Dont apply the kernal refresh !!

Use Daniela's ldr patch   patchldr.zip

It's on hobbes, leo, and here.

Thanks Ian, that was a great solution. No great dramas applying it. We would all be
sunk without Daniela. She needs a medal of some sort.

G'day all,
Recently I held a small P.D. session for some of the guys at work to do with system resources and the like. I 
liberated the laptop which I installed OS/2 on and proceeded to prepare for the presentation.  After plugging in 
all the connections to the external projector and booted up, I found that the LCD display would not operate, 
only the CRT out.  They both worked through Windoze.  In fact none of the Laptop's "Fn" keys were 
accessable. Is this some kind of "Designed for Microsoft Windows" type of hardware thing?

Here's what I used:
A REALLY old Texas Instruments 510CDT
Warp 4 fix 9
Chips 'n Tech 65550 disp driver (version ????)

Incidentally, I used Star Office 5.1a for the presentation and was a complete success, despite no LCD.  :-)
4====================================
Warp 4 has always been able to see more than 64MB of memory. 

I think the Kernal upgrade you refer to is the inclusion of the 
Aurora (WSeB) kernal into the client, to allow direct addressing of
over 256MB of virtual address space (this limitation stopped several
Windows programs from working under Odin but apart from that didn't
cause "normal" users any real problems).

There is often a setting in your CMOS for OS2 > 64MB - this goes back
to the days of OS/2 1.x and I tend to leave it in its default (off)
position. The machine I am using now has 128MB of memory and this option
off.

Regards,

Ed Durrant.

5====================================
When you say LCD, do you infact mean a LCD panel that goes onto an 
overhead projector ?

The issue where only the inbuilt laptop's LCD display OR the external
Monitor/LCD Panel/Projector will work, is usually a hardware issue
rather than a software one. If the feed to the external device is
too much for the video chip, this will often occur. Several of the
better (and hence more expensive) projectors have an extra buffer
amplifier on their video input to avoid this problem. There are also
"after market" external amplifier/splitter units that you can buy to
do the same thing.  Although why they should work under Windoze and
not OS/2 evades me unless it is a video driver issue.

Normally what a Fn key does is also defined by the PC manufacturer. A
Fn key is not a windows keyboard type key.

Hope I understood your problem correctly and thrown some light on why
it may be happenning.

Regards,

Ed Durrant.

Not quite right.
SOME bios'es in SOME machines, usually produced from about 2 years ago,
were unable to allow os/2 to see more than the first 64mb of ram.
This was because these either did not offer a choice of the bios
memory setting Ed is refering to, or were false in this regard.

That is why Daniella produced her patch file
as Ian Manners said, quote:-

 "patchldr.zip".

It's on hobbes, leo, and here.
http://www.os2site dot com/sw/upgrades/patches/

end quote.

All newer motherboards available today should have the correct
setting in the bios and it SHOULD function correctly.

The kernal upgrades are for Fixpak #15 and WSeB and eCS and MCP
(more accurately now known as CCP = IBM Client Convenience Pack)
and ONLY these systems.  No one should use these kernal upgrades
unless you are at these levels.

The kernal upgrades were originally meant to fix problems with
fixpak #15 level code (ie eCS, MCP or CCP, Fixpak #15 itself).
One of the more serious problems was inability to boot on non
pentium systems. ie 486 cpu's etc.

Recently, they introduced the fix for the os2 loader "os2ldr"
which is to be installed _ONLY_ IF you need it on YOUR system.
I don't now why they included the os2ldr fix in with the
kernal fixes, but perhaps it was the simplest means of distribution.

This "feature" is fully documented in the kernal upgrade files.
I have installed the kernal fixes on my Pentium 3 800mhz and 
they work real good.  :)


If anyone following this discussion, wants to check their
system to see if their memory is being fully utilised, Daniella
also provides in her patchldr.zip file a DOS execute-able that will 
do a memory test for you.

You MUST run it in a DOS box, OR with a batch file with a pause 
statement as the last line.
