMware picture on the 32




Indeed, operating a 64-bit Microsoft Exchange Server 2010 over a 32-bit processor in VMware is achievable.





I have an old Intel Core two Duo with Windows XP Specialist 2002 operating on it, MCSA Windows Server 2008 that i acquired it to work.





First of all, see in case your CPU is capable of running a 64-bit OS. Look for 'Processor check for 64-bit compatibility' within the VMware web site. Operate the plan.





If it claims your processor is capable, restart your computer and go into the BIOS and find out when you've got 'Virtualization' and therefore are able to enable it. I had been in a position to and received Windows Server 2008 R2 running under VMware on this old laptop computer.





I honestly question it, for any number of motives, however the most significant a single is the fact that you can find some instructions which might be allowed in 32-bit mode, but not in 64-bit mode. Particularly, the REX prefix that is used to encode some instructions and registers in 64-bit mode is a byte in the type 0x4f:0x40, but in 32 little bit style the identical byte is both INC or DEC with a fastened operand.





Due to this, any 64-bit instruction that is prefixed by REX will be interpreted as either INC or DEC, and won't give the VMM the chance to emulate the 64-bit instruction (as an example by signaling an undefined opcode exception).





The one way it may be carried out would be to make use of a entice exception to return to the VMM soon after every and every single instruction to ensure that it could see if it desires special 64-bit handling. I simply SharePoint 2010 Administration not see that taking place.
