Chapter 3 Installing Microsoft Windows NT 4.0 Server Tip #1. Troubleshooting SCSI Host Bus Adapter Configuration The boot manager for Windows NT contains recovery logic to allow you to return to the last known good configuration. If you have changed your SCSI host bus adapter configuration and Windows NT no longer boots, follow these steps to recover: 1. Undo any hardware changes you have made to the computer since it was last operational. 2. Reboot the computer. Press the spacebar when the message appears: Press spacebar NOW to invoke the Last Known Good menu. Follow the instructions on the screen to continue booting. NOTE Do not log in if you pass the "Press spacebar NOW to invoke the Last Known Good screen" option, because this will wipe out the configuration you want. 3. Once your computer is operational again, double check all the hardware and software configuration changes you wish to make. Look specifically for conflicts with parts of the existing system configuration that are not being changed. If you cannot determine the source of the error, contact the host adapter vendor or HP Technical Support for assistance. Tip #2. NT Warning About Drives with More than 1024 Cylinders If the boot drive is new or just initialized, Windows NT may give a warning message about disk drives having more than 1024 cylinders during the first reboot from the hard drive. Windows NT may hang just after the SCSI BIOS or Disk Array BIOS banner. This is a Windows NT limitation, please see Microsoft TechNet article # Q137474 for details. In some situations, the Windows NT installation program may detect the hard drive geometry incorrectly, and thus limit the initial drive partition size to 1024 MB or hang while rebooting. To correct this problem, perform the following solutions: In the Windows NT installation program: 1. Partition the primary partition to 1024 MB. 2. Format the primary partition using FAT. 15

Installing Microsoft Windows NT 4.0 Server
Tip #1. Troubleshooting SCSI Host Bus Adapter
Configuration
The boot manager for Windows NT contains recovery logic to allow you to return
to the last known good configuration. If you have changed your SCSI host bus
adapter configuration and Windows NT no longer boots, follow these steps to
recover:
1.
Undo any hardware changes you have made to the computer since it was last
operational.
2. Reboot the computer. Press the spacebar when the message appears:
Press spacebar NOW to invoke the Last Known Good
menu.
Follow the instructions on the screen to continue booting.
NOTE
Do not log in if you pass the "Press spacebar NOW to invoke
the Last Known Good screen" option, because this will wipe
out the configuration you want.
3.
Once your computer is operational again, double check all the hardware and
software configuration changes you wish to make. Look specifically for
conflicts with parts of the existing system configuration that are not being
changed. If you cannot determine the source of the error, contact the host
adapter vendor or HP Technical Support for assistance.

Array BIOS banner. This is a Windows NT limitation, please see Microsoft
TechNet article # Q137474 for details.
In some situations, the Windows NT installation program may detect the hard

MB or hang while rebooting. To correct this problem, perform the following
