NT BOOT DISK
Boot disk which you can use to boot off an NT partition installation.
Useful if:
1. The partition you boot off of has problems (i.e. boot record messed up),
or,
2. Any of the boot files are corrupt or missing.
- To Create an NT Boot Disk:
1. Format disk in an NT system (using NT's format command)
2. Copy the NT boot files to the diskette: NTLDR, Boot.ini, NTDETECT.com
FILE SYSTEMS
File Systems in NT
- Choices: FAT or NTFS
- NT does NOT support FAT32 – without a 3rd party patch.
NT FAT - enhanced version of DOS's FAT version; supports long
filenames
- Advantages of NT FAT (vs. NTFS)
- Can be read by other operating systems that can't read NTFS - DOS, W9x,
W3.x. (This is especially useful if the machine is set up for dual boot).
- Can be accessed via a DOS boot disk in times of operating system
trouble.
- Efficient for partition sizes < 400 MB.
- Disadvantages of NT FAT (vs NTFS)
- No security measures
- Max partition size = 4 GB in NT (Reason: NT max cluster size = 64K; W9x
max cluster size = 32 K
NTFS
- Security - Security can be set for any user or group on any file and
folder.
- Partition size maximums:
1. Theoretical maximum = 16 exabytes
2. Functional maximum = 2 TB (industry limitation)
3. Minimum recommended = 50 MB
- Reduced fragmentation (according to MS, but still need to run a
defragmenter)
- Increased recoverability – keeps track of more information to be able to
recover better from disk problems.
- Disadvantages of NTFS (vs FAT)
- Can't be used on a floppy due to overhead involved in file system.
- Is only supported by NT (and Windows 2000)
- Not effective on small partitions (<400 mb)
Converting between FAT and NTFS
- Conversion can occur from FAT to NTFS, using NT tools, but not back again.
(Third party tools exist to convert from NTFS to FAT).
- Use the CONVERT utility at the command prompt to perform
conversion.
MICROSOFT SYSTEM UPDATES
Kernel Builds
- Viewed in Windows NT Diagnostics
- Reflects the core kernel build number of the installed operating
system.
Service Packs
- What are they: Minor updates to the operating system (usually of drivers,
patches, bug fixes) between major releases.
- Service packs exist for most Microsoft products: operating systems (NT,
W9x, 2000), Backoffice products (SMS, SNA, SQL, IIS…), Applications (Office97,
2000)
- Tips on using MS service packs:
- Service packs (SPs) should be installed after the main product is
installed.
- Typically SPs need to be reinstalled after you make any changes
to the system (such as adding new software or hardware).
- The order of installation is significant and can be challenging to keep
track of particularly when working with multiple Microsoft
products.
- You probably don't want to be the first on your block to install a new
service pack as soon as it becomes available.
- Good idea to allow the SP installation to create an uninstall
directory. In the event the SP creates more problems and you can
uninstall it.
- Log when service packs were installed. If you restore a backup of the
system from before the service pack was installed, you would need to
reinstall the SP.
- Latest SP for Windows NT: SP 6a released November 99.
- Service packs are cumulative: the latest SP contains material from
previous service packs.
Hot fixes
- Minor patches to particular problems
- Released between service packs.
- Recommendation: Only install hot fixes which address specific problems you
are having. Do not install hot fixes on general principle. Reason: full
testing is not completed before a hot fix is released.
Availability
- Both service packs and hot fixes are available on Microsoft’s web site for
free.
- Most available on TechNet CDs as the CDs are released.
