Due to a bug in SCO's CDROM driver, the CDROM delivered with Power Tools has a problem executing two files directly from the CDROM. SCO has generously allowed us to include the fix on this CD. The Driver.o module repairs the executable problem with SCO UNIX and CDROMs. Here are the steps to install the CDROM driver fix: 1) Make a backup copy of the existing Driver.o cp /etc/conf/pack.d/hs/Driver.o /etc/conf/pack.d/hs/Driver.o.save 2) Copy the new driver to /etc/conf/pack.d/hs cp Driver.o /etc/conf/pack.d/hs/Driver.o 3) Relink the system cd /etc/conf/cf.d link_unix You will need to reboot your system to begin using the new driver.
