Setup From CD Might Fail On The Compaq SystemPro XL

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

Setting up Windows NT or Windows NT Advanced Server from the CD-ROM drive on the COMPAQ SystemPro XL with the embedded SCSI controller IRQ set to 2(9) will make the computer stop responding (hang) at the status message "Running CHKDSK" after Setup has formatted the newly-created partitions.

CAUSE

The COMPAQ SystemPro XL with an embedded SCSI controller is detected as a NCR53c9x during setup. If the CD-ROM drive is connected to this controller, there is a known problem if the controller is configured in the EISA configuration using IRQ 2/9.

RESOLUTION

Reconfigure the controller to use any other unused IRQ such as 5.

To reconfigure the controller to use another IRQ, do the following:

1. Run the COMPAQ EISA Configuration Utility.

2. Choose Configure Computer.

3. Choose View Or Edit Details.

4. Press the PAGE DOWN key or the DOWN ARROW key to select Controller.

5. Press the F6 key to "Edit resources."

6. Change "Interrupt (IRQ)" from 2(9) to an unused interrupt. (5 is often unused).
