question about a BIOS setting

hey guys -- i was browsing through the BIOS yesterday trying to solve another problem when i came upon the option that says "OS select for DRAM:" the choices are "non-OS2" or "OS2"

just wondering what the difference is and what i should have this set on.

i'm running XP SP2 with 2gbs of corsair memory. any advice would be appreciated. thanks!
 
Actually, the question is not quite as cut and dry as it seems.
The typ reply is that you are not running old IBM O/S, so leave it "non" - default.
However, OS/2 has been "updated" to various Warp versions to the current latest ecomstation

with which you can dual boot.
The next point is that is often mentioned is since you are not running O/S2 or variant, it really doesnt matter what you set it to in bios.
However, NON OS/2 means using an O/S2 install with LESS than 64MB of RAM which is, of course, no one today. If you try to install old O/S2 on mobo with 512MB ram and set non O/S2 in bios, it may take all morning.
In other words, one can install OS/2 with either non OS/2 or OS/2 depending on your amount of ram relative to 64MB. Note that when O/S2 came out 64MB RAM was a bunch.
Further complicating things is that this setting does seem to effect XP also, since many overclockers report higher FSB capabilities with OS/2 "ON". The O/S2 bios setting is all about RAM handling.
And very strange setting it is - lol

Edit: I forgot to say - I always leave it "on" or "OS2" or >64MB for old mobo.


 
Bozo, thanks for the more complete answer. I never knew that.

But then again, I didn't know there was no 2 minute warning in college football either.
