automatic enable of PAE in windows servers

hi,

i have read windows automatically enables pae if dep enabled on computer supports hardware-enabled dep, or if computer configured hot-add memory devices in memory ranges beyond 4 gb

i wanted ask how can check if system enables pae or not,

the same configured hot-add memory.

what i'm trying see here,  that if pae has been enabled automaticly.

( and if so, need disable (i familiar pae disabling part - bcdedit...))

*this question applies windows 2003 (32 bit), 2008 servers (32 bit)

thanks!

for pae regardless of 2003 or 2008 (32bit), focus on reading physicaladdressextension setting.  if set 1, pae kernel loaded when computer started.

for hot memory add, appears need work requirements backwards.

per http://msdn.microsoft.com/en-us/library/ms175490.aspx

hot add memory requires sql server enterprise , available 64-bit sql server, , 32-bit sql server when awe enabled. hot add memory not available 32-bit sql server when awe not enabled. hot add memory available windows server 2003, enterprise , datacenter editions. requires special hardware supported hardware vendor.

therefore, need determine following

1) 64 or 32 bit windows 2003/2008 enterprise or higher (standard / web editions fail)
2) sql enterprise (standard edition fail)
3) 32bit os sql awe enabled, meains pae must enabled well.  (pae disabled or awe disabled fail)
4) use hot add memory sql server 32-bit, must start sql server using -h option

if of above not match hot memory add not possible.  note: 64bit not use pae
