PS, this would probably be the same one you used so dont expect it to
work on large drives :(

IIRC both HPFS & HPFS386 have a 64Gb limit with a 2Gb filesize limit.
There is a table in an IBM .inf comparing file systems.

I don't think that it can be done directly.

When a programs loads a DLL, either statically (via the import records in
the header of the exe/dll) or dynamically (via DosLoadModule()) the dll is
locked and can not be written over.

Once a dll is loaded, any other process that requests it is given it's on
data segment instance, and runs the same code from the dll (be it already
loaded in memory or loaded in from disk).

This prevents a process from overwriting dll's that are in use.

However, there is a function call (I can not remember what it is called)
that forces the entire dll into memory and does then allow you to overwrite
the dll on disk.

This dll injection could not work first time around, but if it loaded the
dll into memory and overwrote the disk file, then it could work. The new
dll would be available at the next boot, or possibly even before that, if
all processes that were using the dll terminate (I'm not sure of what
happens to the dll that was loaded into memory then, but I would think that
it will free up the memory).

Hence, it may be able to be done indirectly.

These are from dos, so why do you need it?

To be totally correct. The HPFS has a design limit of 64Gb. The current
implementations allow for this. The earlier HPFS versions could not cope
with disks this big. There were not enough bitmap sectors allocated to cope
with 64Gb. Now they just left them flow on and be as big as they need to
be.

Remember that the HPFS was designed in the 1985-1986 period, when (from
memory) 80Mb disks were pretty cool (and expensive!)

JFS uses 64 bit pointers, and thus can cope with >4Gb files. The HPFS by
itself can not.

Hi Chris,

Thanks for the previous explanation - which I have just posted on os2user.

It looks like you can now pre-order 1.2 from BMT Micro and Mensys.

Is the Orion Solutions site still up?  I couldn't connect to it.  Are they still in the ecs - os/2 business?

Hi David,

Guess that you have read the announce12.pdf about eCS 1.2-AppPack 
1.2-SVISTA/2 from the www.yahoogroups dot com/ecomstation group's files area 
before Bob St. John pulled it, because he didn't realise that the Binner 
Gothic font was missing - hence the stylised eComStation 1.2 text on the 
cover and all page headers
was garbaged!

I can't connect to either www.ecomstation dot com dot au or 
http://www.orion-solutions dot com dot au currently, so I'm wondering too? :-\

[also sent p-mail in case you only get one digest a day!
As one needs to be subscribed to the group to access the file - let me 
know if you want me to forward the 43K .pdf]

Mike
