Non-emergency question about QNX partition

I run Win2k pro on my main partition and QNX on the second partition. I
already added the QNX to my NT boot loader so there’s no problem, but I had
a quick question.

Is the partition that QNX gets installed to always named hd0t79 if it’s
installed to the first hard disk? I know when I installed OpenLinux before,
I would have to go into the lilo.conf file to find the name of the boot
partition because it changed when it was installed to different partitions.

If the QNX partition name changes for different partitions, then where is
the QNX equivalent to lilo.conf so I can find out the boot partition when I
reinstall it later?

You are using ntldr and you’ve added something like

C:\bootsect.qnx=“QNX RTP”
in your boot.ini.
Am I right?

Yes, you could see hd0t79 under /dev/ for QNX partition on first HDD and

hd1t79 for QNX partition on second HDD… I have a FAT boot partition in my
system and I see hd0t6. I believe the partitions are named
hd<#HDD>t<#Type>, where <#HDD> is a number of hard drive, <#Type> - code of
file system (it is included in MBR, for example 6 is a code for “big” FAT
partition, 5 - extended DOS, 4 - “<32MB” FAT and so on)
I heard about types of partitions 77 and 78 in QNX, but I know nothing
about these types.
So, partitions names in QNX will not be changed if you will add the new
partition to your hard drive (in contradistinction to Linux and Win2k).

If the QNX partition name changes for different partitions, then where is
the QNX equivalent to lilo.conf so I can find out the boot partition when
I
reinstall it later?

Linux loader is a very different from QNX loader. As far as I understand

you don’t use QNX loader at this time. Ntldr loads “bootsect.qnx” into RAM
and passes control to this code. So, you must update “bootsect.qnx” if boot
sector of QNX partition is changed. For example, it happens during QNX
upgrade, or (I’m not really sure) if you move QNX partition (e.g. reinstall
QNXRTP).
Anyway, AFAIK, QNX loader does not use any configuration files.

I guess the types 77 and 78 are the same as 79. And it is pay for constant
partition names, because no other way to creat few QNX partitions on a hard
disk. Maybe, anyone from QSSL corrects me … ?

Hi,

You are correct in saying 77, 78, and 79 are the same. Type 77 is the default for QNX4 and
79 is the default for QNX 6. QNX 6 will only install to type 79, after the install you can change
the type to 77 or 78 with qnx ‘fdisk’.

ie. If you want more then one QNX 6 installed on the same hard disk…install QNX 6,
change type from 79 to 78, install second QNX 6.

Joe

Hi,

What about partition’s names under /dev/ when more then one partitions the
same type on disk? I have only one partition FAT16 on disk and it’s
automounted as /fs/hd0-dos. The FAT partition seems as hd0t6 under /dev/.
Will I have problem in accessing to FAT partitions if I will creat the
second FAT partition on drive?

Thanks in advance,
Eduard.
