- You machine is powerful enough to run OS/2. And yes, you really need 8 MB
- to use OS/2 graphically, which is the usual way to use.
-
- >megs soon. I OS/2 worth trying? I run Windows 3.1 now in enhanced mode.
- >Will it be slower or faster? Does OS/2 support 1024x768 at 256 colors yet?
-
- I suggest that you wait util OS/2 2.1 GA version, which will include Win3.1
- enhanced mode support. The current WinOS2 (Win emulation under OS/2) in OS/2
- 2.0 is based on Win3.0 code and is naturally slower than Win3.1. Sometimes,
- a Win app runs faster under OS/2 than under a real Windows, indeed, because
- it can benefit from faster HPFS file system. But in general, you cannot
- expect that considering the much more powerful multitasking capability of OS/2.
- What I mean is that under OS/2, apps share the CPU and other resources and
- they are running concurrently. On the other hand, under Windows, you get
- basically task-switching, and only one app is running at a time essentially,
- which has grabbed all the system power and resources. If you run a Win app
- seamlessly, the lunch of it will be slower, because OS/2 needs to lunch a
- vitual DOS machine first, and then WinOS2, and finally the app itself. When
- it is running, you can usually get 80-95% speed (sometimes even faster) than
- under a real Windows. This is my feeling and experience.
-
- >Can I use the HPFS and still run my windows apps? Thanks for any help..
-
- Yes, you can run most DOS and Windoze apps with HPFS, which is transparent
- for them under OS/2. Sometimes you could experience installation failure
- since OS/2 reserves some filenames locked which might happen to be the
- installation program needs to process. For example, Mathcad 3.1 for Windows,
- it copies DIR0/1/2/3, etc., compressed files into separate directory and then
- unpacks them. No problem with DIR1/2/3, but DIR0* are reserved by OS/2 to
- process store files recovered by CHKDSK. I had to installed the thing under
- real DOS on another machine, backup the installed directory, and finally
- restored into my own OS/2 and HPFS only machine. Some other DOS/Windoze apps
- use low lever disk access method to decompress their installed compressed
- files, which will also fail in the installation on a HPFS drive. The solution
- is the same as said above.
-
- OS/2 2.1 will be out in about three months. You are welcome to this very
- powerful environment. I whole heartedly recommend it to you.
