We have been trying in the last few days to install PC Oracle on an IBM PS/2 Model 70 (DOS 4.0). The machine is configured with 3M of RAM, but the machine locks up during installation. After playing around a bit we were able to get a "Kernel Log" of the error - Error: Insufficient memory; 896K of extended memory required. We're wondering if anyone else has had this experience and could lend some advice. Oracle Corp. says there should be know problem, and would love to help for a price. The suspicion here is a bug in DOS 4.0. Steve Yoman Graduate Center/CUNY Bitnet: SMYGC@CUNYVM.Bitnet Internet: SMYGC@CUNYVM.CUNY.EDU

I would check to make sure that your 2+ MB of extended memory is in fact recognized by DOS. There are a number of utilities out there to check how much extended memory is available (plus the PS/2s are pretty friendly to configure). Make sure that you are defining extended memory, not expanded memory. The brute force method would be to try to create a 2 MB extended memory VDISK (use the /E switch) -- if that works, then your machine is probably behaving itself. Another thing to watch for is if you are using any 386 environments (DESQview, 386-to-the-Max, etc.). They use Virtual 8086 mode and can conflict with products which use 80286 protected mode like Oracle and Informix. A new convention for 386 DOS environments, called VCPI (Virtual Control Program Interface), should help to limit such problems in the future. (BTW, if there are any Informix protected-mode users out there affected by this, we have a patch that provides support for VCPI-compliant environments in the .06 products. The upcoming .06C versions include VCPI compliance as well.) Hope this helps. -- Alan S.
