This soft copy for use by IBM employees only.
You are now presented with a list of Hardware Abstraction Layer choices.
Table 4 on page 91 lists the appropriate HAL choices for each server.
It is also recommended that you use any IBM-supplied HAL diskette if it is more
current than the one supplied with the NT 4.0 CD-ROM. To confirm which
version of the HAL is more current, check the time/date stamps on the files on
the diskette and compare them to the equivalent files on the CD-ROM.
Note: The files on the CD-ROM may be compressed and may have different file
extensions that indicate they are compressed.
Change the default selections as appropriate. To continue the installation
process, select The above list matches my computer and press Enter to continue.

325 MPS Multiprocessor PC

520 MPS Multiprocessor PC
704 MPS Multiprocessor PC

5.3.7.1 Multiprocessor Capable Machines
If your server is multiprocessor capable, but it is currently equipped with one
processor only, setup will detect a single processor and thus select the MPS
Uniprocessor PC option. However, it is strongly recommended that you change
this selection to MPC Multiprocessor PC. Windows NT will also support a single
processor even though the multiprocessor kernel is loaded.
If you intend to upgrade your system later with a second processor, all you need
to do is to shut down and power off your server, install the second processor
and then reboot your server. Windows NT automatically recognizes the
existence of a second processor and will activate it during the boot process.
If you don′t select the MPC Multiprocessor PC option during the initial NT 4.0
installation process, you need to use the multiprocessor upgrade utility that is
supplied with the resource kit (it is often not successful). Alternatively, you will
have to reinstall Windows NT in order to provide multiprocessor support.
Note: Refer to Appendix E, “The Hardware Abstraction Layer (HAL)” on
page 159 for details on how to use the multiprocessor upgrade utility.
5.3.8 Partitioning
We recommend that you partition your disk prior to commencing the installation
process, as discussed in 3.6, “Disk Partitioning” on page 65. If you have
followed the recommendations, a panel similar to the one in Figure 66 on
page 92 will appear. However, it will show the partition you created plus any
unpartitioned (free) space left on the disk. You can press Enter and continue
with 5.3.9, “Formatting” on page 93.
