If you have either Apple RAID striped, or mirrored volumes on a Workgroup Server 9150/120 with an internal Panasonic (also known as MKE) CD-ROM drive, the server may freeze during startup from a bootable CD-ROM disc. This may happen even if you have installed Macintosh CD-ROM Setup 5.1.1 or later on a Workgroup Server 9150/120 and then try to startup from the startup CD disc that came with your server.
This is because the older CD-ROM driver, version 5.0.3, will be loaded from the startup CD disc, which may cause the server to freeze. Typically, if a Workgroup Server freezes during startup from the startup CD, a hardware problem might be suspected since the startup CD is considered a "clean" system. However, with the older CD-ROM drivers on the CD, a startup floppy disk should be made to let you startup the server in emergencies. A startup floppy disk can be made by following the following steps:
1. Create a disk tools floppy from the image on the Workgroup Server 7.5.1 CD.
2. Delete the CD-ROM Setup 5.0.3 extension from the Extensions folder in the System Folder on the Disk Tools disk created in step 1. Select the Empty Trash command from the Special menu.
3. Drag the CD-ROM Setup 5.1.1 extension to the Extensions folder in the System Folder on the Disk Tools floppy disk.
4. Keep this Disk Tools floppy for emergencies to startup the Workgroup Server 9150/120.
