Your system definitly needs more RAM, and a larger harddisk will
make things much easier for you then setting up something on
your current system. Follow Warren’s instructions, they are
right on the money and the easiest

You mean to say that 8mb is not enough for a minimal RTP install that does
nothing but start Photon & the ICA client? I was running X on 8mb & 16mb
systems back when Linux first started, so 8mb on a much more efficient GUI
platform and leaner OS should easily be possible. At least in a 640x480 16
mono/256 color resolution like I’m interested in working with.
No idea what the original poster had in mind, but if it is at all like what
I’m doing and you aren’t trying to do a full RTP install onto the thing,
only enough to boot to photon & run ICA, both the RAM and HD space seem
fine. I’d like to target <32mb HD/flash total needed, myself…
Because there isn’t a floppy-only barebones RTP install, and the current
install doesn’t know about SCSI CD-ROMs at install time, I’m stuck in a
chick & egg problem with it at the moment. But given the same hardware can
run Linux+X it seems unlikely that RTP would be unable to have enough
resources…

DOS drivers do not exist for a lot of the hardware I have or that I’m
interested in using. As I said 8mb was fine for Linux+X, and with
QT/Embedded I could likely do without X altogather. I’d rather use QNX
though, since the GUI is better and the OS kernel in RTP is better suited to
running in small memory than Linux’…
I don’t know about the original poster but I actually can get 16 or 24mb of
RAM into most of the old hardware I have, so even if 8mb isn’t workable it
should still be usable. I was just commenting that 8mb should be usable
since it is with a more bloated OS and bloated GUI…

I’m assuming that since the original poster didn’t mention anything about
trying to strip down the installation that he wanted to take the easy route and
just install from the CD and away he goes. By the time you get done loading
all of the stuff that gets kicked off in the standard install, no I do not
believe that 8MB RAM is going to be enough. Just the help files are huge, plus
the plethora of utilities and whatnot are going to eat up a whole lot of the
hard disk space.
If one were to take the time to learn how to strip out all of the unneeded
components, I’m certain that the disk space would be more than adequate.
Moreover, with some trimming, it’s more likely than not given a reasonable
resolution/color depth that Photon can be made to run. Running the Citrix ICA
client on such a system however, is a total shot in the dark. I don’t have any
idea what the memory requirements would be, but I’m guessing that it’s going to
be pretty tight in there with only 8M.
If you really want to find out what exactly is needed, you’d have to do an
install on a “regular” well equipped desktop PC, then cut out a suitable
install for the more restrictive hardware and see what you can get away with.
But the short answer still stands for a standard install: More RAM and a bigger
disk.

You could look at building a boot floppy with the SCSI support built into it,
unless for some reason the SCSI driver just plain doesn’t support CD-ROM. As I
understand it, it’s “diskboot” that doesn’t support the SCSI stuff yet. There
are SCSI drivers, and if your hardware matches one of these, then you should be
able to hack something together pretty easily (note that easily is a relative
term 
.
Your best bet is to start with a fully installed system, then just cut & paste
the parts you want. You can make things absolutely tiny if you do it this way.
The CD install is quite huge compared to what you can get away with. In my
embedded thingie, I can get a system up & running with a shell and a few
commands in under 384k (everything in the compressed boot image).

QRTP IS A DEVELOPMENT ENVIRONMENT AND IS NOT MEANT TO BE EMBEDDED!
Sorry 'bout that but this is a very common misconception. The QRTP
is meant as a self hosted development environment and is not meant to
be embedded directly. We (QSSL) have no way to determine your particular
needs and wants for your particular embedded system … only you can
decide what you need. What you can do is install QRTP on a system which
can support it properly, then pick and choose to make a custom image
that suits your application. We have a whole “book” in the QRTP help
aptly called “Building Embedded Systems” that deals with this (Note
we haven’t quite got the “embedding photon” section writte up yet).
That said anything we can do to help you … let us know.
Because there isn’t a floppy-only barebones RTP install, and the current
install doesn’t know about SCSI CD-ROMs at install time, I’m stuck in a
chick & egg problem with it at the moment. But given the same hardware can

resources…
What would a floppy-only barebones install mean? You can write a barebones
floppy install with the following build script:
–
[virtual=x86,bios +compress] boot = {
startup-bios -v -Nthomasf
PATH=/proc/boot LD_LIBRARY_PATH=/proc/boot procnto -v
}
[+script] startup-script = {
display_msg Starting Neutrino
devc-con &
reopen /dev/con1
reopen /dev/con1
[+session pri=10r] SYSNAME=nto PROCESSOR=x86 PATH=/proc/boot:/x86/bin:/bin esh &
}
[type=link] /dev/console=/dev/con1
libc.so
[type=link] /usr/lib/ldqnx.so.1=/proc/boot/libc.so.1
[data=c]
devc-con
esh
Granted you can’t do anything with this, but if you run mkifs on this
file and then dinit the image onto a floppy you can boot Neutrino. If you
are interested in a single floppy demo-disk style thing, then be patient
it will come.

Other then the standard libs that the ica client requires
(c,ph,phrender,socket) it’s only ~280k code and the data
can be trimmed by not specifying memory cache…

Did you have swapping turned off on this Linux+X system?
Marisa
It can be done, however the RTP as it ships assumes you have atleast X amount of
memory, you would have to do a little bit of work to get it going under 8MB, but
it can be done. The quickest route is to just get more RAM. He could boot up
the RTP without going into Photon, then start to tailor it to his RAM
requirements. A good start would be to take a already running RTP system
bring up a terminal window and type pidin. Check to see what processes are
running and start to kill them off. When something goes very wrong, then
you know that you need that process to run Photon (e.g. Don’t kill the process
“Photon”, but something like pwn may not be nessisary for the persons needs).
When you find something that you don’t need to run, then start to either
edit the rc.sysinit and other startup files, or start to make a new one with
just your requirements on it.

That’s where I’m stuck on now. I have been able to get the PCMCIA hard
drived recognized on a more normal laptop RTP install, and can fdisk/dinit
them fine. What I don’t know now is how to go about building up the more
restricted install image to put on the drives.
Is there anywhere in the online manual that covers how to create a
customized image like that? Just as a test I tried copying over the
/.altboot etc files from the working system onto the PCMCIA drive, but when
the target system is booted with it the screen goes blank (blinking cursor)
after the BIOS & POST tests…
But the short answer still stands for a standard install: More RAM and a
bigger
disk.
For sure, I wouldn’t expect a full install from the CD to work on a 4mb
system…

Well in that case you will have to additionally run devb-xxx (probably
eide), include dinit and fdisk and the appropriate libraries for the
filesystem and block driver. Note that if you set DL_DEBUG=1 as an
environment variable in your start-up script you will be able to see
what DLL’s are attempted being loaded. You will need to ensure that
those dll’s are present in the image. Since you have RTP installed,
I would suggest going through “Building Embedded Systems”, it explains
all you need to know about making images.

Certainly not an impossibility … but where would it connect to? Presumably
your server internally in your company. Since we haven’t officially doced
the “package repository” process (though it isn’t rocket science) it
would be awkward to do this right now.

I am trying to do this right now. Only problem is I can’t figure out where the
system configuration files are that control what photon loads. rc.sysinit doesn’t
seem to be the one.

A co-worker actually has put together a few good examples of embedding
RTP on a system. You can find the information here:
http://staff.qnx.com/~cforan/embed.html
Even if you don’t want to go through with the level that he
went through, you can always go through the examples to learn how
things work.
