Yes. This is much more precise:
XP 32 Bit - 4GB minus whatever the BIOS gives to hardware
XP 64 Bit - 128GB minus whatever the BIOS gives to hardware
Vista 32 Bit - 4GB minus whatever the BIOS gives to hardware
Vista 64 Bit Basic - 8GB minus whatever the BIOS gives to hardware
Vista 64 bit Premium - 16GB minus whatever the BIOS gives to hardware
Vista 64 bit Business, Enterprise, and Ultimate - 128GB minus whatever the BIOS gives to hardware
If the hardware imposes physical memory decoding limits that are less than the OS limit, then for all OS it is:
- hardware memory limit minus whatever the BIOS gives to hardware
Actually any 64 bit OS should be able to use a heck of allot more RAM then 128G.
Should but won't because Microsoft hard-limits the kernel even in 64-bit OS for product segmentation (i.e. marketing) reasons.
