Installing Windows NT Server 4.0 (DR/2)
6.1. Determining Whether Software Is Preloaded
Caution
To prevent installation problems, or wasted time, determine whether Windows NT
has been preloaded. Then follow either the procedure for preloaded software or
the full installation procedure, as appropriate.
To determine whether the Windows NT operating system is preloaded,
1. Power on the Intel node and allow it to fully boot (takes about 2 minutes).
2. If the Windows NT Software License Agreement screen appears, the operating system
is preloaded.
If Windows NT is preloaded, perform the steps described in 6.2. Then complete the
installation as described in Section 7.
If Windows NT is not preloaded,
1. Configure the RAID controller (6.3).
2. Install the Windows NT operating system (6.4).
3. Log on to Windows NT (6.5).
4. Complete the installation (Section 7).
6.2. Steps to Take If Windows NT Is Preloaded
You must take the steps below to initially configure Windows NT when it is preloaded.
Notes:
• Before powering on the Intel node, verify that the preloaded RAID disks are installed
into the correct bays as labeled on the disks. See the DR/2 system map for the
location and layout of the drive bays.
• If you decide to perform a full installation even though the system is preloaded, do
not format the RAID disk. Instead, use the DAC BIOS utility to initialize the RAID
volume before you reload the operating system. Formatting the disk makes the drive
unrecognizable to the software.
1. Power the Intel node on and allow it to fully boot (takes about 2 minutes).
Watch the messages on the screen for the ALT-R prompt.
2. Press Alt-R to start the Mylex RAID EzAssist utility.
An EzAssist Menu for configuring RAID logical arrays appears as follows:
