QNX Install Program Hard Drive Parameter Detection

The QNX (4.25) install program does not detect the correct hard drive
parameters for our new Hitachi model DK239A-48, 4871 MB hard drive.
Previously we have used both a 2 G (4188 Cyl, 16 Heads, 63 Sectors) and 4 G
Toshiba hard drives successfully.

Parameter Detected Actual
======== ======= =====
size (MB) 4645 4871
cylinders 9438 10068
heads 16 15
sectors 63 63

Calculated capacity based on the above, (bytes):
Detected: 4,870,914,048.
Actual: 4,871,301,120.

The command line: install -p “eide -c heads,cylinders,sectors” (e.g.
install -p “eide -c 15,10068,63”) doesn’t work. The install program reverts
back to the detected parameters. However, the everything seems to work
fine - the installation program completes and the hard drive boots correctly
to QNX.

We did a test filling the hard drive with 900MB with a few large files with
the command “cat filex - >> filex” a few times (took almost an hour before
we stopped them with ^) Then we copied over several executables and they
all ran flawlessly. At the very least, can we count on 900MB of disk space
before any problems arise?

My concern is that without the correct settings, the drive may seem to work
initially and then crash at some later date. Does anyone have any thoughts?

Thank you,

Try to put the lates Fsys.eide version to yours boot disk.

Thank you for your advice. I downloaded drvrdiskide.144 from the QNX web
site, and created a bootable floppy which has the latest drivers. Fsys.eide
is from 1999, only about a year newer than the one that came with ver. 4.25.

I have not tried booting from it yet because the units with the hard drive
are an embedded system of ours, and they are currently in our production
dept. I assume when booting, the installation program will run, as per
“drvrdiskide.txt”.

What does the install program do? Does it create an updated boot image on
your hard drive with the new Fsys.eide? Could that somehow screw up the
existing partition which was “created” with the old Fsys.eide?

Also, this still does not give me an updated installation disk set. Those 5
disks (not counting the boot disk) are specially formatted and are
unreadable as /fd0. I was hoping to replace Fsys.eide with the new one, but
no dice.

Thank you for your advice.

This is a addendum to my previous posting. I downloaded
qnx425.diskset.tar.F. I see that it is the new Installation Disk Set. But I
would still appreciate a reply to my first questions about updating existing
hard drives with the new Fsys.eide.

Thanks.
