installation directory

Please help!

Is there any way to change the default installation directory from
drive:\program files\qnx to i.e. drive:\qnx? At install time or later, I
don’t mind. If I just simply move the files to any other directory (and edit
the config.sys to reflect the changes) then the boot fails with “./diskroot
cannot be found on any filesystems…” or similar.

I install QNXrtp from Win2k. I use only the dos part of Win98 and the
infamous “~1”'s are making me nervous.

Thanks,
Tice
