SunPCi Software Problems

Installation Problems

This section lists some possible problems with installing and running SunPCi software.

Table A–6 SunPCi Installation Error Messages


Error Message	Possible Cause	Solution
`Not enough disk space to install SunPCi software.`	Your workstation's hard disk or your home directory is out of space.	Delete unnecessary files, applications, or both to make more disk space available. If necessary, ask your system administrator for assistance. When you have created or obtained more disk space, start the SunPCi installation again. As an alternative, you can install SunPCi software on a different disk or system.
`You need additional swap space to install and run the SunPCi software.`	SunPCi software requires a minimum of 12 Mbytes of swap space.	Increase the amount of swap space on your system and then try installing SunPCi software again.

Software Startup Problems

When starting SunPCi software, you may encounter one of the following error messages.

Command not found: Make sure that the SunPCi program directory—by default, /opt/SUNWspci/bin—is in your environment PATH. Refer to Chapter 3, Starting SunPCi Software for the First Time for instructions.
Correct Solaris Installation Required

If you do not have the correct Solaris installation on your system, you will encounter problems when attempting to start SunPCi software. SunPCi software requires at least the End User System, Developer System, or Entire Distribution installations of Solaris versions 2.5.1 and 2.6 and Solaris 7. SunPCi will not run if you only have the Core System installed. Ask your system administrator for assistance in determining which system is installed on your workstation.

Windows 95 or Windows 95 Application Installation Problems

Whenever you install new applications on SunPCi, make sure you have your Windows 95 CD available. The installation program may require files from the Windows 95 CD.

Windows NT Problems

This section describes some problems you may encounter while using Windows NT.

General Protection Failures in Windows NT Applications

If your Windows applications show General Protection Failure or Null Pointer errors, you may need to install the Microsoft Windows Library update patch speu.exe. This patch is not included with the Windows NT software or with Service Pack 4. Information on the patch and the patch file are located on the Microsoft Web site at the following location:

Problems Installing to Network Drives

If you have problems installing Windows NT applications to network drives, try installing the applications to your C: or D: drives. The applications should then install correctly.

Recovering from Windows NT Setup

After you have finished installing and configuring Windows NT, you may want to use the Windows NT CD again at another time (for example, to view the Windows NT documentation on the disk). If you insert the Windows NT CD into your CD-ROM drive, an Autorun dialog box is displayed. This dialog box includes the Windows NT Setup option. Do not use this option to reinstall Windows NT; use the Add/Remove Software option in the Autorun dialog box or the Add/Remove Software Control Panel.

If you did select the Windows NT Setup option by mistake, select a different operating system in the OS Loader screen after SunPCi reboots. For example, choose Last Operating System on C:.

Creating Windows NT Repair Disks

The boot floppies that come with the Windows NT Workstation package do not contain the SunPCi drivers. If you try to use these repair disks to recover from a Windows NT, the SunPCi drivers will not be installed and the software will not work correctly.

If you want to create a repair disk for your SunPCi installation of Windows NT, perform the following procedure:

From the Start Menu, choose Shut Down, and then choose Restart the Computer.

Click OK.

Windows NT shuts down and restarts.

At the OS Loader screen, use the down arrow key to select Previous Operating System on C:. Press Return.

SunPCi then boots into DOS. When it has finished booting, the DOS prompt (C:\>) is displayed.

Back up the following files to another area on your workstation's hard disk or to a floppy. These files are needed in order to initialize the MS-DOS environment.

C:\winnt\system32\Autoexec.nt C:\winnt\system32\Config.nt

Copy the following files to a floppy disk. If Windows NT Workstation 4.0 does not start up, you will need this floppy in order to boot Windows NT.

C:\Ntldr C:\Boot.ini C:\Ntdetect.com C:\bootsect.dos C:\Hal.dll

You might want to make more than one copy of this floppy, in case one copy is damaged or lost.

