Hi, Could somebody with experience tell me what is the minimum requirement (Hardware requirement) for running Unix/SCO with Open Desktop (X)? Right now I have: 386/387 @25Mhz, 32k cache 4 Megs Memory 120 Megs HD, IDE, 15ms ATI VGA-Wonder, 512K, Bios version: 1.3 Comp. Bios: Pheonix Monitor: NEC 3D (Brand: NEC PowerMate 386/25) With my actual configuration, will it work. I have heard that it requires a minimum of 6 megs mem. and 100 megs HD. Is it true? ************************************************************************* E-Mail: genius@bart.cs.mcgill.ca *************************************************************************

Is it true? \-- The Open Desktop Release Notes recommends a minimum of 6mb RAM and 100mb of disk space, like you mentioned. You can run in 4mb of RAM, but if you would like to make use of the X window system, I'd really recommend that you have at least 6mb, preferably 8mb. Remember, X binaries are pretty big, and after you've got the kernel loaded into memory (default ODT kernels tend to range in size from 2.8-3.2mb), you'll have very little room left for user processes. You can tune your kernel down, by removing unused drivers and tuning various parameters, but that only goes so far. Right now, I'm running on a 386/25 with a 387 installed and 8mb RAM. My kernel is ~2.2mb in size, which leaves me with ~5.5mb RAM for user processes. It's usually enough to keep the system from swapping, unless I run lots of X clients. The 100mb disk figure is for an installation that includes the Ingres DBMS system. If you don't intend to install or run Ingres, you'll save yourself about 24mb. Also, you're not likely to want all of the Unix OS packages. Of course, the Xsight distribution takes up quite a bit of space...and if you would like to do any sort of source code development in the future, you'll need lots more. If you plan on just running the runtime, especially if you don't intend to use Ingres, 80-100mb should be adequate.
