Dunno about any of the other Unixen, but Solaris supports 32 bit mode on all platforms and also supports 64 bit mode on Ultras for 2.7 and later.

I know that NT4 doesn't have any 64 bit support and I believe that NT5 doesn't either.

jlevie: I believe Win2K has some sort of 64-bit memory support but I don't know the details. Fundamentally it's still a 32-bit OS, as you say.

Can I recommend doing a bit of internet 'legwork' yourself, and visiting the websites for each of the OS's you mentioned.

try:

www.sun.com for Solaris
www.compaq.com for Digital UNIX
www.unixsolutions.hp.com for HP-UX

You should be able to find most of what you are looking for on these sites, plus there are numerous unofficial sites which will fill in the blanks. Try searching for the product name in Yahoo.

I believe NT's 64 Bit support is in Windows 2000 Data Center Server, not yet released.  Hope your homework grade looks good.

Cool comment. That's what I sort of thought the question was about from the beginning...
