You cannot, since it is the driver's responsibility to register its
device at boot time. If no device is registered then either you have no
driver or it did not detect the CD-ROM drive. Look for a hardware
problem.

Subject: Millisecond timing under OS/2
Hi all!
I'm pretty new to programming stuff, so excuse any ignorance on my part
straight off. For my thesis I need a program to record reaction times
to 1 millisecond accuracy in Turbo Pascal. I have timing routines
which will do this, but I remember hearing somewhere that because OS/2
is a multitasking system, getting reliable recordings to the accuracy I
require is not likely to happen. Is this true? I would *definitely*
prefer to run my experiments under OS/2, rather than MS-DOS!!!
BTW The timing routines work by hooking onto INT 08 and INT 09.

use hardware to measure the interval. Pick up the result with your
program. Check out your physics labratory. There is uaually stuff
that you can set up over the HP GPIB or IEEE interface to do this kind
of thing accurately. (Those are measurement device networks that enable
your PC to talk to them - the measurements would be done by the
instruments without the active involment of your PC)
>timing routines which will do this, but I remember hearing somewhere
They will be unrealiable even under DOS. You will have no idea what is
going on in the backgrund, and how much delay kicked in. Unles you
want to be an embedded systems programming professional, you got no
chance whatsoever in doing an accurate job.

Interrupt latency can be up to 4 msec under OS/2 I heard by rumours.
There seems to be no official documents on that. Furthermore, it will
even depend on the video card you are using, as a blessing of
Microsoft...
However, supposedly there is a special driver allowing finer
resolutions, for example for profiling program execution. You probably
have to signup for OS/2 developers program, and buy the tools
necessary.
I think the Physics lab would have the gear necessary, and you can use
OS/2 to talk to the instruments and pick up the results of the
experiment. I am sure their lab person would be able to give you a
presentation on how they do it.

The fact that OS/2 is multitasking does not affect that point at all.

4ms? 400us is the MAX interrupt latency time that you can get on OS/2,
even on slow PCs.

get Watcom 10.5. It is cheap and comes with an OS/2 native High
Resolution Timer driver which uses the real time clock I believe. I do
not think that you need to signup for the Developper Connection for
OS/2 though.
Of course, the timer is programmed in C but you may hook to it in
Pascal I suppose. According to Watcom, the accuracy is on the order of
840 nanoseconds.

It is true that your routines won't be accurate, unless you obtain
special add-ons to OS/2 that allow accurate timing for events. There
are add-ons available from Indelible Blue or OS/2 Express for shop
floor automation that include these routines. I also believe that
there are ads in OS/2 Magazine for this kind of add-on as well.

No, rnews doesn't load the active file, it can't, since I allocate
memory outside the 64K stack for active file entries. Funny, I thought
I had made that a .EXE file again anyway.
You should be able to move back to the 1.12n rnews and use the 1.12p
newsrun.

I've now built a large history file and I'm going to be testing it.
I've already found one problem (the bad news group fix to 1.12o for
1.12p was incomplete), and I also need to fix the limit of simple news
group names being 18 bytes.
I also am looking at the truncation of the active file. It sounds like
entire trees are being lopped off.

This may not be your problem, but you might run a virus scan to see if
you have a virus on your hard drive. We had a problem similar to this
on two different computers running WFWG and they both had a virus. You

Subject: Solution to some Win-OS2 related problems
According to the latest issue of PC Magazine, when Intel created the
new generation of Pentiums, they were searching for a way to get the
DOS boxes faster access to the CPU. As such, Intel created a faster
method for switching to the DOS boxes.
Unfortunately, this new method is not 100% compatible with the old
method. As such, it can cause problems, when your Pentium switches
modes. (Protected to real mode, as one example.)
PC Magazine suggested turning this option off, and using the old
method, which is still there. You just have to explicitly tell your
Pentium this.
You can accomplish this by placing "VME=NO" at the bottom of your OS/2
config.sys file, and then rebooting.
They claim that trap 000e's and sys3175's and a few others can be
greatly reduced or eliminated.
One of the keys, is to check the date on your Pentium. IF it was
manufactured since about April/May/June of 1994, you will probably
benefit from this. If your Pentium was made before this, I imagine
this statement will confuse your CPU, but PC Magazine doesn't mention
this.
And yes, evidently this problem is a Pentium problem, NOT an OS/2
problem.
Anyway, thought some people might find this useful.

