When I try to install my CRSP database on DVD, I get an error message that the setuplinux.bin or setupsolaris.bin files are read only and cannot be executed.

CRSP creates DVDs with a "hsfs" default. If you get the "read only" error message, most likely your DVD reader is mounted as "udfs" and will need to be remounted as "hsfs" in order for the CRSP DVD to be read.

Your system administrator should be able to remount the drive with little effort.

To diagnose and confirm that this mounting difference is the problem, execute the following commands:

1. Load the DVD onto your drive on Unix or Linux.
2. Type the following command:

   For Unix

   df -n

   For Linux

   df -T

3. After typing the above commands and pressing enter, the drive that mounts the DVD should list as "hsfs". If it lists as "udfs, the drive needs to be remounted as "hsfs".

To make the change permanent on a Solaris 10 system, edit /etc/rmmount.conf and remark the following line by placing a hash mark in front of it:

#ident udfs ident_udfs.so cdrom floppy rmdisk

Save the file. It is a read only file so you will need root privilege to change it. You can use the :x! or :w! options in vi to save the changes.
