subject: Dual Drives = 2 OS`?

It's 01 Jul 97  07:44:02,
We'll return to Jonathan de Boyne Pollard and Aaron Gelner's
discussion of Dual Drives = 2 OS'?
 JdBP> MEM is a DOS program.  It reports the configuration of the Virtual DOS
 JdBP> Machine that it is run in.  In OS/2, you can have multiple Virtual DOS
 JdBP> Machines, all running side by side.  One of the many advantages of
 JdBP> OS/2 is that each VDM can be individually configured, using the [DOS
 JdBP> Settings] dialogue that is accessible from the [Settings] page of the
 JdBP> VDM program object's property notebook.
 JdBP> The XMS and EMS memory configurations reported to DOS programs are
 JdBP> complete fictions.  Unlike on DOS, they do not represent the actual
 JdBP> physical memory configuration of the machine.  So one of the things
 JdBP> that you are going to have to get used to is that your DOS tools,
 JdBP> however convincing their output may be, really _aren't_ reporting the
 JdBP> state of the actual physical hardware to you when they are run on
 JdBP> OS/2.
This extends to other hardware.  Fire up a DOS diagnostic on this box,
and it'll tell you that you have 3 serial ports, all with 16550 UARTS.
Open the case, you'll find just two, one occupied by a mouse.  Where did
the extras come from?  I'm using SIO and Vmodem to create a couple of
telnet ports. :)
Of course, OS/2 diagnostics report a truer picture of the system. :-)
... Life?  Sure,I've got a life.  ->  C:\Life\*.*