Subject: Warp Connect ??
Thanks to all that responded to my call for help regarding HD problems.
Since I decided to reinstall I thought I'd switch to warp connect since
it has TCPIP 3.0 thinking it would be better integrated - and it's main
thing I'm really interested in at this point. The installation went
just fine. The only problem is I'm not connected to anything - almost.
I can ping a host and I have connected to a unix box on our subnet but
that's it. LPR and FTP won't work. TN 3270 hangs. I suspect there is
something simple in the routing etc., I'm not seeing. I've double
checked the addresses. My NIC seems to be set up correctly - it was
recognized on installation (Intel ether express 16). Has anybody had
any experience with Connect using tcpip over their network at a
university? This should be simple and it was working fine (almost)
with tcpip 2.0 and warp. Also I now seem to have netbios and netbeui
installed. Is this really necessary?
PS. I downloaded fixpack 10 on another machine and would like to
transfer over except that I can't *connect* to the other machine @#$%!

Subject: Re: Warp Connect ??
Thanks to all those who offered suggestions on my hang problem with
Connect. I thought I'd post the solution I literally stumbled on out
of desperation since it might help others.
Several months ago I sent a defect report ot IBM for an NFS problem I
was having. Among other things that were suggested, one was to add the
following statement to the ifconfig statement in the mptn\bin\setup.cmd
file:
sendbuf 4096 recvbuf 4096 segsize 1024
I didn't use it for my NFS problem but it did solve my telnet, lpr,
etc. hangs! Things seem to be working fine now. Don't know if this is
unique to the EtherExpress 16 card, our network, or both.
I'm not looking forward to reinstalling NFS but here goes ...
By the way, has anyone else had trouble with NR2 shutting down on
opening?

Subject: Warp Connect Install doesn't work w/par to SCSI adapter
I am trying to install Warp Connect on a 486 using an external NEC 3x
CD drive and the MiniSCSI EPP APA 358 Parallel to SCSI converter.
I thought I could just copy the t358scsi.add file to installation disk
#1, but when I deleted a couple of files to make room for it, the
installation complained about them.
I'm hoping to use the 358 to install OS/2 on some machines that do not
have CD ROM drives. Is this possible?
Is there someplace I can find the info on this? The manual says that
the diskette will have a file named OS2.FAQ but it is not on my
diskette.
Thanks for any help.

Keith,
One hint - don't delete any of the files with IBM in the name. You
also need to REM out the drivers in CONFIG.SYS of Disk 1 you deleted
off of the disk. Also, add the line to support your T358SCSI.ADD and
also add the SET COPYFROMFLOPPY=1 line as well.
Try again and let us know!

If you are using c:\tmp as a work area, then you might want a different
\tmp directory. There should be one in your tcpip folder. If you
don't have one then you should create it and fix the TMP system
variable in your config.sys.
SET TMP=c:\tcpip\tmp
You probably know that sometimes WE leaves files hanging around so you
should check the \tmp folder once in a while and delete all the files
there.

Glen,
I don't think WFW will run in 2M RAM, especially when running the
network apps. However, you might try to maximize available memory and
system resources by trying some combination of the following:
1) disabling SMARTDRV;
2) not loading drivers and TSRs which are not essential in CONFIG.SYS
and AUTOEXEC.BAT;
3) stripping out unnecessary drivers and fonts in WFW; and
4) not loading other things like wallpaper, clocks, screen savers, etc.

You probably need a monochrome .RLE file for the windows logo. WIN.COM
is just a boot loader plus the windows logo file. Your error is
probably due to the color logo and monochrome adapter combination BUT
this is all probably a moot point.....
A quick peek at the WFW User's Guide (hint hint ;-} ) shows that WFW
needs a minimum of 3 Meg of RAM to operate on a network.

Thanks for the advice Jim. I got the machine running (temporarily) by
installing directly from the floppies. However that's a lot of disk
real estate for such a small hard drive. Now that you bring this up I
remember reading somewhere that you can build your own win.com and add
your own logo etc... maybe I'll have a look at the users guide :)

Can't always trust those things... when we set this network up the plan
was to run Q&A for DOS on the three workstations. The workstations all
(until now) boot and load the Windows network from floppies and never
actually run Windows. One 486DX/33 acts as file server and does run
WFWG.
The workstations perform quite well in DOS and really the extra meg of
RAM isn't used, except for the high memory area. Try to run Windows
however...
