[comp.sys.mac.apps] HELP SOFT PC!

thewho@elaine22.stanford.edu (Derek Fong) (02/22/91)

After visiting a store and fooling around with SoftPC, I couldn't seem to get
a straight answer on how the "hard drives" work.  (yes, another clueless comp-
uter salesman who is not willing to admit that he knows nothing abou some
software).

Anyways, my question is this: how do you create larger partitions than the
original one that comes with Soft PC.  I was able to create a 5 MB "Drive D:"BuBut when I tried to access it, I got a "Non-DOS error."  I couldn't seem to
format the drive using the normal DOS format command.  There must be some trick
as to formatting the drive.  

So my question is, HOW DO YOU DO IT?  =)

There has got to be some alternative to creating zillions of small 1 MB partit-
tions by duplicating the original one.   It seems simple enough that you
can create one under the Hard Disk Command menu, but then What do you need to 
do in order to get the thing DOS formatted?

Also...another question: how is the performance of the AT/EGA add on.  I would
be buying it only for the speed upgrade as I only have a black and white SE/30.
IS the upgrade worth it?  How much faster?Q  Does it emulate a 287 also?  
What kind of 286 performance does one see: 10 mhz, 12 mhz, 16 mhz?

Any comments, suggestions, and answers would be greatly appreciated.

Please email then to me.

Thanks in advance.

I wouldn't be so tough on the guy.  The section of my DOS 3.3 manual that 
describes how to set up a new hard disk is 19 pages long.  The relevant 
section of the SoftPC manual is 9 pages long, easier to follow, but 
still takes a few minutes to digest if you are a Mac person used to 
plug-and-play hardware and single-mouse-click software installations.

The disk has to be prepared using the MS-DOS FDISK command.  FDISK
is a disk partitioning tool that is used to get around the DOS 
limitation of 32 megabytes per logical volume.  After running FDISK, 
each logical volume on the drive (usually one for SoftPC virtual disks)
can be initialized with the DOS FORMAT command.  The same thing would 
have to be done for a new PC drive.

I think that the AT/EGA extension adds considerable value to the package.
It IS faster, but more importantly it allows your Mac to emulate several
different PC hardware configurations.  You can do AT/CGA, AT/EGA, operate
with or without 80287 co-processor emulation, and use up to 4 meg of LIM 4.0
expanded memory.  This effectively gives you several different PC's in
a single package.  Switching between emulation modes is much easier than
reconfiguring a real PC.  The actual performance depends on the clock 
speed of the Mac, and whether background jobs are running at the
same time in another Mac MF partition (Multifinder compatibility is another
significant advantage of SoftPC over a real one or a NuBus PC board.).   
Switching to the PC is simple.  For example:

C:\> dir                               

 Volume in drive C is DOS_HD_C         
 Directory of  C:\                     

COMMAND  COM    25276   2-03-88   2:31p
DOS          <DIR>     10-18-90   9:37p
INSIGNIA     <DIR>     10-18-90   9:37p

Doesn't it make your skin crawl?

I fooled around with this as well. The details are vague since it was some time
ago, but the answer is another DOS utility which is maybe called fdisk.
This allows you to specify the volume setup after the disk has actually been
created.
