Microsoft Cairo build 1175.1
|Build of Microsoft Cairo|
Microsoft Cairo build 1175.1 is a late build of Microsoft Cairo, based on the core of Windows NT 4.0 build 1175.1. This build was uploaded to BetaArchive by The Distractor on 17 March 2017. Due to having
MSTOOLS folders in the
I386 directory of the installation media as well as compiler-output file
CHKFILE.BLD listing checksums for each file, this build came directly from MS build servers at the time. The build notably integrates Cairo Object File System support into the build, alongside some updated components for Cairo, such as domain support and an updated login screen.
CHKFILE.BLD also proves Cairo components were built separately (to a
CAIRO folder) and then copied over the base build, something that happened again with Neptune four years later.
New features and changes[edit | edit source]
Shell features[edit | edit source]
- The Object File System is implemented in this build (under the file
OFS.SYS). It is the largest file in this build and is prone to instability due to its incompleteness.
- This build notably contains a completely revamped login screen, which shows the Ctrl+Alt+Del shortcut to login in a graphical appearance.
Application features[edit | edit source]
- This build contains an additional disk utility (
REPART.EXE) intended for OFS partitions.
- Summary Catalog Client (
SCTOOL.EXE) is included to create summary catalogs.
- Replication Metadata Analyzer 2.0 (
REPLANAL.EXE) is added and functions similarly to the Summary Catalog Client.
- A SINGLE utility is included (
SINGLE.EXE), but its function is unknown.
Setup features[edit | edit source]
- During the start of network setup, the setup will ask for a drive to format to OFS.
- Near the end of the setup, it will ask the user to choose whether to install a Domain Controller or Server. If Domain Controller is selected, the user can choose to install FirstDC as the domain controller type.
Bugs and quirks[edit | edit source]
REPART.EXEtriggers a bug in the Option ROM of the NCR 810 SCSI controller on some systems (all-caps strings warn against its use on unknown Dell systems of the era), leading to an unbootable system if used on the boot drive.
Installation[edit | edit source]
This build requires two partitions before starting the GUI setup, as network setup will require a partition to format to OFS. Attempting to install without an OFS partition may result in the setup refusing to continue or a system crash upon rebooting after the GUI setup. If the bootloader is on an OFS partition, the build will hang on boot.
On the Primary Domain Controller dialog, you must Alt+F4 out of the window as it is impossible to get past it due to an "Unable to update local security in order to join domain" error.
During setup, you can choose to install Domain Controller (DC) or Server on the Select Cairo Install Type. If you select Domain Controller, select FirstDC as the domain controller type and leave the domain and OU name as is.
To log into the system, use the username entered during setup as both the username and password. If you installed the Domain Controller, leave the "From" section as it is (
\msft\redmond\bsd\dev\), otherwise use the computer name entered during setup.

Windows Explorer[edit | edit source]
The first time you load
EXPLORER.EXE on each boot, you must use Ctrl+Alt+Del and log off, since each time Explorer first loads, it will hang loading. You can then log in again normally. Most functions in Explorer such as changing the background can cause Explorer to hang and force you to log out and back in again to regain control.
