Hanging on Boot

Like some others I am getting trouble after crttrap starts up. It shows an
attempt(?) at three different drivers. I have a Voodoo 3 3000, with
on-board chip which is turned off in Win 98. Running a Compaq so ability to
use BIOS is limited so unsure if it is turned off at that level. If I boot
in safe mode and run crttrap at the command line I receive info that there
is a corrupted file system in the graphic-modes area (think it is
specifically /etc/config/drivers/graphic-mode?). I had previously used the
preceding release with no trouble at all. Any thoughts on this or
suggestions for trouble shooting. I am not at all familiar with QNX command
set so am stumped for now. Dave Danforth
