Known Problems and Limitations

Because the Adaptec AHA-1542CP and the Solaris fdisk program may be incompatible, use the DOS version of FDISK (or equivalent utility) to create an entry in the FDISK partition table before installing the Solaris software. Create at least a 1-cylinder DOS partition starting at cylinder 0. If the DOS partition is not created, the system won't reboot after Solaris installation.
