SunPCi User's Guide

Emulated Hard Drives

When you install the SunPCi software, it creates a default C: drive and assigns it to an emulated drive file named C.diskimage, which resides in your ~/pc directory. By default, all SunPCi windows are booted from this drive C: and use the COMMAND.COM, AUTOEXEC.BAT, and CONFIG.SYS files located on this drive.

Note –

You can create several C: and D: drive files, all with different applications and configurations, and attach a drive as needed. Only one C: drive and one D: drive can be active at any one time. They may not be the same file; that is, do not attach a file as drive C: and then attach the same file as drive D:.

Creating and Configuring a New C: or D: Drive contains information on how to create and configure these drives.

Backing Up Your C: Drive

Once you have successfully installed Windows 95/NT, you can make a copy of the disk image of your C: drive. This allows you to keep a backup copy of the drive in case you need to recover the contents of your drive at any time.

Note –

We strongly recommend that once you have installed and configured SunPCi and your Windows applications, that you make a backup copy of your C: drive.

Your C: drive is actually a large file stored on the hard disk of your workstation. You use the SunPCi cphd (copy hard disk) command to make a copy of the file.

To back up your C: drive, follow these steps:

Locate the disk image of your C: drive.

It should be located in the directory called pc within your home directory on your workstation. To view the contents of the directory, type the following commands and press Enter after each:
```
% cd ~/pc
% ls
```
You should see a listing of files, including the name you assigned to your C: drive during installation (for example, C.diskimage).

Make a copy of the file.

Type the following command, substituting the name of your hard disk and the name you want to assign to the copy. Press Return.
```
% /opt/SUNWspci/bin/cphd C.diskimage C.diskimage.copy
```
