Apple 640 manual Configuring drives C and D

The Sound Blaster card installed in your DOS-compatible Macintosh is not able to record sounds.

The DOS-compatible Macintosh does not fully support Sound Blaster 8-bit, Sound Blaster 2.0, or Sound Blaster Pro drivers. If problems occur, use the Sound Blaster 16 driver that comes with your computer.

Configuring drives C and D

You use the C: and D: pop-up menus to create or select PC drives. Drive C is required; drive D is optional. You can use a DOS-format SCSI hard drive attached to your Macintosh, or you can create a storage area called a drive container—a “virtual PC drive”—on any Macintosh hard drive. You can even use a drive container created by SoftPC or SoftWindows.™

To use a DOS-format SCSI drive as a startup (boot) drive, format the drive to be bootable by using the FORMAT C: /S command.

mTo create a drive container for drive C or D, choose New Drive File from the C: or D: pop-up menu.

Set a location for the drive container, and give it a name and a size. Then click Initialize Drive File.

When using a DOS-format SCSI device as the PC’s C or D drive, ensure that the driver for that device is not loaded by Macintosh PC Exchange. This would cause Macintosh PC Exchange to mount the drive instead of the PC environment. Open the PC Exchange control panel and click the Options button. Make sure the SCSI driver for the device you want to use is not checked. Then click OK. This ensures that the PC will be able to load the C drive.

Single versus multiple partitions: When you initialize a container this way, it contains a single partition. To initialize a container with multiple partitions, prepare it in DOS using the FDISK command instead of initializing it through the PC Setup control panel. Then format it using the FORMAT command. Use the /S parameter in the FORMAT command to make the container bootable (for example, type FORMAT C: /S at the DOS prompt). See the DOS manual for further instructions on using these commands.
