CD-ROM Drive Problems

This section describes possible problems you might encounter with Windows 95 or Windows NT and your CD-ROM drives.

Problems with Windows 95

If you are trying to access Solaris files and CD-ROM drives from Windows 95 and you are unable to use the Map Network Drive command in Windows Explorer to set up the drive, be sure to check the following:

Make sure you have the CD in the CD-ROM drive. This is the most likely reason that a drive mapping may not work.

Make sure you entered the path for the CD-ROM drive as \\cdrom\cdrom0, with two backslashes at the beginning.

Problems with Windows NT

Table A–4 describes some problems you might encounter with CD-ROM drives, possible causes, and solutions.

Table A–4 CD-ROM Drive Problems in Windows NT


Problem	Possible Cause	Solution
When you insert or eject a CD in one CD-ROM drive, the other CD-ROM drive becomes unreachable.	You have two SCSI CD-ROM drives in your system.	You will need to select which CD-ROM to use with SunPCi. Refer to Setting Up Your CD-ROM Drive.
When you double-click on the CD-ROM drive in Windows NT Explorer, you get the following error message: `Drive not ready. Abort/Retry/Fail?`	Your workstation's Open Boot PROM (OBP) is out of date. Your CD-ROM drive may not be a Sun-supplied drive.	Update the OBP as described in OBP (Open Boot PROM) Problems. SunPCi only supports Sun-supplied CD-ROM drives. Replace the CD-ROM drive in your system with a Sun-supplied drive.
Playing an audio CD in Solaris using the `workman` utility causes Windows NT to hang. Starting Windows NT while an audio CD is playing pauses the audio CD.	Your CD-ROM drive is being shared by both Solaris and Windows NT. As soon as Windows NT detects the presence of the CD, it pauses the CD.	Disable CD detection in either Solaris or Windows NT. The CD cannot be shared by both operating systems. Note that once you have disabled CD detection in one operating system, you will need to mount the CD manually in that operating system.

Setting Up Your CD-ROM Drive

If you are not using Solaris Volume Manager (vold) to control your CD-ROM drive or if you have more than one CD-ROM drive, you will have to specify which drive you want to use with SunPCi. To set up your CD-ROM drive, perform the following procedure:

Start SunPCi, if it is not already running.

The console window from which you start the application displays the following message:
```
sunpci: Your SunPCi.ini file does not specify a CD device
        assuming /vol/dev/aliases/cdrom0
```

From the Options menu, choose Attach CD-ROM.

The Specify CD-ROM Device File dialog box is displayed.

Type in the path to the CD-ROM device you want to use (for example, /vol/dev/aliases/cdrom0).

When you have finished typing in the path, click OK.

Exit Windows NT and reset SunPCi.

When SunPCi restarts, it will use the CD-ROM drive device you specified.
