Win2000 screws QNX 6.0 filesystem?

Hi! I have QNX 6.0 installed in its own primary partition from the
bootable CD-ROM (part id=79). Everything was going fine until I also
installed Windows 2000. During instalation (but also afterwards in every
single boot) Windows 2000 checks disks partitions and filesystems, it
thinks that the QNX partition contains a FAT filesystem, begins checking
it and gives up realizing it cannot cope with it. After that Win2000
works normally. On subsequent boots it does not check the QNX partition
any more. However, when I try to bring up QNX afterwards, photon does
not start. The screen goes into graphical mode but remains black :frowning: By
pressing Shift+Ctrl+Alt+Backspace I can get a prompt and in command line
things seem to be working fine. But photon insists on doing the same
thing upon issuing “ph”.

When I restore the whole QNX partition from a “dd” backup QNX works fine
again, up until I boot into Windows 2000, when all the above repeats.
Does anybody know how to stop Windows2000 from checking the QNX
partition?
(some flag in Win2000?, a change in the QNX partition signature? some
other fix? Linux and its tools are all available for doing fixes… I
haven’t tried QNX 6.1… does it solve this? )


thanks in advance,

Sakis

There have been several versions of windows that boot up, look at the
partition map, say “I don’t recognize this partition, therefore I’ll change
it!”

Not really :\ Windows keeps checking it from time to time.
But I don’t have any problems with Photon.

Launch ‘regedt32’ and look at REG_MULTI_SZ element
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\BootExecute

Remove autocheck or pass some switches if there is any :wink: NT4 doesn’t check unknowen partitions,
but NT5 seems to be more sophisticate :wink:
Report this problem to Microsoft, but you’re lucky it didn’t try to convert the partition in NTFS5
filesystem :wink:
