However, some I/O Kit drivers link with more than just I/O Kit (for example, a disk image driver must necessarily link with BSD to get access to the file system), and these drivers have the same problems as other (non-I/O Kit) KEXTs on 10.4: they must be ported to use the KPIs. can any body help me what could be the problem, errors are shown in this way The log message isn't particularly helpful. Try loading your driver with "kextload -t". This produces more helpful debugging output. This email sent to site_archiver@lists.apple.com
