- Quick answer #1: if you are planning to do all your development under
- Windows, just ignore the issue.
-
- Quick answer #2: if you will be using a C compiler other than MSC version
- 7, just ignore the issue.
-
- Somewhat longer answer:
-
- Version 7 of the Microsoft C compiler requires a DPMI (DOS Protected Mode
- Interface) memory manager to execute. It requires the interface defined
- by DPMI version 0.9, plus the nonstandard MS extensions to that spec.
-
- [An aside: ain't standards wonderful, especially when ignored?]
-
- A DOS application running under Windows 3.1 is provided with the necessary
- DPMI interface by Windows itself and nothing needs to be done to DOS.
-
- If you are running a barefoot DOS application which requires DPMI you must
- have previously modified your system to include a DPMI server. Since
- DOS does not include a built-in DPMI server, the MSC version 7 package
- includes a full retail copy of Qualitas' memory manager 386-to-the-Max.
- 386^max is a replacement for HIMEM which provides all of its functions,
- plus those of emm386, as well as providing the necessary DPMI services.
-
- 386^max will run on all '386 systems (the documented minimum chip for MSC7)
- as well as many '286 machines. There is a variant of 386^max called Blue Max
- which includes code to squeeze a little more memory out of IBM PS/2
- adapter BIOS address space, but 386^max will work on a PS/2.
-
- Last time I looked the Qualitas product was claimed to be the only
- commercial memory manager which offered the necessary DPMI interfaces.
- QEMM and others will probably become capable of doing this in the
- future (if they haven't already done so).
-
- The only difference I know of between the 386^max package in the MSC7
- box and what you can buy from a retail store is that the copy you
- get with MSC7 includes a coupon you can send back to Qualitas to
- get a copy of Blue Max (replacing the 386^max in the C7 box). Cost
- of the upgrade is US$20 plus US$25 for shipping outside of continental
- US.
-
- You may be able to get the upgrade and/or additional info from the
- European office of Qualitas. The Rolodex card in my kit shows:
