Hello!
I have to install Qnx 4.23A in a 13 gig HD - does anyone know exactly how
many gigabytes Qnx4.23A can “see” ?? The system actually needs less than 1
gig - it is an old installation, but you can’t buy “small” HD today. Do I
have to type in manually the number of cylinders ??
Thanks !

I think the only limitation you’re going to run into is the boot image one,
where the boot image must be below the 2G mark. If you want to access all of
the disk, I’d suggest making a small boot partition (as low as 400MB will work
wonderfully) with a partition type of 77 (hd0t77), then make the rest of the
disk one great big type 78 partition (hd0t78). When your system boots from
hd0t77, you just add to your sysinit file “mount /dev/hd0t78 /u” or whatever
you want to call it besides /u. Then away you go…
One thing we do, to make upgrading the O.S. easy (which looks like it’s
thwarted in the standard QNX6 install), is to put all of our “permanent” or
application data on a separate disk which is mounted as /u in our systems. We
have a smallish universal sysinit file which mounts the /u partition then execs
/u/etc/config/sysinit.<node#> which creates namespace prefixes to things like
/etc/passwd, and so on. What this allows us to do is shut down a machine,
yoink the boot/os drive which is in a Kingston removeable crive carrier, shove
in a pre-fabbed newer O.S. boot drive, and turn the machine back on. We’ve got
one machine that we keep up to date with build files, boot images and whatnot
for each node, and that’s what we build the o.s. drives from. It sure has made
our lives a lot easier.

I think Fsys.eide had a limitation so it would only see 8 gig. It was fixed in
one of the later 4.25 Updates.

Pre 4.25 only see 8Gigs, and actually if you have ANY type of partition
above 8Gig (FAT32 for example) the mount command will fail and you
won’t be able to boot or even install for that matter.

Perhaps you’re right (it’s been a while since I ran 4.23). I thought we had
mounted larger drives than 8 gig for quite a while, but I can’t say exactly
which version we were using at the time. I do recall there being an issue
with fdisk, where it was unable to handle one of our 70 gig RAID arrays
(something about a short integer…) and I thought that was 4.24… I may be
wrong on that too, though.

I think the 8Gig limit is cause by Fsys.eide not Fsys, so you whould see
this problem with SCSI.

Hi !It's true that QNX 4.24 and even 4.25A did not detect automaticaly the hard disk larger than 8 GB. However it's possible to specify the size of the disk at the biginnig of the installation. You have to know the number of heads, cylinders and sectors. Just after the boot type install -p "eide -c 255,2498,63". The numbers are for 20 GB hard disk, you have to put yours. I don't know if the mode is important: LBA, Large or CHS. I use the numbers from LBA mode. How about 4.23 version of QNX ? I don"t know. Just try install with these parameters.

Are you REALLY sure about that??? I think pre 4.25A EIDE driver did not support >8GB. At least that’s what my own experience show. QSSL can you confirm this?

You are right. I've just finished the test with 4.24 on whole 20 GB hard disk. It did not work.But I often use 20 GB hard disk to install dual boot system with QNX 4.24 and Windows 2000 and I divide the disk 50 / 50. So, QNX 4.24 is installed on 10 GB partition.Mario Charest wrote:

Was you Windows 2000 FAT or NTFS. I’m pretty sure that if it was FAT it would not work.

Win2k Doesn’t offer Fat or Fat32 during install, It’ll use whichever it needs.
Later in computer manager you can spec FAT or FAT32 for additional partitions.

When I said FAT I meant the FAT familly (FAT, FAT16, FAT32), my point
is that the 4.24 driver doesn’t know about NTFS so it may not event try to
mount it.
While if it’s FATXXX i will.
In my test if I installed even a 3 gig partion on a 10gig hd and the rest
being a 7Gig
FAT32 partiton ,the mount command will get VERY mixed up by the 7Gig
partion.
So badly mixed up that it won’t mount the QNX4 partition.
So I’m suggesting it my it work for Adam because his partition is setup as
NTFS.

not exactly, old qnx4 Fsys is confused by the fact of presence of any
partition
outsude 8gb border i.e. proper record in mbr. for example i had the same
well
known trouble when had to install free bsd as 2gb partition at the end of my
10gb hdd - Fsys said “amin” and crashed. so this is not as usually “ms bug”
but
this is a little mistake of folks created Fsys that leads to some
inflexibillity 
ps: well, thanks qssl this bug was at least partially fixed in newer qnx4
versions.
