VMWARE 32bit OS - Ram Limitation


Couple of questions.  I know the limitation to RAM for 32bit OS max of 4gig. However.

Q - If VISTA Ultimate 32bit is running say 8gig of ram, will my VMWARE PC's be able to use some of my 8 gig ?  I.E. = Base OS = Vista Ultimate only using the max  4 gig, however can I allocate the other 4 gig to my VMWARE machine(s)?

Q2 - At present I am using VMWARE Workstation, if the above is not possilbe in this version, which version would be suited.  The same applies to my base OS.

Many thanks.

Even though the BIOS would recognize 8 GB, the OS could only recognize 3.5 GB (even though System Properties shows 4 GB).

This is 32-Bit's inherent limitation.

Your VMware Guest would not see 4 GB since VMware Workstation uses a hosted environment scenario by depending on the Host OS for Resources.

The best option would be to upgrade your Host OS to Windows Vista 64-Bit and fully utilize the 8 GB RAM.

What about WIndows Server 2003 / 2008 32 bit OS.  I here of places that have this with 8 - 16gb of RAM but running 32bit OS Server 2003 / 2008 ???

Is there a version of VMWARE which will utilize BIOS RAM and ignore the HOSTED OS resources / ram?

You can check out ESXi which is a free download. - https://www.vmware.com/tryvmware/?p=esxi

This does not require any base OS to be installed