Copy these registry files to a directory on your workstation's hard disk (such as $HOME/temp). You will need these files to restore the Windows NT Registry.

C:\System32\config\Sam C:\System32\config\Sam.log C:\System32\config\Sam.sav C:\System32\config\Security C:\System32\config\Security.log C:\System32\config\Security.sav C:\System32\config\Software C:\System32\config\Software.log C:\System32\config\Software.sav C:\System32\config\System C:\System32\config\System.alt C:\System32\config\System.sav C:\System32\config\System.log C:\System32\config\Default C:\System32\config\Default.log C:\System32\config\Default.sav C:\System32\config\Userdiff C:\System32\config\Userdiff.log

Note –
You may not have .sav files in your directory. This is normal. However, if you do have .sav files, it is a good idea to back them up.

Copy these files to floppy to restore the default user profile:

C:\winnt\profiles\Default User\Ntuser.dat C:\winnt\profiles\Default User\NTuserdat.log

Note –
In DOS, the directory will appear as C:\winnt\profiles\Defaul~1\.

Using the Repair Disks

When you need to recover Windows NT, follow this procedure:

Insert the floppy with the DOS files you copied into your floppy drive and then start SunPCi.

Your SunPCi window will boot to the DOS prompt.

Note –
If you have trouble booting to the DOS prompt and you have the MS-DOS 6.22 diskette available, insert the DOS diskette into your floppy drive and restart SunPCi again.

At the DOS prompt, copy the files from the other floppies back into the directory paths specified in each of the steps.

Copy the files you stored on your workstation's hard disk into the specified directories.

When you have finished copying all of the saved files into their respective directories, choose File and Reset PC to restart SunPCi.

SunPCi boots into Windows NT.

If you have trouble booting into Windows NT, insert the floppy with the Windows NT boot files that you created in Step 1 of the previous procedure in your floppy drive and restart SunPCi again.

Windows NT should boot from the floppy; press F3 to boot to the DOS prompt. You can now recopy the Windows NT boot files from the floppy disk onto your C: drive.

Note –
If you need to restore the Windows NT system password files only, restore the following files: C:\System32\config\Sam C:\System32\config\Sam.log C:\System32\config\Sam.sav

Emulated Hard Drive Problems

Attaching Drive C:

To be sure that you will always be able to attach drive C:, you can change the permissions on the drive. Changing the permissions will keep other users from being able to attach drive C: even when you are not using the SunPCi program. To change permissions on drive C:, type the following in a command window:

% chmod 600 ~/pc/C.diskimage

This makes the drive inaccessible to other users.

Disk Error Messages

If your SunPCi window shows the message Non-system disk or disk error at startup, your C: drive may have been corrupted, or you have a non-bootable floppy disk in drive A:. If you do not have a floppy disk in drive A:, delete the default C: drive file in $HOME/pc and then restart SunPCi.

You may want to make periodic backup copies of your C: drive. Refer to Backing Up Your C: Drive for more information.

Extended Drive Problems

Cannot Mount Extended Drives With Windows Explorer

If you cannot mount extended drives, networking may not be installed on SunPCi.

Try to log in to the network first. If you can reach the network from the UNIX side, then go to the Start menu in SunPCi and select Control Panel, then double-click on Network. Set up your SunPCi installation on the network. Refer to your Windows documentation for more information.

If you still cannot connect to the network after logging in, you will need to reinstall Windows 95.

To log in to the network, follow this procedure:

Start up SunPCi and enter your user name and password when the dialog box prompts you to log in to Microsoft Networking.

To log in to the network if you are already running SunPCi, follow these steps:

Click the Start button and then select Exit.

When the dialog box asks you whether you want to shut down or restart the computer, click on Restart.

When the Microsoft Networking dialog box appears, type in your user name and password and press Return.

You will then be able to mount extended drives. Refer to Extended Hard Drives for instructions on how to use Windows Explorer to map network drives.
